Blockchain Bites: Dorsey Challenges Coinbase, Nasdaq Lists Diginex, Ethereum Miners Profit
The Australian government is investing big in modern technology, Nasdaq saw its first crypto exchange operator listing and revenues are surging for Ethereum miners amid increased network activity.
Australia modernizes Australia will commit A$800 million (US$575 million) to invest in digital technologies as part of its coronavirus recovery plan, Prime Minister Scott Morrison announced Tuesday. The federal plan will see US$256.6 million for a digital identity solution, $419.9 million to fully implement the Modernising Business Registers (MBR) program, $22.2 million for small businesses training to utilize digital technologies and two blockchain pilot programs totalling $6.9 million. “The Plan supports Australia’s economic recovery by removing out-dated regulatory barriers, boosting the capability of small businesses and backs the uptake of technology across the economy,” Morrison said in the announcement.
Nasdaq launch Blockchain services firm Diginex has become the first crypto exchange operator to list on Nasdaq. The stock went live Thursday morning under the EQOS ticker symbol, a nod to the firm’s EQUOS.io trading platform. CoinDesk’s Nathan DiCamillo reports Diginex’s back-door listing came through a merger with a special-purpose acquisition company (SPAC). Diginex CEO Richard Byworth said he expects a mix of global retail and institutional investors to buy shares. Over time, he expects the majority of Diginex shareholders to be U.S. investors because of the Nasdaq listing.
Dorsey responds Twitter CEO Jack Dorsey tweeted his disapproval of Coinbase CEO Brian Armstrong’s mission statement to keep his company free and clear of politics. Dorsey argued that by the very act of being a crypto exchange, Coinbase was always already engaged in politics. “Bitcoin (aka ‘crypto’) is direct activism against an unverifiable and exclusionary financial system which negatively affects so much of our society. Important to at least acknowledge and connect the related societal issues your customers face daily. This leaves people behind,” Dorsey tweeted. Armstrong made waves this week – in and out of crypto – when saying Coinbase, and its employees, should keep work and activism separate.
Election predictions Putting stake to their claims, many crypto-political gamblers have cast their vote predicting who might win the contentious U.S. presidential election. CoinDesk markets editor Lawrence Lewitinn looked at the data following this week’s first presidential debate and found many are betting incumbent President Donald Trump will lose in November. While bettors on decentralized betting platforms like Augur and futures markets on FTX aren’t as bullish on the challenger, former Vice President Joe Biden, he does have the odds. “Thus what’s true at the time of publication can change on a dime. It is now fewer than five weeks until Election Day. Buckle up!” Lewitinn warns.
Mining profits HIVE Blockchain has reported its best-ever quarter, as the mining firm raked in record fees from the frenzied activity in decentralized finance (DeFi) over the summer. The Toronto-listed mining company released its unaudited results Thursday, saying it mined a total of 32,000 ether (ETH) and 121,000 ethereum classic (ETC) in the second fiscal quarter ending Sept. 30. Per CoinDesk’s price data, that comes to nearly $11.8 million for mining ether, and a further $664,000 for ethereum classic – approximately $12.4 million at time of writing. The figures represent a near 30% increase from the 25,000 ETH that HIVE mined in the first quarter and a 50% increase in the same quarter in 2019.
Stealth launch In the latest effort to smooth a path for buttoned-up investors, Talos, an institutional-grade conduit to the crypto ecosystem, is emerging from stealth mode to serve brokers, custodians, exchanges and over-the-counter (OTC) trading desks. The platform started out in 2018 and is backed by an impressive list of investors including Autonomous Partners, Castle Island Ventures, Coinbase Ventures and Initialized Capital. Over the past year or so, Talos has been quietly onboarding a core group of capital market participants, so that the platform can make its debut in a revenue-generating state.

Technical: A Brief History of Payment Channels: from Satoshi to Lightning Network

Who cares about political tweets from some random country's president when payment channels are a much more interesting and are actually capable of carrying value?
So let's have a short history of various payment channel techs!

