White Paper, Miner, Pizza … | "Old Objects" in the Cryptocurrency Museum

White Paper, Miner, Pizza … |
https://preview.redd.it/giu1ssilga151.jpg?width=900&format=pjpg&auto=webp&s=41510785ccdc0d99544ec74229f62427d1c0ce3e
Museum has played the role of a time recorder. Talking about bitcoin, more than ten years has passed since the creation of it. Although it is uncomparable to the stock market with a hundred years of history, during the ten years, in the different stages of the development of bitcoin and blockchain have continuously poured in geeks, miners, speculators, newbies, leaving keywords such as sudden rich, myth, scam, belief, revolution, etc.
There are also many “old objects” with stories in the “Museum” of the cryptocurrency realm. On Museum Day, let ’s review the stories brought by these “old objects”.
The First Digital Currency White Paper — Bitcoin White Paper
On Oct. 31, 2008, Satoshi Nakamoto released the Bitcoin white paper — A Peer-to-Peer Electronic Cash System in the cryptographic mail group where he belongs, and Bitcoin was born since then.
A white paper is a document that explains the purpose and technology used in cryptocurrency. Usually a cryptocurrency uses the white paper to help people understand what it provides, and it is also an important information channel for investors to understand a project. Therefore, the level of the white paper affects people’s confidence towards the coin.
In a word, in the cryptocurrency and blockchain industry, the value of a white paper is equivalent to that of a standard financing speech. The white paper plays a vital role in this emerging market.
The First Public Bitcoin-Physical Transaction — Pizza
Since Satoshi Nakamoto mined the Bitcoin genesis block on January 3, 2009, Bitcoin has only been spread among the small crowd and has not realized its value.
Not until May 22, 2010, Bitcoin enthusiast “Laszlo Hanyecz” bought a pizza coupon worth $25 with 10,000 bitcoins. This is the first public bitcoin-physical transaction. Bitcoin has its price with 0.3 cents per bitcoin.


This day has also become the famous “Bitcoin Pizza Day” in Bitcoin history. Bitcoin as the imagination of the financial system has more practical significance. The tenth anniversary is coming. How will you commemorate it? Will you buy a pizza?
The First Digital Asset Exchange — Bitcoinmarket.com
After the birth of Bitcoin, in addition to mining, the only way to get Bitcoin in the early days was to conduct transactions on forums or IRC (commonly known as Internet Relay Chat). However, this method involves both long transaction time and great security risk.
In March 2010, the first digital asset exchange — Bitcoinmarket.com launched. However, due to lack of liquidity and transaction depth, it disappeared soon after its establishment, but Bitcoinmarket.com opened the era of the operation of the cryptocurrency realm exchange 1.0.


On June 9, 2011, China’s first Bitcoin exchange — Bitcoin China (BTCChina) launched. Its founder, Yang Linke, translated Bitcoin into Chinese “比特币” for the first time. In 2013, China’s bitcoin trading entered the golden age, and exchanges sprung up. China monopolized more than 90% of the world’s bitcoin transactions. Now, if the top three exchanges Binance, Huobi Global, OKEx are the Exchange 2.0, then the index exchange represented by 58COIN called the 3.0 version, leading the trend.
The First Generation of High-Performance Miner — ASIC Miner
When Satoshi Nakamoto created Bitcoin, the only way to get it is to use computers (including home computers) to mine, mainly relying on the CPU to calculate. However, as the value of digital currencies such as Bitcoin has become higher and higher, mining has become an industry with the competition is getting fiercer, accompanied by increasing difficulty of mining. Therefore, hardware performance competition starts.
In July 2012, the genius Jiang Xinyu (Internet nickname is “Friedcat”) from the junior class of the University of Science and Technology declared at the forum that he could make ASIC miners (chips). As far as mining computing power is concerned, ASICs can be tens of thousands or more higher than the same-generation CPUs and GPUs.
At the beginning of 2013, Zhang Nanqian (Pumpkin Zhang), a suspended doctoral student from the Beijing University of Aeronautics and Astronautics, developed the ASIC miner and named it “Avalon”.


In June 2013, the Friedcat’s miner USB was finally released, and it maintained 20% of the computing power of the entire network.
At the end of 2013, Wu Jihan, used the tens of millions yuan earned from Friedcat through investment, worked together with Jenke group, to develop the Antminer S1. Since then, the miner manufacturer Bitmain began to enter the stage of history.
It is no exaggeration to say that Friedcat and Zhang Nangeng have opened the domestic “mining” era.
The Birthplace of China’s Bitcoin — Garage Coffee
It is not only the “old objects” that record history, but also a place that everyone in the cryptocurrency realm aspires to.
Guo Hongcai once said, “Without no The Garage Café, there will be no cryptocurrency realm today. Since it is a very mysterious place that all waves of people from the café joint together to create today’s digital asset industry.

▲ In March 2013, American student Jake Smith successfully purchased a cup of coffee at The Garage Café with 0.131 bitcoins. This move attracted the attention of CCTV, and it conducted an interview.
Indeed, The Garage Café is the world ’s first entrepreneurial-themed coffee shop. It has been legendary since its establishment in 2011. The Garage Cafét is not only the core coordinate on China’s Bitcoin map, but also the birthplace of the Chinese cryptocurrency circle, where digital asset realm tycoons including Guo Hongcai, Zhao Dong, Li Xiaolai, Li Lin have made their ways.
The development of digital currency is only 11 years old. Through these “old objects”, we review the various stories of this wave of technology together, hoping to help you understand the development process of the digital currency field. Meanwhile, I also remind all practitioners to use history as a mirror and forge ahead.

I have a Bitcoin Core Wallet from 2013.

So, from around 2010 to 2014 I used to mess around with mining Bitcoin. I started with CPU mining then bought a dozen of those usb asic miners then acquired a couple blade miners. My backup was to have multiple copies of my Core wallet so I wouldn't lose the coins. My failure was to keep multiple copies of the password. I used KeePass to store my password. Long story short, the KeePass database appears to be lost forever. I only know that the password is 32 characters long. By examining passwords generated by the software I can assume that it only contains no more than 3 of each characters and no two characters repeat simultaneously. It could contain upper case, lower case, and special characters.
With my video card I can only brute force 5000 passwords per second. At today's bitcoin price it is not practical to invest in more computing power but someday for my kids it could be worth it.
Right now it is just a project I am working on because these challenges intrigue me. I assume with a 12 GPU mining rig I could get more than 60,000 passwords per second but it would still be a matter of luck to crack it before I die.
...and go

I literally have tens of thousands of dollars in top-shelf hardware, looking to repurpose some before selling on eBay to build a NAS system, possibly a dedicated firewall device as well. o_O

Q1) What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.**

A1) This will be a dedicated NAS system for my home network. As such, I'm looking to have it:

- Host ##TB's of 720, 1080 & up resolution Movies and TV Shows I'm about to begin ripping from a MASSIVE DVD & Blueray collection I have.

- My kids are big on Minecraft. I understand it's possible to host your own "worlds" (or whatever they call the maps you can build) on your own "server". I think it would be pretty neat to offer them (& their friends - if can be done 'safely/securely') their own partition on one of my NAS HDD's.

- I also have accounts with a couple diff VPN companies... I understand it's possible (?) to sync said VPN's with a NAS, this might be a more relative topic on the next point/purpose...

- I'd like to be able to remotely link to this NAS for when I travel overseas and want to stream at my temp location from my house/this NAS.
______________________
Q2) What is your maximum budget before rebates/shipping/taxes?**

* A2) Here's where I make matters more complicated than most others would... I've been an advocate for Bitcoin and crypto-currencies in general since 2013. I invested in a small mining outfit back in 2014 (strictly Bitcoin/ASIC's). One of my buddies is the President of a large-scale mining operation (foreign and domestic) and he convinced me to dabble in the GPU mining-space. I made my first hardware purchase in Q4, 2017 and launched a small-scale GPU-Farm in my house since then. I had the rigs mining up until Q3 of 2018 (not cost-efficient to keep on, especially living in SoFlo) and since then, the hardware's been collecting dust (& pissing off my family members since they lost access to 3X rooms in the house - I won't let anyone go near my gear). One of my New Years Resolutions for 2019 was to clear out the house of all my mining equipment so that's all about to go up on eBay. So "budget" is relative to whatever I "MUST" spend if I can't repurpose any of the parts I already have on hand for this build... (Anyone having something I "need" and is looking to barter for one of the items I'll list later on in here, LMK).
______________________
Q3) When do you plan on building/buying the PC? Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.**

A3) IMMEDIATELY! :)
______________________
Q4) What, exactly, do you need included in the budget? (ToweOS/monitokeyboard/mouse/etc\)**

A4) Well I had a half-assed idea approximately 1 year ago that it might be wise to build a bunch of 'gaming rigs' to sell on eBay with my intended repurposed mining hardware so I went on a shopping spree for like 6 months. That said; I've got a plethora of various other components that aren't even unboxed yet. 90% of the items I've purchased for this additional project were items that were marked down via MIR (mail-in-rebates) & what-not...
AFAIK, there are only 3X items I absolutely do not have which I 'MUST' find. Those would be - 1) Motherboard which accepts "ECC RAM". 2) CPU for said MOBO. 3) Said "ECC RAM".\* 
______________________
Q5) Which country (and state/province) will you be purchasing the parts in? If you're in US, do you have access to a Microcenter location?**

A5) I'm located in Southwest Florida. No Microcenter's here. Best Buy is pretty much my only option although I am a member of Newegg, Amazon & Costco if that makes any difference?
______________________
Q6) If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.**

A6) In an attempt to better clean up this Q&A, I'm going to list the items I have on-hand at the end of this questionnaire in-case passers-by feel like this might be a TLDR.* (Scroll to the bottom & you'll see what I mean).
______________________
Q7) Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?**

A7) I don't think that's necessary for my intended purpose although - I'm not against it if that helps & FWIW, I'm pretty skilled @ this task already (it's not rocket science).
______________________
Q8) Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc)**

A8) As stated in A4; ECC RAM is non-negotiable... RAID seems like a logical application here as well.

- This will predominantly be receiving commands from MacOS computers. I don't think that matters really but figured it couldn't hurt to let you guys know.\*

- I'd also be quite fond of implementing "PFSENSE" (or something of that caliber) applied to this system so I could give my Netgear Nighthawks less stress in that arena, plus my limited understanding of PFSENSE is that it's ability to act as a firewall runs circles around anything that comes with consumer-grade Wi-Fi routers (like my Nighthawks). Just the same, I'm open to building a second rig just for the firewall.\*

- Another desirable feature would be that it draws as little electricity from the wall as possible. (I'm EXTREMELY skilled in this arena. I have "Kill-A-Watts" to test/gauge on, as well as an intimate understanding of the differences between Silver, Gold, Platinum and Titanium rated PSU's. As well as having already measured each of the PSU's I have on-hand and taken note of the 'target TDP draw' ("Peak Power Efficiency Draw") each one offers when primed with X amount of GPU's when I used them for their original purpose.\*

- Last, but not least, sound (as in noise created from the rig). I'd like to prop this device up on my entertainment center in the living room. I've (almost) all of the top-shelf consumer grade products one could dream of regarding fans and other thermal-related artifacts.

- Almost forgot; this will be hosting to devices on the KODI platform (unless you guys have better alternative suggestions?)
______________________
Q9) Do you have any specific case preferences (Size like ITX/microATX/mid-towefull-tower, styles, colors, window or not, LED lighting, etc), or a particular color theme preference for the components?**

A9) Definitely! Desired theme would be WHITE. If that doesn't work for whatever reason, black or gray would suffice. Regarding "Case Size". Nah, that's not too important although I don't foresee a mini-ITX build making sense if I'm going to be cramming double digit amounts of TB in the system, Internal HDD's sounds better than a bunch of externals plugged in all the USB ports.
______________________
Q10) Do you need a copy of Windows included in the budget? If you do need one included, do you have a preference?**

A10) I don't know. If I do need a copy of Windows, I don't have one so that's something I'll have to consider I guess. I doubt that's a necessity though.

______________________
______________________
______________________
Needless to say, I have at least 1X of everything mentioned above. In most all cases, I have multiples of these items but obviously won't be needing 2X CPU's, Cases, etc...

Naturally, I have GPU's. Specifically;

At least 1X of every. Single. NVIDIA GTX 1070 TI (Yes, I have every variation of the 1070 ti made by MSI, EVGA and Zotac. The only brand I don't have is the Gigabyte line. My partners have terrible experience with those so I didn't even bother. I'm clearly not going to be needing a GPU for this build but again, I'm cool with discussing the idea of a barter if anyone reading this is in the market for one.

I also have some GTX 1080 TI's but those are already spoken for, sorry.

It's my understanding that select CPU's I have on this list are ECC Friendly and AFAIK, only 1 of my MOBO's claims to be ECC Friendly (The ASROCK AB350M PRO4), but for the life of me, I can't find any corresponding forums that confirm this and/or direct me to a listing where I can buy compatible RAM. Just the same, if I go w/ the ASROCK MOBO, that means I'd be using one of the Ryzens. Those are DEF. power hungry little buggers. Not a deal-breaker, just hoping to find something a little more conservative in terms of TDP.


In closing, I don't really need someone to hold my hand with the build part as much as figuring out which motherboard, CPU and RAM to get. Then I'm DEFINITELY going to need some guidance on what OS is best for my desired purpose. If building 2X Rigs makes sense, I'm totally open to that as well...
Rig 1 = EPIC NAS SYSTEM
Rig 2 = EPIC PFSENSE (or the like) DEDICATED FIREWALL

Oh, I almost forgot... The current routers I'm using are...
1X Netgear Nighthawk 6900P (Modem + Router)
1X Netgear Nighthawk X6S (AC 4000 I believe - Router dedicated towards my personal devices - no IoT &/or Guests allowed on this one)
1X TP-Link Archer C5 (Router). Total overkill after implementing the Nighthawks but this old beast somehow has the best range, plus it has 2X USB ports so for now, it's dedicated towards my IoT devices.
---- I also have a few other Wi-Fi routers (Apple Airport Extreme & some inferior Netgear's but I can only allocate so many WiFi Routers to so many WiFi channels w/out pissing off my neighbors) On that note, I have managed to convince my neighbors to let me in their house/WiFi configuration so we all have our hardware locked on specific, non-competing frequencies/channels so everyone's happy. :)


Please spare me the insults as I insulted myself throughout this entire venture. Part of why I did this was because when I was a kid, I used to fantasize about building a 'DREAM PC' but could never afford such. To compensate for this deficiency, I would actually print out the latest and greatest hardware components on a word document, print the lists up & tape to wall (for motivation). I was C++ certified at the age of 14 and built my first PC when I was 7. At the age of 15 I abandoned all hope in the sector and moved on to other aspirations. This entire ordeal was largely based off me finally fulfilling a childhood fantasy. On that note = mission accomplished. Now if I'm actually able to fulfill my desires on this post, I'm definitely going to feel less shitty about blowing so much money on all this stuff over the last couple years.

TIA for assisting in any way possible. Gotta love the internets!


THE END.
:)

EDIT/UPDATE (5 hours after OP) - My inbox is being inundated with various people asking for prices and other reasonable questions about my hardware being up for sale. Not to be redundant but rather to expound on my previous remarks about 'being interested in a bartetrade' with any of you here...

I did say I was going to sell my gear on eBay in the near future, I also said I wanted to trade/barter for anything relative to helping me accomplish my OP's mission(s). I'm not desperate for the $$$ but I'm also not one of those people that likes to rip other people off. That said; I value my time and money invested in this hardware and I'm only willing to unload it all once I've established I have ZERO need for any of it here in my home first. Hence my writing this lengthy thread in an attempt to repurpose at least a grand or two I've already spent.

One of the most commonly asked questions I anticipate receiving from interested bodies is going to be "How hard were you on your hardware?" Contrary to what anyone else would have probably done in my scenario which is say they were light on it whether they were or weren't, I documented my handling of the hardware, and have no problem sharing such documentation with verified, interested buyers (WHEN THE TIME COMES) to offer you guys peace of mind.

I have photo's and video's of the venture from A-Z. I am also obliged to provide (redacted) electricity bill statements where you can correlate my photo's (power draw on each rig), and also accurately deduct the excess power my house consumed with our other household appliances. Even taking into consideration how much (more) I spent in electricity from keeping my house at a constant, cool 70-72F year-round (via my Nest thermostat). Even without the rigs, I keep my AC @ 70 when I'm home and for the last 1.5-2 years, I just so happened to spend 85% of my time here at my house. When I would travel, I'd keep it at 72 for my wife & kids.
Additionally; I had each GPU 'custom' oveunderclocke'd (MSI Afterburner for all GPU's but the EVGA's).*
I doubt everyone reading this is aware so this is for those that don't.... EVGA had the brilliant idea of implementing what they call "ICX technology" in their latest NVIDIA GTX GPU's. The short(est) explanation of this "feature" goes as follows:

EVGA GPU's w/ "ICX 9 & above" have EXTRA HEAT/THERMAL SENSORS. Unlike every other GTX 1070 ti on the market, the one's with this feature actually have each of 2/2 on-board fans connected to individual thermal sensors. Which means - if you were to use the MSI Afterburner program on one of these EVGA's and create a custom fan curve for it, you'd only be able to get 1/2 of the fans to function the way intended. The other fan simply would not engage as the MSI Afterburner software wasn't designed/coded to recognize/ communicate with an added sensor (let alone sensor'S). This, in-turn, would likely result in whoever's using it the unintended way having a GPU defect on them within the first few months I'd imagine... Perhaps if they had the TDP power settings dumbed down as much as I did (60-63%), they might get a year or two out of it since it wouldn't run as near as hot, but I doubt any longer than that since cutting off 50% of the cooling system on one of these can't be ignored too long, surely capacitors would start to blow and who knows what else...
(Warning = RANT) Another interesting side-note about the EVGA's and their "Precision-X" OveUnderclocking software is that it's designed to only recognize 4X GPU's on a single system. For miners, that's just not cool. My favorite builds had 8X and for the motherboards that weren't capable of maintaining stable sessions on 8, I set up with 6X. Only my EVGA Rigs had 3 or 4X GPU's dedicated to a single motherboard. Furthermore, and as stated in an earlier paragraph, (& this is just my opinion) = EVGA SOFTWARE SUCKS! Precision X wasn't friendly with every motherboard/CPU I threw at it and their extension software for the CLC Close-Loop-Cooling/ CPU water-coolers simply didn't work on anything, even integrating into their own Precision-X software. The amount of time it took me to finally find compatible matches with that stuff was beyond maddening. (END RANT).
Which leads me to my other comments on the matter. That's what I had every single 1070 ti set at for TDP = 60-63%. Dropping the power load that much allowed me to bring down (on average) each 1070 ti to a constant 110-115W (mind you, this is only possible w/ "Titanium" rated PSU's, Platinum comes pretty damn close to the Titanium though) while mining Ethereum and was still able to maintain a bottom of 30 MH/s and a ceiling of 32 MH/s. Increasing the TDP to 80, 90, 100% or more only increased my hashrates (yields) negligibly, like 35-36 MH/s TOPS, which also meant each one was not only pulling 160-180W+ (Vs. the aforementioned 115'ish range), it also meant my rigs were creating a significantly greater amount of heat! Fortunately for the GPU's and my own personal habits, I live in South Florida where it's hot as balls typically, last winter was nothing like this one. Increasing my yields by 10-15% didn't justify increasing the heat production in my house by >30%, nor the added electricity costs from subjecting my AC handlers to that much of an extra work-load. For anyone reading this that doesn't know/understand what I'm talking about - after spending no less than 2-3 hours with each. and. every. one. I didn't play with the settings on just one and universally apply the settings to the rest. I found the 'prime' settings and documented them with a label-maker and notepad. Here's the math in a more transparent manner:

*** I NEVER LET MY GPU's BREACH 61C, EVER. Only my 8X GPU rigs saw 60-61 & it was the ones I had in the center of the build (naturally). I have REALLY high power fans (used on BTC ASIC MINERS) that were sucking air from those GPU's which was the only way I was able to obtain such stellar results while mining with them. **\*
Mining at "acceptable" heat temps (not acceptable to me, but most of the internet would disagree = 70C) and overclocking accordingly brings in X amount of yields per unit. =
'Tweaking' (underclocking) the GPU's to my parameters reduced my yield per unit from -10-15%, but it SAVED me well over 30-35% in direct electricity consumption, and an unknown amount of passive electricity consumption via creating approximately 20%+ less heat for my AC handler to combat.