Generation 0: Satoshi's Broken nSequence Channels

Because Satoshi's Vision included payment channels, except his implementation sucked so hard we had to go fix it and added RBF as a by-product.
Originally, the plan for nSequence was that mempools would replace any transaction spending certain inputs with another transaction spending the same inputs, but only if the nSequence field of the replacement was larger.
Since 0xFFFFFFFF was the highest value that nSequence could get, this would mark a transaction as "final" and not replaceable on the mempool anymore.
In fact, this "nSequence channel" I will describe is the reason why we have this weird rule about nLockTime and nSequence. nLockTime actually only works if nSequence is not 0xFFFFFFFF i.e. final. If nSequence is 0xFFFFFFFF then nLockTime is ignored, because this if the "final" version of the transaction.
So what you'd do would be something like this:
  1. You go to a bar and promise the bartender to pay by the time the bar closes. Because this is the Bitcoin universe, time is measured in blockheight, so the closing time of the bar is indicated as some future blockheight.
  2. For your first drink, you'd make a transaction paying to the bartender for that drink, paying from some coins you have. The transaction has an nLockTime equal to the closing time of the bar, and a starting nSequence of 0. You hand over the transaction and the bartender hands you your drink.
  3. For your succeeding drink, you'd remake the same transaction, adding the payment for that drink to the transaction output that goes to the bartender (so that output keeps getting larger, by the amount of payment), and having an nSequence that is one higher than the previous one.
  4. Eventually you have to stop drinking. It comes down to one of two possibilities:
    • You drink until the bar closes. Since it is now the nLockTime indicated in the transaction, the bartender is able to broadcast the latest transaction and tells the bouncers to kick you out of the bar.
    • You wisely consider the state of your liver. So you re-sign the last transaction with a "final" nSequence of 0xFFFFFFFF i.e. the maximum possible value it can have. This allows the bartender to get his or her funds immediately (nLockTime is ignored if nSequence is 0xFFFFFFFF), so he or she tells the bouncers to let you out of the bar.
Now that of course is a payment channel. Individual payments (purchases of alcohol, so I guess buying coffee is not in scope for payment channels). Closing is done by creating a "final" transaction that is the sum of the individual payments. Sure there's no routing and channels are unidirectional and channels have a maximum lifetime but give Satoshi a break, he was also busy inventing Bitcoin at the time.
Now if you noticed I called this kind of payment channel "broken". This is because the mempool rules are not consensus rules, and cannot be validated (nothing about the mempool can be validated onchain: I sigh every time somebody proposes "let's make block size dependent on mempool size", mempool state cannot be validated by onchain data). Fullnodes can't see all of the transactions you signed, and then validate that the final one with the maximum nSequence is the one that actually is used onchain. So you can do the below:
  1. Become friends with Jihan Wu, because he owns >51% of the mining hashrate (he totally reorged Bitcoin to reverse the Binance hack right?).
  2. Slip Jihan Wu some of the more interesting drinks you're ordering as an incentive to cooperate with you. So say you end up ordering 100 drinks, you split it with Jihan Wu and give him 50 of the drinks.
  3. When the bar closes, Jihan Wu quickly calls his mining rig and tells them to mine the version of your transaction with nSequence 0. You know, that first one where you pay for only one drink.
  4. Because fullnodes cannot validate nSequence, they'll accept even the nSequence=0 version and confirm it, immutably adding you paying for a single alcoholic drink to the blockchain.
  5. The bartender, pissed at being cheated, takes out a shotgun from under the bar and shoots at you and Jihan Wu.
  6. Jihan Wu uses his mystical chi powers (actually the combined exhaust from all of his mining rigs) to slow down the shotgun pellets, making them hit you as softly as petals drifting in the wind.
  7. The bartender mutters some words, clothes ripping apart as he or she (hard to believe it could be a she but hey) turns into a bear, ready to maul you for cheating him or her of the payment for all the 100 drinks you ordered from him or her.
  8. Steely-eyed, you stand in front of the bartender-turned-bear, daring him to touch you. You've watched Revenant, you know Leonardo di Caprio could survive a bear mauling, and if some posh actor can survive that, you know you can too. You make a pose. "Drunken troll logic attack!"
  9. I think I got sidetracked here.
Lessons learned?