I say all this extra stuff not just for anyone interested in mining with their GPU's, but really to answer (in-depth) the apparent questions you people are asking me in PM's. Something else that should help justify my claims of being so conservative should be the fact I only have/used "Platinum and Titanium" rated PSU's. Heat production, power efficiency and longevity of the hardware were ALWAYS my top priority.* . I truly thought Crypto would continue to gain and/or recover and bounce back faster than it did. If this project had maintained positive income for 12 months+, I'd have expanded one of our sites to also cater to GPU mining on a gnarly scale.

Once I have my NAS (& possibly 2nd rig for the firewall) successfully built, I'll be willing/able to entertain selling you guys some/all of the remaining hardware prior to launching on eBay. If there's something you're specifically looking for that I listed having, feel free to PM me with that/those specific item(s). Don't count on an immediate response but what you can count on is me honoring my word in offering whoever asks first right of refusal when the time comes for me to sell this stuff. Fortunately for me, PM's are time-stamped so that's how I'll gauge everyone's place in line. I hope this extra edit answers most of the questions you guys wanted to have answered and if not, sorry I guess. I'll do my best to bring light to anything I've missed out on after I realize whatever that error was/is. The only way anyone is getting first dibs on my hardware otherwise is if they either offer compelling insight into my original questions, or have something I need to trade w/.

THE END (Round#2)

Before I jump to much into Litecoin and mining, I have some concerns and questions.

I have been looking and reading up on litecoin and even though I could see mining becoming a hobby I do have some concerns about it.
These may be newb questions but I hope some veteran miners can answer some of my questions.

Reddit Block Erupter USB (ASICMiner USB miner) Group Buy!

DUE TO LACK OF INTEREST, I AM CANCELLING THIS EARLY DO NOT SEND FUNDS THE TEXT IS BEING KEPT FOR ARCHIVAL PURPOSES
With the announcement of new USB Mining Hardware from ASICMiner (https://bitcointalk.org/index.php?topic=195004.msg2025318#msg2025318), I'm sure a lot of people are yelling "SHUTUP AND TAKE MY MONEY" but can't quite afford the minimum purchase of "more than 300 devices." I therefor propose a Reddit group buy.
Terms:
My Responsibilities:
Within one hour of making this post, I will send friedcat a private message expressing interest in purchasing a group of Block Erupters.
I will keep an encrypted wallet on my computer, with an updated backup of the encrypted wallet.dat on the cloud at all times.
Within 72 hours of receipt of confirmed orders for 301 Block Erupters, I will post on this subreddit that the minimum number of orders has been reached, and, if possible, give everyone 24 hours to get final orders in. I reserve the right to place the order immediately, without the above notice, if, in my judgment, delay would risk an inability to secure an order with ASICMiner.
Upon receiving Block Erupters from ASICMiner, I will ship all units with tracking information within 72 hours.
Upon request, I will provide any of the moderators of this subreddit with my personal information, including full name, address, telephone number, and a copy of state issued ID.
If ASICMiner will not accept my order, or if by May 31, 2013, this groupbuy has not received 301 orders, then within 72 hours I will return all bitcoins sent, less transaction fees.
** Your Responsibilities **
To place an order for (a) Block Erupter(s):
  1. Send 2.04 BTC (or 2.14 BTC if shipping outside the US) per Block Erupter ordered to
1MKSrWLnfmShjHViDMngVdB7QM1frLML2h
  1. Post the transaction ID and bitcoin address to use to return coins to in the event that the group buy fails as a new reply in this thread.
  2. Private message me with your shipping address.
** Other Terms **
All disputes under this agreement shall be governed by the laws of the State of California. Parties agree to submit to the personal and exclusive jurisdiction of the courts located within the county of Santa Clara, California.
No party to this agreement shall be held liable for failure of ASICMiner to ship Block Erupters.
Damages for breach shall be limited to return of bitcoins.
In the event that not all orders by reddit users can be filled, Block Erupters will be sent out on a first ordered, first shipped basis.
So, other stuff (not part of contract). Let me try to answer some of your likely concerns:
This is a scam/Why should I trust you?
Of course, you're welcome not to. That being said, here's a few reasons you might think I'm trustworthy:
Why all the legalese?
Like I just said, I'm a law student ;-)
That being said, this is pretty straight forward.
In the first section, I'm saying I'll keep the coins I receive safe, give the reddit community a last chance to get in on the order, place the order promptly, and ship the order. If I can't do that, I'll refund your bitcoins (none of the BFL bullshit where they take your bitcoins, wait for the market to explode, and refund you in cash).
If you want to order, send me money, post here with proof that you did so, and PM me where to ship your order to.
The other stuff: Don't sue me in timbuktu, don't sue me if ASICMiner does something wrong. If something does go wrong, don't expect anything more than getting your bitcoins back. I will ship out orders first made, first shipped.
I don't have bitcoins - can I use paypal or something?
Nope; that might make me a money transmitter under FinCEN regs, and I'm not bonded for that.
For what it's worth though, I'm in the same boat as you! I'll be using localbitcoins to buy some tomorrow.

Where we're headed with ASIC mining. tl;dr included

As devices flood the mining market, we're bound to see some volatility in the Bitcoin exchange rate. Since ASICs are the effective apex of chip design, that means this should be the last major disruption.
A few points about ASICs:
These factors result in some interesting dynamics.
First, there's the obvious matter that devices can now be produced which are virtually plug & play. Neophytes will no longer need to spend days exploring arcane configuration wizardry; participating in Bitcoin is now open to virtually anyone. That isn't too say professional mining operations are going away; they'll be significant parts of a larger ecosystem.
Security of the network is becoming virtually unassailable by any single entity. With the proliferation of custom hardware, the difficulty of attacking the system head-on is rising exponentially.
With such low power usage, devices can be left on anywhere for pennies a day. Earning a return means the network difficulty will have to climb extremely high before they're turned off. That point may take many months or even several years to arrive.
Being produced in quantity means lower cost, eventually. It's a near certainty that some businesses will cater to high end outfits while others sell to the mass market, much the way Intel makes both server and desktop processors.
The direction Bitcoin is headed in because of this is proliferation is up. Accessibility combined with ease of use in acquiring stake in the network creates an incentive structure with a positive feedback loop, at least during growth.
At present, this proliferation has accelerated. Miners have newly-acquired hardware that must be paid off, and various other expenses to be covered. That applies especially to professional shops. This will be a primary downward pressure on Bitcoin price, as will increased efficiency. If coins can be generated more cheaply, competition will still to undercut other bids. To what extent remains to be seen, but it's reasonable to expect some tension.
A serious concern many have is regarding exchange crackdowns by government, and persecution from traditional banks. These efforts mean that it may be more difficult to get money into Bitcoin, but it also means it's more difficult to get it out.
Bitcoin has a market-established value of around USD$100 currently. Businesses and individuals having acquired hardware for mining generally intend to realize a profit. If a return cannot be readily obtained in local currency denomination (dollars, euros, yen, etc), there will be a preference to spend the bitcoins. In either case, the best value possible is sought. Even if they are sold for another currency, the new recipient now holds them and would prefer not to take a loss.
Because of the high amount of investment in mining hardware over a long span of time, miners will be in various stages of profitability. Some may be in the black while many are likely far from breaking even. As ASICs continue shipping, a good portion of them will spend months recouping the initial investment. At the point of break-even, there is little reason to stop operating; the hardware is paid off, and very often the only input cost is power. So long as a miner generates a comfortable margin greater than the input cost, it will stay.
For ASICs, the one-year profitability mark with current generation hardware is in the 100-200,000,000 Bitcoin difficulty range. That means with a network hash rate of about 1,000 Th/s (1 petahash per second), it will take around a year for a ~150 Mh/watt ASIC to pay itself off. Given the network growth during the past six months, this is a strong possibility by the end of 2013.
Miners are constantly competing for a share in an ever more crowded environment - to stop is to lose profitability if break-even has not been achieved. However, by the time network power has reached the petahash level, first-generation ASICs will no longer be making such wild returns. Therefore, since cessation of operation guarantees loss, there are only a few factors that can change:
tl;dr - The incentive structure surrounding Bitcoin is now well-established, and very little can direct it off-course in the near term; hardware will spread, BTC price will rise, usage will grow.
Edit: corrected spelling errors.

New to Bitcoin Mining! What should the first thing I should do?

Hello everyone! I am trying to get into mining but I don't really know how to. How should I start off? Tell me everything! I already I have a Bitcoin wallet through Multibit. That's pretty much all I know. Any help would be greatly appreciated!
submitted by mewoodboy to BitcoinMining [link] [comments]

It's looking pretty grim to me.

Assuming the standard 30% increase estimate holds true(ish) my miners have about six months left in them. I decided to do some research on what to buy next. So far I can't find anything that might even come close to breaking even when priced in bitcoin.
So cheer me up. What preorders do you have in? Do you think the difficulty is going to level off sometime soon?
Edit: Inspiring anecdotes about why mining at a loss is worthwhile would also be appreciated.