Spilman Channels

Incentive-compatible time-limited unidirectional channel; or, Satoshi's Vision, Fixed (if transaction malleability hadn't been a problem, that is).
Now, we know the bartender will turn into a bear and maul you if you try to cheat the payment channel, and now that we've revealed you're good friends with Jihan Wu, the bartender will no longer accept a payment channel scheme that lets one you cooperate with a miner to cheat the bartender.
Fortunately, Jeremy Spilman proposed a better way that would not let you cheat the bartender.
First, you and the bartender perform this ritual:
  1. You get some funds and create a transaction that pays to a 2-of-2 multisig between you and the bartender. You don't broadcast this yet: you just sign it and get its txid.
  2. You create another transaction that spends the above transaction. This transaction (the "backoff") has an nLockTime equal to the closing time of the bar, plus one block. You sign it and give this backoff transaction (but not the above transaction) to the bartender.
  3. The bartender signs the backoff and gives it back to you. It is now valid since it's spending a 2-of-2 of you and the bartender, and both of you have signed the backoff transaction.
  4. Now you broadcast the first transaction onchain. You and the bartender wait for it to be deeply confirmed, then you can start ordering.
The above is probably vaguely familiar to LN users. It's the funding process of payment channels! The first transaction, the one that pays to a 2-of-2 multisig, is the funding transaction that backs the payment channel funds.
So now you start ordering in this way:
  1. For your first drink, you create a transaction spending the funding transaction output and sending the price of the drink to the bartender, with the rest returning to you.
  2. You sign the transaction and pass it to the bartender, who serves your first drink.
  3. For your succeeding drinks, you recreate the same transaction, adding the price of the new drink to the sum that goes to the bartender and reducing the money returned to you. You sign the transaction and give it to the bartender, who serves you your next drink.
  4. At the end:
    • If the bar closing time is reached, the bartender signs the latest transaction, completing the needed 2-of-2 signatures and broadcasting this to the Bitcoin network. Since the backoff transaction is the closing time + 1, it can't get used at closing time.
    • If you decide you want to leave early because your liver is crying, you just tell the bartender to go ahead and close the channel (which the bartender can do at any time by just signing and broadcasting the latest transaction: the bartender won't do that because he or she is hoping you'll stay and drink more).
    • If you ended up just hanging around the bar and never ordering, then at closing time + 1 you broadcast the backoff transaction and get your funds back in full.
Now, even if you pass 50 drinks to Jihan Wu, you can't give him the first transaction (the one which pays for only one drink) and ask him to mine it: it's spending a 2-of-2 and the copy you have only contains your own signature. You need the bartender's signature to make it valid, but he or she sure as hell isn't going to cooperate in something that would lose him or her money, so a signature from the bartender validating old state where he or she gets paid less isn't going to happen.
So, problem solved, right? Right? Okay, let's try it. So you get your funds, put them in a funding tx, get the backoff tx, confirm the funding tx...
Once the funding transaction confirms deeply, the bartender laughs uproariously. He or she summons the bouncers, who surround you menacingly.
"I'm refusing service to you," the bartender says.
"Fine," you say. "I was leaving anyway;" You smirk. "I'll get back my money with the backoff transaction, and posting about your poor service on reddit so you get negative karma, so there!"
"Not so fast," the bartender says. His or her voice chills your bones. It looks like your exploitation of the Satoshi nSequence payment channel is still fresh in his or her mind. "Look at the txid of the funding transaction that got confirmed."
"What about it?" you ask nonchalantly, as you flip open your desktop computer and open a reputable blockchain explorer.
What you see shocks you.
"What the --- the txid is different! You--- you changed my signature?? But how? I put the only copy of my private key in a sealed envelope in a cast-iron box inside a safe buried in the Gobi desert protected by a clan of nomads who have dedicated their lives and their childrens' lives to keeping my private key safe in perpetuity!"
"Didn't you know?" the bartender asks. "The components of the signature are just very large numbers. The sign of one of the signature components can be changed, from positive to negative, or negative to positive, and the signature will remain valid. Anyone can do that, even if they don't know the private key. But because Bitcoin includes the signatures in the transaction when it's generating the txid, this little change also changes the txid." He or she chuckles. "They say they'll fix it by separating the signatures from the transaction body. They're saying that these kinds of signature malleability won't affect transaction ids anymore after they do this, but I bet I can get my good friend Jihan Wu to delay this 'SepSig' plan for a good while yet. Friendly guy, this Jihan Wu, it turns out all I had to do was slip him 51 drinks and he was willing to mine a tx with the signature signs flipped." His or her grin widens. "I'm afraid your backoff transaction won't work anymore, since it spends a txid that is not existent and will never be confirmed. So here's the deal. You pay me 99% of the funds in the funding transaction, in exchange for me signing the transaction that spends with the txid that you see onchain. Refuse, and you lose 100% of the funds and every other HODLer, including me, benefits from the reduction in coin supply. Accept, and you get to keep 1%. I lose nothing if you refuse, so I won't care if you do, but consider the difference of getting zilch vs. getting 1% of your funds." His or her eyes glow. "GENUFLECT RIGHT NOW."
Lesson learned?

CLTV-protected Spilman Channels

Using CLTV for the backoff branch.
This variation is simply Spilman channels, but with the backoff transaction replaced with a backoff branch in the SCRIPT you pay to. It only became possible after OP_CHECKLOCKTIMEVERIFY (CLTV) was enabled in 2015.
Now as we saw in the Spilman Channels discussion, transaction malleability means that any pre-signed offchain transaction can easily be invalidated by flipping the sign of the signature of the funding transaction while the funding transaction is not yet confirmed.
This can be avoided by simply putting any special requirements into an explicit branch of the Bitcoin SCRIPT. Now, the backoff branch is supposed to create a maximum lifetime for the payment channel, and prior to the introduction of OP_CHECKLOCKTIMEVERIFY this could only be done by having a pre-signed nLockTime transaction.
With CLTV, however, we can now make the branches explicit in the SCRIPT that the funding transaction pays to.
Instead of paying to a 2-of-2 in order to set up the funding transaction, you pay to a SCRIPT which is basically "2-of-2, OR this singlesig after a specified lock time".
With this, there is no backoff transaction that is pre-signed and which refers to a specific txid. Instead, you can create the backoff transaction later, using whatever txid the funding transaction ends up being confirmed under. Since the funding transaction is immutable once confirmed, it is no longer possible to change the txid afterwards.

Todd Micropayment Networks

The old hub-spoke model (that isn't how LN today actually works).
One of the more direct predecessors of the Lightning Network was the hub-spoke model discussed by Peter Todd. In this model, instead of payers directly having channels to payees, payers and payees connect to a central hub server. This allows any payer to pay any payee, using the same channel for every payee on the hub. Similarly, this allows any payee to receive from any payer, using the same channel.
Remember from the above Spilman example? When you open a channel to the bartender, you have to wait around for the funding tx to confirm. This will take an hour at best. Now consider that you have to make channels for everyone you want to pay to. That's not very scalable.
So the Todd hub-spoke model has a central "clearing house" that transport money from payers to payees. The "Moonbeam" project takes this model. Of course, this reveals to the hub who the payer and payee are, and thus the hub can potentially censor transactions. Generally, though, it was considered that a hub would more efficiently censor by just not maintaining a channel with the payer or payee that it wants to censor (since the money it owned in the channel would just be locked uselessly if the hub won't process payments to/from the censored user).
In any case, the ability of the central hub to monitor payments means that it can surveill the payer and payee, and then sell this private transactional data to third parties. This loss of privacy would be intolerable today.
Peter Todd also proposed that there might be multiple hubs that could transport funds to each other on behalf of their users, providing somewhat better privacy.
Another point of note is that at the time such networks were proposed, only unidirectional (Spilman) channels were available. Thus, while one could be a payer, or payee, you would have to use separate channels for your income versus for your spending. Worse, if you wanted to transfer money from your income channel to your spending channel, you had to close both and reshuffle the money between them, both onchain activities.

Poon-Dryja Lightning Network

Bidirectional two-participant channels.
The Poon-Dryja channel mechanism has two important properties:
Both the original Satoshi and the two Spilman variants are unidirectional: there is a payer and a payee, and if the payee wants to do a refund, or wants to pay for a different service or product the payer is providing, then they can't use the same unidirectional channel.
The Poon-Dryjam mechanism allows channels, however, to be bidirectional instead: you are not a payer or a payee on the channel, you can receive or send at any time as long as both you and the channel counterparty are online.
Further, unlike either of the Spilman variants, there is no time limit for the lifetime of a channel. Instead, you can keep the channel open for as long as you want.
Both properties, together, form a very powerful scaling property that I believe most people have not appreciated. With unidirectional channels, as mentioned before, if you both earn and spend over the same network of payment channels, you would have separate channels for earning and spending. You would then need to perform onchain operations to "reverse" the directions of your channels periodically. Secondly, since Spilman channels have a fixed lifetime, even if you never used either channel, you would have to periodically "refresh" it by closing it and reopening.
With bidirectional, indefinite-lifetime channels, you may instead open some channels when you first begin managing your own money, then close them only after your lawyers have executed your last will and testament on how the money in your channels get divided up to your heirs: that's just two onchain transactions in your entire lifetime. That is the potentially very powerful scaling property that bidirectional, indefinite-lifetime channels allow.
I won't discuss the transaction structure needed for Poon-Dryja bidirectional channels --- it's complicated and you can easily get explanations with cute graphics elsewhere.
There is a weakness of Poon-Dryja that people tend to gloss over (because it was fixed very well by RustyReddit):
Another thing I want to emphasize is that while the Lightning Network paper and many of the earlier presentations developed from the old Peter Todd hub-and-spoke model, the modern Lightning Network takes the logical conclusion of removing a strict separation between "hubs" and "spokes". Any node on the Lightning Network can very well work as a hub for any other node. Thus, while you might operate as "mostly a payer", "mostly a forwarding node", "mostly a payee", you still end up being at least partially a forwarding node ("hub") on the network, at least part of the time. This greatly reduces the problems of privacy inherent in having only a few hub nodes: forwarding nodes cannot get significantly useful data from the payments passing through them, because the distance between the payer and the payee can be so large that it would be likely that the ultimate payer and the ultimate payee could be anyone on the Lightning Network.

Future

After LN, there's also the Decker-Wattenhofer Duplex Micropayment Channels (DMC). This post is long enough as-is, LOL. But for now, it uses a novel "decrementing nSequence channel", using the new relative-timelock semantics of nSequence (not the broken one originally by Satoshi). It actually uses multiple such "decrementing nSequence" constructs, terminating in a pair of Spilman channels, one in both directions (thus "duplex"). Maybe I'll discuss it some other time.
The realization that channel constructions could actually hold more channel constructions inside them (the way the Decker-Wattenhofer puts a pair of Spilman channels inside a series of "decrementing nSequence channels") lead to the further thought behind Burchert-Decker-Wattenhofer channel factories. Basically, you could host multiple two-participant channel constructs inside a larger multiparticipant "channel" construct (i.e. host multiple channels inside a factory).
Further, we have the Decker-Russell-Osuntokun or "eltoo" construction. I'd argue that this is "nSequence done right". I'll write more about this later, because this post is long enough.