I had like 3 friends ask me how to build a PC in the past week so I made this to help them.

(Reddit Edit: Help my improve the document with productive constructive comments on what I got wrong or messed up! Im only human lol
Also a lot of this is supposed to be kinda humorous. I didn't think I had to say that but, hey, its the internet.
I appreciate the positive and productive comments! )
Beginners basic guide to building your own PC as of early 2018
(EDIT: Sorry for being a MSI/Corsair Fanboy)
Heres a collection of thoughts to consider when building your own personal PC
As always Id personally use PCPartPicker.com to configure your parts and for further thoughts on compatibility.
First off building a computer is 100% based around what you plan to use the computer for.
Here are a few uses and generic ideas of what to go for. Audio Editing: Lots of small tasks that need to be completed quickly without lag. - Fast Processor( >4GHZ) - Fast RAM (MHZ) -At least 16 gigs! - Fast Storage, SSD manditorily - M.2 or PCI for best performance. - Shitty Graphics card, graphics card there only to keep the cpu from doing other tasks when working. - Can be a few generations or years old. - Many screens for lots of plug in windows to be open Video Editing: Lots of large to render and files to read. - Multi core processor the more the merrier - SSD for fast read/write of large video files. - Insane graphics card, AMD graphics cards are debatibly better but the nvidia Quadro series are specific for video rendering. Gaming: No more than 4 cores intense graphics card - 92% of games are not coded for more than 4 cores so why spend the extra money for it. - SSD for quick load screens - Nvidia cards, 10 series, the higher the number the better. Titan cards for MAXIMUM OVERDRIVE! Coding: quick processor for lots of small tasks. Ergonomic peripherials? - Dear god please dont use a mechanical keyboard so that your coworkers dont kill you. Home office: Everything can be a few gens behind so you can get the best power per dollar spent. - Sorry that Gateway doesnt exist anymore. I guess try Dell... 
Parts (Expensive Legos)
CPU (tells things to go places and outputs data) Basically three main routes to go for: Intel, AMD, or ASIC. Intel - Gaming, Data center, Hackintosh Pros: Cooler, Faster speed (GHZ), short small tasks faster Cons: $$$$, less cores AMD - Gaming, Personal Computing, Large task processing Pros: Lots of cores, better price per performance, faster processing of large tasks Cons: Hot chips, large chips?, compatibility issues with MacOS. ASIC - "Application-specific integrated circuit" Pros: Does the task that they are made to do insanely efficently, great for mining. Cons: Literally does nothing else. Holy hell these are expensive, very hot (fans will get loud) CPU Cooler (Im a big fan) Most come with an in box cooler that are ok but please buy aftermarket. In Box - the free shitty cooler that comes with the processor. Pros: Free. Cons: Ugly, makes chip run hot, hard to clean Air cooler - oldest type of cooler but new designs are highly efficent. Pros: Only cooler that has the possibility of being 100% quiet, most likely cheaper Cons: large, if cooler isnt large enough for the chips thermal output the fans will be loud. Liquid - Custom pipes are beautiful, AIO is easy to install and offers similare performance. Pros: Looks cool, great temperatures, "quiet" Cons: Water pump has possibility of being loud, possible spills Phase Change - uses the technology of refridgerators to cool the chip Pros: Can overclock until the chip breaks. (whats colder than cold? ICE COLD!) Cons: Loud (compressor noise), Large pipes, just why.... Motherboard (the convienacnce store of computer parts) Really just about what type of I/O you want. - MAKE SURE FORM FACTOR FITS YOUR CASE! (or vice versa) - Look for PCI lanes for expansion. - How many graphic cards do you have? - PCI based interfaces? - PCI SSD? - PCI DAC? - PCI WIFI? - USbs? Network? Audio? - How many lanes of RAM? - DOES IT FIT YOUR PROCESSOR!?! (really tho) - M.2? - How many sata interaces? Good Brands: MSI, ASUS, Gigabyte Bad Brands: AS(s)Rock, Dell Memory (Dory) - The more the merrier - No less than 8gb for a functional windows machine (16 gb to never have a problem) - Use all the lanes your computer has to offer! the more lanes to access the faster the data can travel! -Imagine drinking a milkshake. If the straw is wider you can drink more of the milkshake than a skinny straw. - Faster MHZ for faster data access but give minimal performance differances - Please get ram with heat spreadders unles youre building a server with high airflow. - Make sure the type (DDR3 or DDR4) of RAM matches what your processomotherboard call for. Good Brands: Corsair, G.Skill, Ballistix Storage (Grandpa that remembers everythign about how things used to be but takes forever to learn a new tasK) Speed or massive storage? slower is cheaper. Golden ratio of speed/storage/price is 250-500 gb SSD and a 1+ tb disk drive. *Max speeds listed are for a single drive not RAID* Hard Disk Drives (HDD) - Cheapest and slowest - read/write speeds of < 0.5gb/s - 7200+ RPM or GTFO - Higher Speed drives can access data faster. - Do not move while powered up. physical parts will break. - Larger Cahche = faster Read/Write Speeds Pros: Cheap, Holds massive amounts of data Cons: Slower than molasses in a frezer Reputible Brands: Seagate, WD Solid State Drives (SSD) - necessity for quick boots and fast load screens (can only be re-written to so many times) - SATA based (2.5 inch)- Read/Write speeds capped @ 6 gb/s Pros: Most economical, form factor fits with old computers, Cons: "Slow" compared to other ssd's (but stil 12 times faster than a HDD) - M.2 based - Read/Write speeds capped @ 10 gb/s Pros: Size of a sick of gum! High End but not too expensive to be out of reach. Cons: Expensive for any size over 500 gb - PCI based - Read/Write speeds capped @ 20 gb/s for PCI3, x4 Pros: HOLY BANDWIDTH BATMAN! Faster than that little creepy ghost thats always in the corner of you eye Cons: You might have to take out a loan to buy one. *takes up a x4 PCI Lane* Reputible Brands: Samsung! Corsair, Plextor, Intel, Kingston, Crucial Video Card (that one kid that has thick glasses and is really good at math) - A regular old PCI card that handles all of the video rendering and output for your computer. - ASIC PCI cards. - The PCBs and chips are patented by two main companies but the differances come from line up and varying manufacturer cooling devices. - The more memory the better -NVIDIA (Team Green) Great for gaming, has specific card series for intensive rendering. Lazy driver updates. - Gaming - 900 series - Cheap - Low performance - Can play any video game made befrore 2010 on max settings - 1000 (ten) series - Expensive (thanks bitcoin miners...) - Great for VR! - Video Rendering -Quadro Series - Gaming and Rendering - Titan X - Maxwell based chip same as 900 series cards - Titan XP - Pascal based chip same as 10 series cards -AMD (Team Red) Underdog does the same thing but slighly worse and cheaper. (except video rendering) - Gaming - RX 400 series - Cheap - Hot - RX 500 series - Cheap - Ok at VR and deacent gaming frame rates. - Not bad but not particularly great either. - Video Rendering - Fire Pro series - Gaming and Rendering - Vega series -Good luck finding one to buy lmao Case (Fancy clothing for your parts!) - Similar to human clothing you want it to do a few main things really well with compromises for each extreme. - Durability - Steel - Incredibly durable - Creates Farady cage for components - Heavy af - Magnets, just magnets.... - Rust over time - Aluminium - Light - East to bend for modding or "physical maintenance" - Less likely to rust - Huzzah for Farady cages! - Plastic - Just dont - no electrical Ground - no faraday cage - Light AF! - Breath (Airflow) - positive internal airflow! - larger fans push the same amount of air with less speed/noise - Looks - Window? - RGB - Cool Paint? - Fit all your parts - graphics card length/ clearacne - support for liquid cooling raiators? - How many spots for HDD/SSDs - Motherboard format - Cable management! Power Supply (FIGHT MILK) - Rule of thumb: BUy Powersupply that outputs 1.5 times the wattage that you need. - You can walk further than you can you can run. - The PSU can casually output 50-75% power for much longer than at 90-100% (without failure) - If you never demand enough wattage for it to get hot the fan doesnt have to turn on therefore making it quieter. - Modular means you can remove/replace the cables from the PSU. Reputible Brands: Corsair, EVGA Optical Drive (motorized cup holder) - You can download most things today so I'd suggest against it unless you really NEED to watch/write DVD's/CD's Operating System (software that makes everything work) Windows (Always Updates) - Compatible with just about everything - Easy to learn to code on! - POS inital browser - Likely to get virus's Linux (Penguins are cute) - Unique - takes less resources to run - Barebones - Incredibly personalizable! - Compatibility issues with just about everything MacOS (Linux but more annoying) - It is legal! - Great for art and your grandma that doenst know how to use computers! - User friendly - Compatibility issues with various hardware - Confusing/Limiting coding structure Peripherials (cables everywhere!) - Keyboard (higer Polling rate is better) - Mechanical (key is pressed at an exact stroke length every time - Mouse (Higher Polling rate is better) - more buttons = better? - DPI (Dots Per Inch) - In theory, if a mouse has 1600 DPI, then, if you move your mouse one inch (2.54 cm), the mouse cursor will move 1600 pixels - Higher DPI the faster your cursor is able to be moved. - Monitor - In theory the human eye cant see faster than 60 frames per second. - Keep in mind Pixel ratio! - 4k screen that is 22inches will have more pixels in a square inch than a 4k screen that is 28 inches. - Interface? - DVI (Analog) - thumbscrews..... - can do two monitors with one port! - support for 4k - VGA (Analog) - thumbscrews... - max resolution is 1440p - Display Port (digital) - nice button clip - supports 4k - HDMI (Digital) - 1.2 or higer supports 4k - DAC/Speakers/Headphones - Dont even get me started - Microphone - Dont get me started PT.2 Other (other) - UPS (uninterruptible power supply) Just a battery that allows your computer to have some time if the power ever goes out so that you have time to save your work. - Cable Organization materials! - Zipties - velcro - LED LIGHTING! - Manditory - Extra/Better fans - More pressure, less woosh - IFIXIT Pro Tech Toolkit - becasue who buys just one torx wrench. - Cute kitten mousepad - Yes, it has to be a cat. Dont argue 
This is a very general entry into building computers and what you should buy/look for. If you have any questions/comments send me an e-mail!

Decred Journal – September 2018

Note: you can read this on GitHub (link), Medium (link) or old Reddit (link).

Development

Final version 1.3.0 of the core software was released bringing all the enhancements reported last month to the rest of the community. The groundwork for SPV (simplified payment verification) is complete, another reduction of fees is being deployed, and performance stepped up once again with a 50% reduction in startup time, 20% increased sync speed and more than 3x faster peer delivery of block headers (a key update for SPV). Decrediton's integrations of SPV and Politeia are open for testing by experienced users. Read the full release notes and get the downloads on GitHub. As always, don't forget to verify signatures.
dcrd: completed several steps towards multipeer downloads, improved introduction to the software in the main README, continued porting cleanups and refactoring from upstream btcd.
Currently in review are initial release of smart fee estimator and a change to UTXO set semantics. The latter is a large and important change that provides simpler handling, and resolves various issues with the previous approach. A lot of testing and careful review is needed so help is welcome.
Educational series for new Decred developers by @matheusd added two episodes: 02 Simnet Setup shows how to automate simnet management with tmux and 03 Miner Reward Invalidation explains block validity rules.
Finally, a pull request template with a list of checks was added to help guide the contributors to dcrd.
dcrwallet: bugfixes and RPC improvements to support desktop and mobile wallets.
Developers are welcome to comment on this idea to derive stakepool keys from the HD wallet seed. This would eliminate the need to backup and restore redeem scripts, thus greatly improving wallet UX. (missed in July issue)
Decrediton: bugfixes, refactoring to make the sync process more robust, new loading animations, design polishing.
Politeia: multiple improvements to the CLI client (security conscious users with more funds at risk might prefer CLI) and security hardening. A feature to deprecate or timeout proposals was identified as necessary for initial release and the work started. A privacy enhancement to not leak metadata of ticket holders was merged.
Android: update from @collins: "Second test release for dcrandroid is out. Major bugs have been fixed since last test. Latest code from SPV sync has been integrated. Once again, bug reports are welcome and issues can be opened on GitHub". Ask in #dev room for the APK to join testing.
A new security page was added that allows one to validate addresses and to sign/verify messages, similar to Decrediton's Security Center. Work on translations is beginning.
Overall the app is quite stable and accepting more testers. Next milestone is getting the test app on the app store.
iOS: the app started accepting testers last week. @macsleven: "the test version of Decred Wallet for iOS is available, we have a link for installing the app but the builds currently require your UDID. Contact either @macsleven or @raedah with your UDID if you would like to help test.".
Nearest goal is to make the app crash free.
Both mobile apps received new design themes.
dcrdata: v3.0 was released for mainnet! Highlights: charts, "merged debits" view, agendas page, Insight API support, side chain tracking, Go 1.11 support with module builds, numerous backend improvements. Full release notes here. This release featured 9 contributors and development lead @chappjc noted: "This collaboration with @raedahgroup on our own block explorer and web API for @decredproject has been super productive.".
Up next is supporting dynamic page widths site wide and deploying new visual blocks home page.
Trezor: proof of concept implementation for Trezor Model T firmware is in the works (previous work was for Model One).
Ticket splitting: updated to use Go modules and added simnet support, several fixes.
docs: beginner's guide overhaul, multiple fixes and cleanups.
decred.org: added 3rd party wallets, removed inactive PoW pools and removed web wallet.
@Richard-Red is building a curated list of Decred-related GitHub repositories.
Welcome to new people contributing for the first time: @klebe, @s_ben, @victorguedes, and PrimeDominus!
Dev activity stats for September: 219 active PRs, 197 commits, 28.7k added and 18.8k deleted lines spread across 6 repositories. Contributions came from 4-10 developers per repository. (chart)

Network

Hashrate: started and ended the month around 75 PH/s, hitting a low of 60.5 and a new high of 110 PH/s. BeePool is again the leader with their share varying between 23-54%, followed by F2Pool 13-30%, Coinmine 4-6% and Luxor 3-5%. As in previous months, there were multiple spikes of unidentified hashrate.
Staking: 30-day average ticket price is 98 DCR (+2.4). The price varied between 95.7 and 101.9 DCR. Locked DCR amount was 3.86-3.96 million DCR, or 45.7-46.5% of the supply.
Nodes: there are 201 public listening nodes and 325 normal nodes per dcred.eu. Version distribution: 5% are v1.4.0(pre) dev builds (+3%), 30% on v1.3.0 (+25%), 42% on v1.2.0 (-20%), 15% on v1.1.2 (-7%), 6% on v1.1.0. More than 76% of nodes run v1.2.0 and higher and therefore support client filters. Data as of Oct 1.

ASICs

Obelisk posted two updates on their mailing list. 70% of Batch 1 units are shipped, an extensive user guide is available, Obelisk Scanner application was released that allows one to automatically update firmware. First firmware update was released and bumped SC1 hashrate by 10-20%, added new pools and fixed multiple bugs. Next update will focus on DCR1. It is worth a special mention that the firmware source code is now open! Let us hope more manufacturers will follow this example.
A few details about Whatsminer surfaced this month. The manufacturer is MicroBT, also known as Bitwei and commonly misspelled as Bitewei. Pangolinminer is a reseller, and the model name is Whatsminer D1.
Bitmain has finally entered Decred ASIC space with their Antminer DR3. Hash rate is 7.8 TH/s while pulling 1410 W, at the price of $673. These specs mean it has the best GH/W and GH/USD of currently sold miners until the Whatsminer or others come out, although its GH/USD of 11.6 already competes with Whatsminer's 10.5. Discussed on Reddit and bitcointalk, unboxing video here.

Integrations

Meet our 17th voting service provider: decredvoting.com. It is operated by @david, has 2% fee and supports ticket splitting. Reddit thread is here.
For a historical note, the first VSP to support ticket splitting was decredbrasil.com:
@matheusd started tests on testnet several months ago. I contacted him so we could integrate with the pool in June this year. We set up the machine in July and bought the first split ticket on mainnet, using the decredbrasil pool, on July 19. It was voted on July 30. After this first vote on mainnet, we opened the tests to selected users (with more technical background) on the pool. In August we opened the tests to everyone, and would call people who want to join to the #ticket_splitting channel, or to our own Slack (in Portuguese, so mostly Brazilian users). We have 28 split tickets already voted, and 16 are live. So little more than 40 split tickets total were bought on decredbrasil pool. (@girino in #pos-voting)
KuCoin exchange listed DCBTC and DCETH pairs. To celebrate their anniversary they had a 99% trading fees discount on DCR pairs for 2 weeks.
Three more wallets integrated Decred in September:
ChangeNow announced Decred addition to their Android app that allows accountless swaps between 150+ assets.
Coinbase launched informational asset pages for top 50 coins by market cap, including Decred. First the pages started showing in the Coinbase app for a small group of testers, and later the web price dashboard went live.

Adoption

The birth of a Brazilian girl was registered on the Decred blockchain using OriginalMy, a blockchain proof of authenticity services provider. Read the full story in Portuguese and in English.

Marketing

Advertising report for September is ready. Next month the graphics for all the ads will be changing.
Marketing might seem quiet right now, but a ton is actually going on behind the scenes to put the right foundation in place for the future. Discovery data are being analyzed to generate a positioning strategy, as well as a messaging hierarchy that can guide how to talk about Decred. This will all be agreed upon via consensus of the community in the work channels, and materials will be distributed.
Next, work is being done to identify the right PR partner to help with media relations, media training, and coordination at events. While all of this is coming up to speed, we believe the website needs a refresher reflecting the soon to be agreed upon messaging, plus a more intuitive architecture to make it easier to navigate. (@Dustorf)

Events

Attended:
Upcoming:
We'll begin shortly reviewing conferences and events planned for the first half of 2019. Highlights are sure to include The North American Bitcoin Conference in Miami (Jan 16-18) and Consensus in NYC (May 14-16). If you have suggestions of events or conferences Decred should attend, please share them in #event_planning. In 2019, we would like to expand our presence in Europe, Asia, and South America, and we're looking for community members to help identify and staff those events. (@Dustorf)

Markets

In September DCR was trading in the range of USD 34-45 / BTC 0.0054-0.0063. On Sep 6, DCR revisited the bottom of USD 34 / BTC 0.0054 when BTC quickly dropped from USD 7,300 to 6,400. On Sep 14, a small price rise coincided with both the start of KuCoin trading and hashrate spike to 104 PH/s. Looking at coinmarketcap charts, the trading volume is a bit lower than in July and August.
As of Oct 4, Decred is #18 by the number of daily transactions with 3,200 tx, and #9 by the USD value of daily issuance with $230k. (source: onchainfx)
Interesting observation by @ImacallyouJawdy: while we sit at 2018 price lows the amount locked in tickets is testing 2018 high.

ASICMiner Erupter Video Unboxing and Review

ASICMiner Erupter Video Unboxing and Review submitted by enmaku to Bitcoin [link] [comments]

Can we talk about the centralization of mining again?

This is one aspect that, despite searching, I don't feel I've found an adequate answer to. As mining becomes more and more expensive, I can only see mining migrating to the hands of a few. Some could argue it's already done that.
Is this a problem that will need to be addressed?