Market Risk 22. Bitcoin's Tax Risk What is Bitcoin?
Bitcoin is a digital currency created in January 2009. It follows the ideas set out in a white paper by the mysterious Satoshi Nakamoto, whose true identity is yet to be verified. Bitcoin offers the promise of lower transaction fees than traditional online payment mechanisms and is operated by a decentralized authority, unlike government-issued currencies.
There are no physical bitcoins, only balances kept on a public ledger in the cloud, that – along with all Bitcoin transactions – is verified by a massive amount of computing power. Bitcoins are not issued or backed by any banks or governments, nor are individual bitcoins valuable as a commodity. Despite it not being legal tender, Bitcoin charts high on popularity, and has triggered the launch of other virtual currencies collectively referred to as Altcoins.
Understanding Bitcoin Bitcoin is a type of cryptocurrency: Balances are kept using public and private "keys," which are long strings of numbers and letters linked through the mathematical encryption algorithm that was used to create them. The public key (comparable to a bank account number) serves as the address which is published to the world and to which others may send bitcoins. The private key (comparable to an ATM PIN) is meant to be a guarded secret and only used to authorize Bitcoin transmissions. Style notes: According to the official Bitcoin Foundation, the word "Bitcoin" is capitalized in the context of referring to the entity or concept, whereas "bitcoin" is written in the lower case when referring to a quantity of the currency (e.g. "I traded 20 bitcoin") or the units themselves. The plural form can be either "bitcoin" or "bitcoins."
How Bitcoin Works Bitcoin is one of the first digital currencies to use peer-to-peer technology to facilitate instant payments. The independent individuals and companies who own the governing computing power and participate in the Bitcoin network, also known as "miners," are motivated by rewards (the release of new bitcoin) and transaction fees paid in bitcoin. These miners can be thought of as the decentralized authority enforcing the credibility of the Bitcoin network. New bitcoin is being released to the miners at a fixed, but periodically declining rate, such that the total supply of bitcoins approaches 21 million. One bitcoin is divisible to eight decimal places (100 millionths of one bitcoin), and this smallest unit is referred to as a Satoshi. If necessary, and if the participating miners accept the change, Bitcoin could eventually be made divisible to even more decimal places. Bitcoin mining is the process through which bitcoins are released to come into circulation. Basically, it involves solving a computationally difficult puzzle to discover a new block, which is added to the blockchain and receiving a reward in the form of a few bitcoins. The block reward was 50 new bitcoins in 2009; it decreases every four years. As more and more bitcoins are created, the difficulty of the mining process – that is, the amount of computing power involved – increases. The mining difficulty began at 1.0 with Bitcoin's debut back in 2009; at the end of the year, it was only 1.18. As of February 2019, the mining difficulty is over 6.06 billion. Once, an ordinary desktop computer sufficed for the mining process; now, to combat the difficulty level, miners must use faster hardware like Application-Specific Integrated Circuits (ASIC), more advanced processing units like Graphic Processing Units (GPUs), etc.
What's a Bitcoin Worth? In 2017 alone, the price of Bitcoin rose from a little under $1,000 at the beginning of the year to close to $19,000, ending the year more than 1,400% higher. Bitcoin's price is also quite dependent on the size of its mining network since the larger the network is, the more difficult – and thus more costly – it is to produce new bitcoins. As a result, the price of bitcoin has to increase as its cost of production also rises. The Bitcoin mining network's aggregate power has more than tripled over the past twelve months.
How Bitcoin Began
Aug. 18, 2008: The domain name bitcoin.org is registered. Today, at least, this domain is "WhoisGuard Protected," meaning the identity of the person who registered it is not public information.
Oct. 31, 2008: Someone using the name Satoshi Nakamoto makes an announcement on The Cryptography Mailing list at metzdowd.com: "I've been working on a new electronic cash system that's fully peer-to-peer, with no trusted third party. The paper is available at http://www.bitcoin.org/bitcoin.pdf." This link leads to the now-famous white paper published on bitcoin.org entitled "Bitcoin: A Peer-to-Peer Electronic Cash System." This paper would become the Magna Carta for how Bitcoin operates today.
Jan. 3, 2009: The first Bitcoin block is mined, Block 0. This is also known as the "genesis block" and contains the text: "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks," perhaps as proof that the block was mined on or after that date, and perhaps also as relevant political commentary.
Jan. 8, 2009: The first version of the Bitcoin software is announced on The Cryptography Mailing list.
Jan. 9, 2009: Block 1 is mined, and Bitcoin mining commences in earnest.
Who Invented Bitcoin?
No one knows. Not conclusively, at any rate. Satoshi Nakamoto is the name associated with the person or group of people who released the original Bitcoin white paper in 2008 and worked on the original Bitcoin software that was released in 2009. The Bitcoin protocol requires users to enter a birthday upon signup, and we know that an individual named Satoshi Nakamoto registered and put down April 5 as a birth date. And that's about it.
Before Satoshi
Though it is tempting to believe the media's spin that Satoshi Nakamoto is a solitary, quixotic genius who created Bitcoin out of thin air, such innovations do not happen in a vacuum. All major scientific discoveries, no matter how original-seeming, were built on previously existing research. There are precursors to Bitcoin: Adam Back’s Hashcash, invented in 1997, and subsequently Wei Dai’s b-money, Nick Szabo’s bit gold and Hal Finney’s Reusable Proof of Work. The Bitcoin white paper itself cites Hashcash and b-money, as well as various other works spanning several research fields.
Why Is Satoshi Anonymous?
There are two primary motivations for keeping Bitcoin's inventor keeping his or her or their identity secret. One is privacy. As Bitcoin has gained in popularity – becoming something of a worldwide phenomenon – Satoshi Nakamoto would likely garner a lot of attention from the media and from governments.
The other reason is safety. Looking at 2009 alone, 32,489 blocks were mined; at the then-reward rate of 50 BTC per block, the total payout in 2009 was 1,624,500 BTC, which at today’s prices is over $900 million. One may conclude that only Satoshi and perhaps a few other people were mining through 2009 and that they possess a majority of that $900 million worth of BTC. Someone in possession of that much BTC could become a target of criminals, especially since bitcoins are less like stocks and more like cash, where the private keys needed to authorize spending could be printed out and literally kept under a mattress. While it's likely the inventor of Bitcoin would take precautions to make any extortion-induced transfers traceable, remaining anonymous is a good way for Satoshi to limit exposure.
The Suspects
Numerous people have been suggested as possible Satoshi Nakamoto by major media outlets. Oct. 10, 2011, The New Yorker published an article speculating that Nakamoto might be Irish cryptography student Michael Clear or economic sociologist Vili Lehdonvirta. A day later, Fast Company suggested that Nakamoto could be a group of three people – Neal King, Vladimir Oksman and Charles Bry – who together appear on a patent related to secure communications that were filed two months before bitcoin.org was registered. A Vice article published in May 2013 added more suspects to the list, including Gavin Andresen, the Bitcoin project’s lead developer; Jed McCaleb, co-founder of now-defunct Bitcoin exchange Mt. Gox; and famed Japanese mathematician Shinichi Mochizuki.
In December 2013, Techcrunch published an interview with researcher Skye Grey who claimed textual analysis of published writings shows a link between Satoshi and bit-gold creator Nick Szabo. And perhaps most famously, in March 2014, Newsweek ran a cover article claiming that Satoshi is actually an individual named Satoshi Nakamoto – a 64-year-old Japanese-American engineer living in California. The list of suspects is long, and all the individuals deny being Satoshi.
Can Satoshi's Identity Be Proven?