I had like 3 friends ask me how to build a PC in the past week so I made this to help them. Feel free to use or send me an e-mail if you want the txt file

(Reddit Edit: Help my improve the document with productive comments on what I got wrong or messed up! Im only human lol
Also a lot of this is supposed to be kinda humorous. I didn't think I had to say that but, hey, its the internet.
I appreciate the positive and productive comments! )
Beginners basic guide to building your own PC as of early 2018
(EDIT: Sorry for being a MSI/Corsair Fanboy)
Heres a collection of thoughts to consider when building your own personal PC
As always Id personally use PCPartPicker.com to configure your parts and for further thoughts on compatibility.
First off building a computer is 100% based around what you plan to use the computer for.
Here are a few uses and generic ideas of what to go for. Audio Editing: Lots of small tasks that need to be completed quickly without lag. - Fast Processor( >4GHZ) - Fast RAM (MHZ) -At least 16 gigs! - Fast Storage, SSD manditorily - M.2 or PCI for best performance. - Shitty Graphics card, graphics card there only to keep the cpu from doing other tasks when working. - Can be a few generations or years old. - Many screens for lots of plug in windows to be open Video Editing: Lots of large to render and files to read. - Multi core processor the more the merrier - SSD for fast read/write of large video files. - Insane graphics card, AMD graphics cards are debatibly better but the nvidia Quadro series are specific for video rendering. Gaming: No more than 4 cores intense graphics card - 92% of games are not coded for more than 4 cores so why spend the extra money for it. - SSD for quick load screens - Nvidia cards, 10 series, the higher the number the better. Titan cards for MAXIMUM OVERDRIVE! Coding: quick processor for lots of small tasks. Ergonomic peripherials? - Dear god please dont use a mechanical keyboard so that your coworkers dont kill you. Home office: Everything can be a few gens behind so you can get the best power per dollar spent. - Sorry that Gateway doesnt exist anymore. I guess try Dell... 
Parts (Expensive Legos)
CPU (tells things to go places and outputs data) Basically three main routes to go for: Intel, AMD, or ASIC. Intel - Gaming, Data center, Hackintosh Pros: Cooler, Faster speed (GHZ), short small tasks faster Cons: $$$$, less cores AMD - Gaming, Personal Computing, Large task processing Pros: Lots of cores, better price per performance, faster processing of large tasks Cons: Hot chips, large chips?, compatibility issues with MacOS. ASIC - "Application-specific integrated circuit" Pros: Does the task that they are made to do insanely efficently, great for mining. Cons: Literally does nothing else. Holy hell these are expensive, very hot (fans will get loud) CPU Cooler (Im a big fan) Most come with an in box cooler that are ok but please buy aftermarket. In Box - the free shitty cooler that comes with the processor. Pros: Free. Cons: Ugly, makes chip run hot, hard to clean Air cooler - oldest type of cooler but new designs are highly efficent. Pros: Only cooler that has the possibility of being 100% quiet, most likely cheaper Cons: large, if cooler isnt large enough for the chips thermal output the fans will be loud. Liquid - Custom pipes are beautiful, AIO is easy to install and offers similare performance. Pros: Looks cool, great temperatures, "quiet" Cons: Water pump has possibility of being loud, possible spills Phase Change - uses the technology of refridgerators to cool the chip Pros: Can overclock until the chip breaks. (whats colder than cold? ICE COLD!) Cons: Loud (compressor noise), Large pipes, just why.... Motherboard (the convienacnce store of computer parts) Really just about what type of I/O you want. - MAKE SURE FORM FACTOR FITS YOUR CASE! (or vice versa) - Look for PCI lanes for expansion. - How many graphic cards do you have? - PCI based interfaces? - PCI SSD? - PCI DAC? - PCI WIFI? - USbs? Network? Audio? - How many lanes of RAM? - DOES IT FIT YOUR PROCESSOR!?! (really tho) - M.2? - How many sata interaces? Good Brands: MSI, ASUS, Gigabyte Bad Brands: AS(s)Rock, Dell Memory (Dory) - The more the merrier - No less than 8gb for a functional windows machine (16 gb to never have a problem) - Use all the lanes your computer has to offer! the more lanes to access the faster the data can travel! -Imagine drinking a milkshake. If the straw is wider you can drink more of the milkshake than a skinny straw. - Faster MHZ for faster data access but give minimal performance differances - Please get ram with heat spreadders unles youre building a server with high airflow. - Make sure the type (DDR3 or DDR4) of RAM matches what your processomotherboard call for. Good Brands: Corsair, G.Skill, Ballistix Storage (Grandpa that remembers everythign about how things used to be but takes forever to learn a new tasK) Speed or massive storage? slower is cheaper. Golden ratio of speed/storage/price is 250-500 gb SSD and a 1+ tb disk drive. *Max speeds listed are for a single drive not RAID* Hard Disk Drives (HDD) - Cheapest and slowest - read/write speeds of < 0.5gb/s - 7200+ RPM or GTFO - Higher Speed drives can access data faster. - Do not move while powered up. physical parts will break. - Larger Cahche = faster Read/Write Speeds Pros: Cheap, Holds massive amounts of data Cons: Slower than molasses in a frezer Reputible Brands: Seagate, WD Solid State Drives (SSD) - necessity for quick boots and fast load screens (can only be re-written to so many times) - SATA based (2.5 inch)- Read/Write speeds capped @ 6 gb/s Pros: Most economical, form factor fits with old computers, Cons: "Slow" compared to other ssd's (but stil 12 times faster than a HDD) - M.2 based - Read/Write speeds capped @ 10 gb/s Pros: Size of a sick of gum! High End but not too expensive to be out of reach. Cons: Expensive for any size over 500 gb - PCI based - Read/Write speeds capped @ 20 gb/s for PCI3, x4 Pros: HOLY BANDWIDTH BATMAN! Faster than that little creepy ghost thats always in the corner of you eye Cons: You might have to take out a loan to buy one. *takes up a x4 PCI Lane* Reputible Brands: Samsung! Corsair, Plextor, Intel, Kingston, Crucial Video Card (that one kid that has thick glasses and is really good at math) - A regular old PCI card that handles all of the video rendering and output for your computer. - ASIC PCI cards. - The PCBs and chips are patented by two main companies but the differances come from line up and varying manufacturer cooling devices. - The more memory the better -NVIDIA (Team Green) Great for gaming, has specific card series for intensive rendering. Lazy driver updates. - Gaming - 900 series - Cheap - Low performance - Can play any video game made befrore 2010 on max settings - 1000 (ten) series - Expensive (thanks bitcoin miners...) - Great for VR! - Video Rendering -Quadro Series - Gaming and Rendering - Titan X - Maxwell based chip same as 900 series cards - Titan XP - Pascal based chip same as 10 series cards -AMD (Team Red) Underdog does the same thing but slighly worse and cheaper. (except video rendering) - Gaming - RX 400 series - Cheap - Hot - RX 500 series - Cheap - Ok at VR and deacent gaming frame rates. - Not bad but not particularly great either. - Video Rendering - Fire Pro series - Gaming and Rendering - Vega series -Good luck finding one to buy lmao Case (Fancy clothing for your parts!) - Similar to human clothing you want it to do a few main things really well with compromises for each extreme. - Durability - Steel - Incredibly durable - Creates Farady cage for components - Heavy af - Magnets, just magnets.... - Rust over time - Aluminium - Light - East to bend for modding or "physical maintenance" - Less likely to rust - Huzzah for Farady cages! - Plastic - Just dont - no electrical Ground - no faraday cage - Light AF! - Breath (Airflow) - positive internal airflow! - larger fans push the same amount of air with less speed/noise - Looks - Window? - RGB - Cool Paint? - Fit all your parts - graphics card length/ clearacne - support for liquid cooling raiators? - How many spots for HDD/SSDs - Motherboard format - Cable management! Power Supply (FIGHT MILK) - Rule of thumb: BUy Powersupply that outputs 1.5 times the wattage that you need. - You can walk further than you can you can run. - The PSU can casually output 50-75% power for much longer than at 90-100% (without failure) - If you never demand enough wattage for it to get hot the fan doesnt have to turn on therefore making it quieter. - Modular means you can remove/replace the cables from the PSU. Reputible Brands: Corsair, EVGA Optical Drive (motorized cup holder) - You can download most things today so I'd suggest against it unless you really NEED to watch/write DVD's/CD's Operating System (software that makes everything work) Windows (Always Updates) - Compatible with just about everything - Easy to learn to code on! - POS inital browser - Likely to get virus's Linux (Penguins are cute) - Unique - takes less resources to run - Barebones - Incredibly personalizable! - Compatibility issues with just about everything MacOS (Linux but more annoying) - It is legal! - Great for art and your grandma that doenst know how to use computers! - User friendly - Compatibility issues with various hardware - Confusing/Limiting coding structure Peripherials (cables everywhere!) - Keyboard (higer Polling rate is better) - Mechanical (key is pressed at an exact stroke length every time - Mouse (Higher Polling rate is better) - more buttons = better? - DPI (Dots Per Inch) - In theory, if a mouse has 1600 DPI, then, if you move your mouse one inch (2.54 cm), the mouse cursor will move 1600 pixels - Higher DPI the faster your cursor is able to be moved. - Monitor - In theory the human eye cant see faster than 60 frames per second. - Keep in mind Pixel ratio! - 4k screen that is 22inches will have more pixels in a square inch than a 4k screen that is 28 inches. - Interface? - DVI (Analog) - thumbscrews..... - can do two monitors with one port! - support for 4k - VGA (Analog) - thumbscrews... - max resolution is 1440p - Display Port (digital) - nice button clip - supports 4k - HDMI (Digital) - 1.2 or higer supports 4k - DAC/Speakers/Headphones - Dont even get me started - Microphone - Dont get me started PT.2 Other (other) - UPS (uninterruptible power supply) Just a battery that allows your computer to have some time if the power ever goes out so that you have time to save your work. - Cable Organization materials! - Zipties - velcro - LED LIGHTING! - Manditory - Extra/Better fans - More pressure, less woosh - IFIXIT Pro Tech Toolkit - becasue who buys just one torx wrench. - Cute kitten mousepad - Yes, it has to be a cat.