It would seem even early collaborators on the project don’t have verifiable proof of Satoshi’s identity. To reveal conclusively who Satoshi Nakamoto is, a definitive link would need to be made between his/her activity with Bitcoin and his/her identity. That could come in the form of linking the party behind the domain registration of bitcoin.org, email and forum accounts used by Satoshi Nakamoto, or ownership of some portion of the earliest mined bitcoins. Even though the bitcoins Satoshi likely possesses are traceable on the blockchain, it seems he/she has yet to cash them out in a way that reveals his/her identity. If Satoshi were to move his/her bitcoins to an exchange today, this might attract attention, but it seems unlikely that a well-funded and successful exchange would betray a customer's privacy.
Receiving Bitcoins As Payment
Bitcoins can be accepted as a means of payment for products sold or services provided. If you have a brick and mortar store, just display a sign saying “Bitcoin Accepted Here” and many of your customers may well take you up on it; the transactions can be handled with the requisite hardware terminal or wallet address through QR codes and touch screen apps. An online business can easily accept bitcoins by just adding this payment option to the others it offers, like credit cards, PayPal, etc. Online payments will require a Bitcoin merchant tool (an external processor like Coinbase or BitPay).
Working For Bitcoins
Those who are self-employed can get paid for a job in bitcoins. There are several websites/job boards which are dedicated to the digital currency:
Work For Bitcoin brings together work seekers and prospective employers through its websiteCoinality features jobs – freelance, part-time and full-time – that offer payment in bitcoins, as well as Dogecoin and LitecoinJobs4Bitcoins, part of reddit.comBitGigs
Bitcoin From Interest Payments
Another interesting way (literally) to earn bitcoins is by lending them out and being repaid in the currency. Lending can take three forms – direct lending to someone you know; through a website which facilitates peer-to-peer transactions, pairing borrowers and lenders; or depositing bitcoins in a virtual bank that offers a certain interest rate for Bitcoin accounts. Some such sites are Bitbond, BitLendingClub, and BTCjam. Obviously, you should do due diligence on any third-party site.
Bitcoins From Gambling
It’s possible to play at casinos that cater to Bitcoin aficionados, with options like online lotteries, jackpots, spread betting, and other games. Of course, the pros and cons and risks that apply to any sort of gambling and betting endeavors are in force here too.
Investing in Bitcoins
There are many Bitcoin supporters who believe that digital currency is the future. Those who endorse it are of the view that it facilitates a much faster, no-fee payment system for transactions across the globe. Although it is not itself any backed by any government or central bank, bitcoin can be exchanged for traditional currencies; in fact, its exchange rate against the dollar attracts potential investors and traders interested in currency plays. Indeed, one of the primary reasons for the growth of digital currencies like Bitcoin is that they can act as an alternative to national fiat money and traditional commodities like gold.
In March 2014, the IRS stated that all virtual currencies, including bitcoins, would be taxed as property rather than currency. Gains or losses from bitcoins held as capital will be realized as capital gains or losses, while bitcoins held as inventory will incur ordinary gains or losses.
Like any other asset, the principle of buying low and selling high applies to bitcoins. The most popular way of amassing the currency is through buying on a Bitcoin exchange, but there are many other ways to earn and own bitcoins. Here are a few options which Bitcoin enthusiasts can explore.
Risks of Bitcoin Investing
Though Bitcoin was not designed as a normal equity investment (no shares have been issued), some speculative investors were drawn to the digital money after it appreciated rapidly in May 2011 and again in November 2013. Thus, many people purchase bitcoin for its investment value rather than as a medium of exchange.
However, their lack of guaranteed value and digital nature means the purchase and use of bitcoins carries several inherent risks. Many investor alerts have been issued by the Securities and Exchange Commission (SEC), the Financial Industry Regulatory Authority (FINRA), the Consumer Financial Protection Bureau (CFPB), and other agencies.
The concept of a virtual currency is still novel and, compared to traditional investments, Bitcoin doesn't have much of a long-term track record or history of credibility to back it. With their increasing use, bitcoins are becoming less experimental every day, of course; still, after eight years, they (like all digital currencies) remain in a development phase, still evolving. "It is pretty much the highest-risk, highest-return investment that you can possibly make,” says Barry Silbert, CEO of Digital Currency Group, which builds and invests in Bitcoin and blockchain companies.
Bitcoin Regulatory Risk
Investing money into Bitcoin in any of its many guises is not for the risk-averse. Bitcoins are a rival to government currency and may be used for black market transactions, money laundering, illegal activities or tax evasion. As a result, governments may seek to regulate, restrict or ban the use and sale of bitcoins, and some already have. Others are coming up with various rules. For example, in 2015, the New York State Department of Financial Services finalized regulations that would require companies dealing with the buy, sell, transfer or storage of bitcoins to record the identity of customers, have a compliance officer and maintain capital reserves. The transactions worth $10,000 or more will have to be recorded and reported.
Although more agencies will follow suit, issuing rules and guidelines, the lack of uniform regulations about bitcoins (and other virtual currency) raises questions over their longevity, liquidity, and universality.
Security Risk of Bitcoins
Bitcoin exchanges are entirely digital and, as with any virtual system, are at risk from hackers, malware and operational glitches. If a thief gains access to a Bitcoin owner's computer hard drive and steals his private encryption key, he could transfer the stolen Bitcoins to another account. (Users can prevent this only if bitcoins are stored on a computer which is not connected to the internet, or else by choosing to use a paper wallet – printing out the Bitcoin private keys and addresses, and not keeping them on a computer at all.) Hackers can also target Bitcoin exchanges, gaining access to thousands of accounts and digital wallets where bitcoins are stored. One especially notorious hacking incident took place in 2014, when Mt. Gox, a Bitcoin exchange in Japan, was forced to close down after millions of dollars worth of bitcoins were stolen.
This is particularly problematic once you remember that all Bitcoin transactions are permanent and irreversible. It's like dealing with cash: Any transaction carried out with bitcoins can only be reversed if the person who has received them refunds them. There is no third party or a payment processor, as in the case of a debit or credit card – hence, no source of protection or appeal if there is a problem.
Insurance Risk
Some investments are insured through the Securities Investor Protection Corporation. Normal bank accounts are insured through the Federal Deposit Insurance Corporation (FDIC) up to a certain amount depending on the jurisdiction. Bitcoin exchanges and Bitcoin accounts are not insured by any type of federal or government program.
Risk of Bitcoin Fraud
While Bitcoin uses private key encryption to verify owners and register transactions, fraudsters and scammers may attempt to sell false bitcoins. For instance, in July 2013, the SEC brought legal action against an operator of a Bitcoin-related Ponzi scheme.
Market Risk
Like with any investment, Bitcoin values can fluctuate. Indeed, the value of the currency has seen wild swings in price over its short existence. Subject to high volume buying and selling on exchanges, it has a high sensitivity to “news." According to the CFPB, the price of bitcoins fell by 61% in a single day in 2013, while the one-day price drop in 2014 has been as big as 80%.
If fewer people begin to accept Bitcoin as a currency, these digital units may lose value and could become worthless. There is already plenty of competition, and though Bitcoin has a huge lead over the other 100-odd digital currencies that have sprung up, thanks to its brand recognition and venture capital money, a technological break-through in the form of a better virtual coin is always a threat.
Bitcoin's Tax Risk
As bitcoin is ineligible to be included in any tax-advantaged retirement accounts, there are no good, legal options to shield investments from taxation.

My friend invested 200K at 18500$ - take a chill pill, read my points and please contribute/upvote

He is very wealthy, and doesn’t lose sleep at night due to the recent “crash”. It is a 10 year+ bet. He is relaxed and actually buying more now.
Lesson: invest what you can afford to lose. Think long term.
This might be seen as a shit post but it gets on my nerve seeing all the people panicking and complaining in this sub.
BTC has the potential of becoming a competitor to gold, which has a 8T$ market cap. No, it’s not guaranteed - but it has a true chance. Guess what, the world is becoming more and more digital and BTC is until now apart of that revolution and obviously has the potential to continue doing so.
Relax and think long term.
In 2020 another halving is coming and all coins (21M) will be in circulation by 2140 approximately. Well all be dead by 2140.....
Some important factors that theoretically could affect the space: - stock prices are at an ATH. Market is over bought and inflated. If the stock market crashes money surely will go in to crypto. Some people disagree on this, but only time can tell. - a lot of countries around the world are at political and economical unrest. - the US has 21T$ in debt, not sustainable. This will implode at some point. - China has recently started to purchase oil with Yuan instead of dollars. This will affect the dollar in the longer term as dollars will be removed from the market. - the EU is fucked, brexit - and most likely more countries will follow and exit during the next decade.
In the past I’ve seen a lot of post about people saying that BTC is to expensive and that the whales are manipulating the market etc. Yes they are, as they do in all markets. As soon as BTC becomes more liquid it will be way less volatile. But we won’t see that before 1-2T$+
Mining expenses are going one way, up - they have grown exponentially since the very beginning. If someone reinvents the wheel, yes, they might make a huge mining profit short term. But after some months other companies will be creating similar chips and hash rate will sky-rocket: hence, mining profits go down and miners won’t sell before break even or threat of bankruptcy.
After the next halving in 2020 a total of 328125BTC will be added to the market per year, that’s a total of approx 27K per month.
In 2024 a total of 164 062BTC will be added to the market, a total of 13.6K per month.
2028 a total of 6.8K per month.
2032 a total of 3.4K per month.
Do the math, use your logic.
And on my last note, Switzerland is the crypto place to be. The whole government is supportive of bitcoin and Blockchain. Their national bank had a profit of 55$B in 2017. Don’t think their buying BTC behind the scenes? Think again! Would they be stupid enough to announce it, of course not.
Hold and relax, wether it’s real estate, BTC, valuable art, your wife, pension fund. Aim for a good life now and aim for a comfortable life when you get older, be smart!
All the best!
EDIT: - receiving extreme amounts of BS for spelling mistakes. I hate to break it to you, but I’m not a native English speaker. - no, the stock market is not at an ATH, it’s just below. The bull run since 2008 has been incredible. - the last part about the Swiss banks is a guess and somewhat conspiracy theory. You cannot deny the likelihood of banks investing in crypto in the coming years. In my opinion the odds are highest for the banks in countries that are crypto friendly.