New people please read this. [upvote for visibility please]

I am seeing too many new people come and and getting confused. Litecoin wiki isn't the greatest when it comes to summing up things so I will try to do things as best as I can. I will attempt to explain from what I have learned and answer some questions. Hopefully people smarter than me will also chime in. I will keep this post updated as much as I can.
Preface
Litecoin is a type to electronic currency. It is just like Bitcoin but it there are differences. Difference explained here.
If you are starting to mine now chances are that you have missed the Bitcoin mining train. If you really want your time and processing power to not go to waste you should mine LTC because the access to BTC from there is much easier.
Mining. What is it?
Let's get this straight. When making any financial commitment to this be prepared to do it with "throw away" money. Mining is all about the hashrate and is measured in KH/s (KiloHash/sec). Unlike the powerful ASICs (Application Specific Integrated Circuit) that are used to mine bitcoins using hashrates in the GH/s and even TH/s, litecoin mining has only been able to achieve at the very best MH/s. I think the highest I've seen is 130 MH/s so far. Which leads us to our next section.
Mining Hardware
While CPU mining is still a thing it is not as powerful as GPU mining. Your laptop might be able to get 1 a month. However, I encourage you to consult this list first. List of hardware comparison You will find the highest of processors can maybe pull 100 KH/s and if we put this into a litecoin mining calculator it doesn't give us much.
Another reason why you don't want to mine with your CPU is pretty simple. You are going to destroy it.
So this leaves us with GPUs. Over the past few months (and years) the HD 7950 has been the favourite because it drains less power and has a pretty good hashrate. But recently the introduction of the R9 290 (not the x) has changed the game a bit. People are getting 850 KH/s - 900 KH/s with that card. It's crazy.
Should I mine?
Honestly given the current difficulty you can make a solid rig for about $1100 with a hashrate of 1700 KH/s which would give you your investment back in about a month and a half. I am sure people out there can create something for much cheaper. Here is a good example of a setup as suggested by dystopiats

Hardware Fundamentals
CPU - Do you need a powerful CPU? No but make sure it is a decent one. AMD CPUs are cheap to buy right now with tons of power. Feel free to use a Sempron or Celeron depending on what Motherboard you go with.
RAM - Try to get at least 4 GB so as to not run into any trouble. Memory is cheap these days. I am saying 4 GB only because of Windoze. If you are plan to run this on Linux you can even get away with less memory.
HDD Any good ol 7200 RPM hard drive will do. Make sure it is appropriate. No point in buying a 1TB hard drive. Since, this is a newbie's guide I assumed most won't know how to run linux, but incase you do you can get a USB flash drive and run linux from it thus removing the need for hard drive all toghether. (thanks dystopiats)
GPU - Consult the list of hardware of hardware I posted above. Make sure you consider the KH/s/W ratio. To me the 290 is the best option but you can skimp down to 7950 if you like.
PSU - THIS IS BLOODY IMPORTANT. Most modern GPUs are power hungry so please make sure you are well within the limits of your power consumption.
MOTHERBOARD - Ok, so a pretty popular board right now is Gigabyte GA-990FXA-UD3 and the ASRock 970 Extreme4. Some people are even going for Gigabyte GA-990FXA-UD5 and even the mighty Gigabyte GA-990FXA-UD7 because it has more PCI-E slots. 6 to be exact. However you may not need that much. With risers you can get more shoved into less.
PCI-E RISERS - These are called risers. They come in x16 to x16 and x1 to x16 connections. Here is the general rule of thumb. This is very important. Always get a POWERED riser otherwise you will burn a hole in your MoBo. A powered rise as a molex connector so that additional power from PSU can be supplied.
When it comes to hardware I've provided the most basic knowledge you need. Also, take a look at cryptobader's website. This is very helpful. Please visit the mining section of Litecoin Forums and the litecoinmining subreddit for more indepth info.
Mining Software
Now that you have assembled your hardware now you need to get into a pool. But before you do that you need a mining software. There are many different ones but the one that is most popular is cgminer. Download it and make sure you read the README. It is a very robust piece of software. Please read this if you want to know more. (thanks BalzOnYer4Head)
Mining Pools
Now that your hardware and software is ready. I know nothing about solo mining other than the fact that you have to be very lucky and respectable amount of hashing power to decrypt a block. So it is better to join pools. I have been pool hopping for a bit and really liked give-me-coin previously known to the community as give-me-ltc. They have a nice mobile app and 0% pool fees. This is really a personal preference. Take a look at this list and try some yourself.
How do I connect to a pool?
Most pools will give you a tutorial on how to but the basics are as follows:
  • Signup for a pool
  • Create a worker for your account. Usually one worker per rig (Yes people have multiple rigs) is generally a good idea.
  • Create a .run file. Open up notepad and type cgminer.exe -o (address_to_the_miningpool:port_number) -u (yourusername.workername) -p (your_worker_password_if_you_made_one). Then File>Save As>runcgminer.run (Make sure the drop down is set to "All Files" and .txt document.) and save in the same folder as cgminer. That's it.
  • Double click on runcgminer.run (or whatever you named it) and have fun mining.
Mining Profitability
This game is not easy. If it was, practically everyone would be doing it. This is strictly a numbers game and there are calculations available that can help you determine your risk on your investments. 4 variables you need to consider when you are starting to mine:
Hardware cost: The cost of your physical hardware to run this whole operation.
Power: Measured in $/KwH is also known as the operating cost.
Difficulty rate: To put it in layman's terms the increase in difficulty is inversely proportional to amount of coin you can mine. The harder the difficulty the harder it is to mine coin. Right now difficulty is rising at about 18% per 3 days. This can and will change since all you miners are soon going to jump on the band wagon.
Your sanity: I am not going to tell you to keep calm and chive on because quiet frankly that is stupid. What I will tell you not to get too carried away. You will pull you hair out. Seriously.
Next thing you will need is a simple tool. A mining profitability calculator. I have two favourite ones.
coinwarz
I like this one cause it is simple. The fields are self explanatory. Try it.
bitcoinwisdom
I like this one because it is a more real life scenario calculator and more complicated one (not really). It also takes increasing difficulty into account.
Please note: This is the absolute basic info you need. If you have more questions feel free to ask and or google it!

FOR IMMEDIATE RELEASE: After Butterfly Labs collapses, engineers find new jobs at 21 Inc.

BEGIN BLOG POST

After Butterfly Labs collapses, engineers find new jobs at 21 Inc.

A bitcoin miner has shipped on time. Yes, that is news. A new venture-capital backed company, 21 Inc., has released a miniature bitcoin miner that they call a "Bitcoin computer". For $399.99, you get a Raspberry Pi, an SHA-256 ASIC board, and a giant fan.
Again, this is news: normally, a manufacturer of bitcoin miners would overdesign and underengineer their equipment, or, if they managed to ship something functional, it would be so poorly engineered -- and over budget -- that it be an explosion waiting to happen and/or priced comparably to a four-door sedan.
21 Inc. has done something remarkable in the Bitcoin world: they started a company that operates like a legitimate business. They're even listed on Amazon.com, a company that's so strict with vendors that Nintendo was kicked off their system for not kissing enough customer ass.
Okay, enough with the praise.

This thing sucks.

The 21.co "computer" certainly deserves a place in the VC world, along with the other products consisting of wild promises and inane use cases. For the price of 4 Raspberry Pi computer kits, you get the following:
(If you have a remote desire to develop applications that use bitcoin, stop here. Go through that list and buy just those items above. You don't need anything else. If you're looking for comedy, or if you're a sucker with too much money, read on...)

Is that all I get for my money?

Those products alone don't allow you to make Bitcoin applications, apparently. You need these things, too:

How about the software demos?

It's difficult to justify developing a $400 computer that can't do much. So, to entice some customers, 21 Inc. included demos that try really hard to make customers feel inspired. Here are just a few things that 21 Inc. claims were totally impossible before their product existed:

What are the real customers saying?

The packaging is slick:
"This @21dotco computer came already opened..."
The hardware is reliable:
"...it must have lost power, which caused my SSH keys to become corrupted."
The software is revolutionary:
"...it will be more expensive to pay for your spotify subscription via your electricity bill, but a lot of people don't care."

I want to buy it anyway!

Go ahead. I won't stop you. Oh, and 21 Inc. doesn't accept bitcoins.

My first 30 days running a Bitcoin only E-commerce business.

The MineNinja store, www.mineninja.com, has been up for a month now, so I figure its a good time to reflect on the whole experience of running a business that accepts Bitcoin exclusively. I’ve run other E-commerce websites, mainly selling digital products for PayPal. In my previous experiment I tried adding Bitcoin payment to one of my best performing products and honestly got less than stellar results even offering a huge discount.
After studying the market I determined that a better path was to offer a product that would appeal to one of the core segments of the Bitcoin participant population: Bitcoin miners. The MineNinja is a Bitcoin mining controller for managing USB connected ASIC devices.
I underestimated how difficult the whole process would be from manufacturing to shipping. The first few orders were very painful to fulfill. There were many late nights spent trying to dial in the packaging and shipping. 3d took some time to get dialed in correctly, and we threw away a ton of failed prints. It was a great learning experience.
I also learned that keeping everything denominated in Bitcoin is risky. When the price of Bitcoin fell, and I didn’t update my pricing quick enough, we had sales that resulted in a net loss. I could eliminate this risk by pricing in USD, but it’s a matter of principle to keep it all Bitcoin.
I didn’t do any sort of advertising, no Adwords or anything like that. All I have done is just a few posts on bitcoin and Bitcoin related forums. I did a total of 28BTC worth of sales for the first month.
Expenses:
Startup Investment - 3D printer: $2195
Cost of Goods Sold:
The USD denominated supplies were personally funded. I am trying to keep all the BTC earnings in BTC. I am moving my supply chain to Bitcoin as practical. I found a cool 3d Printer company www.makergeeks.com that accepts Bitcoin payments so next month’s personal finances will be a little better. I’m still having to pay USD to buy the boards as I have not yet found a supplier that accepts Bitcoin payment.
I don’t think my decision to go with a completely open source solution hurt sales too badly. Most customers chose the more expensive ready-to-mine options over the build-your-own. I got hit hard for BeagleBones when the BTC price dropped, and I didn’t adjust prices, but thankfully my low inventories and a recent rebound in price insulated me from disaster.
Now that I have shut down my GPUs, I can move the business from the dining room table to the room we now refer to as the "crap room." The big weekend project is to clean it out and convert it into the CoinNinja headquarters.
I’ve got quite a few cool things planned for the MineNinja project and other CoinNinja Open Source projects. Stay tuned.

Bitcoin Mining Profits: Crypto Mining Hardware or Cloud Mining Pools?

Can Cloud Mining Be More Profitable Than Getting Mining Hardware For Bitcoin?
The process of crypto mining demands a lot of preparation, no matter which cryptocurrency you choose. Mining Bitcoin (BTC), however, requires even more.
If you are a Bitcoin miner, or you at least researched the issue, you probably quickly realized that this is quite a difficult process. There a lot of aspects of the process that need to be considered, like the Proof-of-Work’s mining algorithm, fees, and hashing power. Not to mention the extremely expensive equipment that is necessary in order to do it.
However, there is another option which may be more profitable, and that is cloud mining. But is it really the best way to go? Let us find out.
Bitcoin Miningining: Hardware & Cost
Let’s start with the necessary mining hardware. In order to mine Bitcoin, you cannot just use anything, and in order to get a quality device, you will have to prepare quite a sum in advance.
Bitcoin mining hardware can cost from a few thousand dollars to tens of thousands of dollars. The price largely depends on which crypto you wish to mine (in this case, Bitcoin), as well as how big of a mining operation you are planning.
The cost of a mining rig depends on which one you want. You might go for an ASIC mining rig, or a GPU and CPU mining rigs. ASIC mining rig is usually far more expensive, and their hash rates are a lot faster. However, they are known for facing scrutiny due to the fact that you cannot repurpose them.
Basically, if the hash algorithm of the blockchain changes, your ASIC rig will become pretty much useless, and you will have to acquire new gear. Obviously, this is the most expensive solution.
GPU and CPU gear, on the other hand, can be re-purposed. The gear is also a lot cheaper, and much more acceptable than ASIC, which often finds a lot of resistance. This is why most miners choose to go for GPU and CPU instead of ASIC.
Of course, there is always an option to have several mining rigs set up, in order to multiply your earnings. However, this means that you will have to acquire them first, which is probably the most expensive option. Even with several mining rigs working at the same time, it will probably take months before you can cover these initial costs via mining. Not to mention other factors, like the cost of an electric bill that is going to skyrocket as soon as you start your mining operation.
The electricity cost varies depending on your location, which makes it hard to precisely calculate the cost of keeping the operation up and running.
Cryptocurrency Cloud Mining Pools: Profitable or Not?
Calculating the costs of cloud mining, on the other hand, is a much easier process. A lot of companies are using monthly subscriptions, with their cost being determined by the targeted crypto that the user wants to mine. Additionally, the cost of the model is also determined by the hash rate speeds.
For example, taking a contract for 2 years of mining Ethereum with Genesis Mining can cost anywhere between $1,520 and $12,960, depending on the speed which can go from 40 MH/s to 360 MH/s.
On the other hand, there is a website called HashFlare, which can provide you with a contract that lasts only one year, and it costs $1.80 for 100 KH/s.
The fact is that cloud mining is expensive as well, and not that profitable at first. You will probably need more than a year to cover the cost of the initial investment. A lot of people don’t do their research properly, which is why they enter the process expecting to get rich in less than 6 months. This is, of course, never the case.
Generally, cloud mining is not that profitable at all. Because of that, it is also not the popular way of crypto mining. Monthly subscriptions will always be there, but it won’t always be easy to pay them off. There are always the USB mining options but they are not very powerful.
If you choose to go with the mining hardware, the costs will be upfront, and you will know what you are getting into. The cost of electricity will be a bit more difficult to predict, but if you can afford to perform your mining operation in parts of the world where the electricity is cheap, and mining is legal, you can actually make a pretty good profit much faster.

USB ASIC Miner 5GH/s

Hi Everyone,
Im new to mining and have been playing around with using my GPU in my home computer. Which gets a terrible hashrate, between 40-50 MH/s. I've been mining through guiminer and slushpool so far as well.
Im curious about the 5GH/s USB ASIC miners from Butterfly labs. Has anyone used one? Will the 5GH/s have a worthy return?
Also looking to get some feed back on using one of these for pool mining.
Any feedback in general on these devices would be appreciated before I send off almost $300. Even if there are better USB ASIC miners for the price.

mining with ATI Radeon HD 5700 series

I have been getting into the bitcoin frenzy finally and started looking into ways in which I can start out. I'm not the usual n00b since I have everything up and working. Only thing that I am having problems with are the performance issues. I have my Catalyst drivers installed and running and the Radeon is working like it should but at a lower speed than I expected from what I have read about others using this same card series. When I use guiminer with the slush pool, I get at least 80 kH/s, when mining litecoin with guiminer scrypt, I get more performance at 200 kH/s. both less than what I had expected. This is all in windows. When I give it a go in Linux with cgminer, the program doesn't even see the card, apparently it seems to be checking the usb hub instead of rhe PCI and PCI express ports. Is there a way to make cgminer look into the pci slots instead of only checking the usb ports. I can always use a USB asic miner from a company like butterfly labs but I have heard not only negative feedback about not only the performance but also the price in which they are sold for and how it's time consuming to get it to pay you back the extremely large amount of money that you spent on them in the first place. Can I get my Radeon card to mine faster in windows, and how can I get it recognized in Linux by cgminer. This is getting really frustrating, and bitcoin jobs are more competitive than actual jobs. If it's relavent, I only get internet bandwith at 2Mb/s which i think is a major contributing factor but I've been told it isn't.

My experience with Bitcoin: How I lost $5k and a potential profit for over $42k.

Happy Dec 1 everyone.
I can't sleep tonight and I have something to get off my chest, so story time.
I got into bitcoin soon after the crash in April. I was very interested in bitcoin and the way it worked and finally decided to buy when the price was around $105-$125 range. I spend $5k total and got around 42btc. That $5k was my life savings but I believed bitcoin was the future. At this time I was still working at my minimum wage job and barely getting by. I wanted a way out of my horrible existent. I wanted to go to school again but I was too worried about paying my bills or if I was going to make it the next month. I thought bitcoin was my way out. I was inspired by the stories of the people that "forgot" their wallet and all of a sudden they were tens or hundred-thousandaires.
While I was doing research I stumbled upon the bitcoin forums bitcointalk.org. I thought about mining bitcoin but didn't have the hardware. I don't have an awesome rig that can and I couldn't afford the asic units that butterfly labs were selling away. After a few weeks I learned that butterfly labs were not to be trusted and asicminer announced they we selling the usb miners. At this time the general consensus was that mining will never be profitable but I bought some anyway with the plans of reselling it. I got into bitcoin stocks because of asicminer. I have a few shares at the time and eventually got more and reinvested the dividends into the 1/100 asicminer. At this time things were looking up. I had a usb miner hashing away and asic miner was going up in price.
After a few weeks I sold my usb miners on ebay and got a good deal on it. I went over my breakeven point and had extra money. So I used the USD to buy more bitcoin with bitinstant. Bitinstant has a meltdown and didnt get my btc in time to reinvest in asicminer. The price shot up to 2.5btc a share and I missed out but it was ok. This is the high point of my life and experience with bitcoin. The dividends from asicminer was helping me pay some of my bills. I had a great investment going and I was richer than I had ever been. Bitcoin was my savior. Bitcoin was my answer. I got so excited about it I told my parents but they were disenchanted. I was met with "Why do you always daydream? Why can't you just go to school and get a real job? Imaginary money, fake money, scam." I'm not that smart so its hard for me to go to college but everyone keeps telling me you have to go to school to get a good job.
Well the next month came and ebay hit me with a 10% fee for successfully selling my stuff. I didn't know about the fee so I was caught off guard and now my bank account is in the negative. I didn't eat for the next few days while I was waiting for my bitcoins to turn into USD and transfer to my account.
I have been spending a lot of time lurking bitcointalk.org and there was news of these new start ups. BTCgarden and Labcoin. I was thinking I'll show my parents that I'm not daydreaming, I'm going to make it big and they won't be disappointed. So I sold all my asicminer shares and had around 90btc all together. I split between the two and when BTCgarden failed I dump the rest into Labcoin. Asicminer was falling in price at this time and I was glad I made it move. At the height of Labcoin I had over 150BTC. I thought I made it. I was happy. The next day burnside [stock exchange operator] announced he was going to close down his exchange and the price for everything plummeted. I didn't find out until a few days later when I was my stocks were worth 1/6 of what they worth. I was destroyed, I didn't know what to do and I was drinking the Labcoin cool-aid hard. I thought that its ok, the price will go back to IPO and I can sell. Months pass and I lost my job. I couldn't focus at work and I was really pissy. Now I'm sitting on useless Labcoin shares and joined with the group of people looking for a lawsuit, knowing full well I'll never get my money back. I lost my apartment last week and I had to go home with my parent (who are rubbing this shit in my face every chance they get. That is the reason why I moved out in the first place). I had the worst thanksgiving ever and I'm not looking forward for Christmas or the New Years. Its hard trying to find a job. I don't know what to do anymore. Its killing me that bitcoin is over $1k. If I had just kept it in my wallet and didn't touch it I would have over $40k now. Hindsight is a bitch.
Thanks for listening. I hope you guys have a better time with bitcoin.
TL;DR: This is not a bitcoin success story. Its a story about my highs and lows and ultimately my failure.