If you hodl or trade, you`re the biggest problem with the world of cryptocurrencies.

There`s 3 components to a market economy: Spending, Savings & Investments. We only have 2 and those are way off balance.
Spending: Payments. Drives Inclusion & Adoption. Represents the primary bridge to real world assets.
Saving: Store of Value, Essential driver for stability. The ideea that your holdings are safe over time and don`t depreciate.
Investments: Trading, drives value of the economy, corrects inflation.
State of the nation:
IF there`s any chance at adoption, don`t just HODL. Don`t just DayTrade. Spend what you have. Money needs to move.
The moment you start spending a portion of cryptocurrencies, that money moves. The entire supply chain benefits. Miners Mine, Exchangers Exchange, Businesses get paid, Taxes get taxed. The underlying value of your holdings grows as you tell more people how you paid your AliBaba supplier in Bitcoin and didn`t have any trouble with your EU based bank making a fuss over "why you`re sending money to Asia".
If the only thing you do with Crypto is to buy it, hold it or trade it, it has no impact on real life. It`s not inviting more people to use it. Demand doesn`t grow. the value chain remains closed and non-inclusive. And it`s against the basic principles of Blockchain. You, the person who only has 10 USD in Dogecoin or the Hodler who has 8 bitcoins since Satoshi was in diapers, you`re responsible for the value of your assets and growth of your community. If you don`t SPEND it, people around you have NO reason to adopt. And if they do adopt, they do it for the wrong reasons and simply add to the volatility.
Introduction:
I`ve been in this space since 2009, reading all I could get my hands on. Coming from a poorly banked background and still having frustrations due to the inability of making online purchases at the time, just coming out of a recession, Bitcoin`s vision struck a nerve with me. I`ve been an avid believer in blockchain ever since and at no point did I buy crypto to store value, hedge my bets, invest, digital gold or any of this. I went in because it was, and still is: the easiest way to send money across the world. Ethereum`s smart contracts bring this simple function to a new level, introducing conditions to be met for the transfer itself. Simple, open, transparent, inclusive. Period.
What we`ve become, as a community:
As a whole, this community went from a group of passionate people who wanted an alternative to banks, government and politics, people who wanted to deal directly with other people, to something weird I can`t describe as a whole, but more as personas. Here`s what I`m seeing:
  1. The "I wanna buy Pizza with Bitcoin" crowd. I`m one of them. We just wanted a simple alternative, we were okay with volatility because we always knew the more people use it, more stable it gets as an alternative currency. Conspiracy theorists, tech geeks, scientists, curious people fascinated by the endless possibilities of a global, open banking system, built by the people, for the people. Joined from the first 3-4 years of Bitcoin, many still join it.
  2. The Hodlers: Also coined as the true "Believers". They`re responsible for the initial traction, and would rather liquidate their house than to "sell off" their Bitcoins. They see Bitcoin and other currencies as a "store of value" and see not much difference between buying/storing Gold and Crypto. Joined after the first group and peacefully co-existed with everybody so far. Most dedicated miners came from this group/generation of adopters.
  3. The Traders: People coming from the finance world. They either did Hedgefunds, Forex, VC. Smart opportunists that saw the first 2 groups, saw the potential value of the system as something to be gained from (nothing wrong with this) and heavily capitalize on it. These were the first guys to look at crypto as financial instruments and started fighting the compliance game. This is also where market manipulation started.
  4. The "Tokenize the world" generation. Driven by technology on one side, by the ICO madness on the other side, this opportunistic group wanted to create a token (and respective ICOs) for everything they could think of. Huge similarities between how everything needed a website in the 2000`s, everything needed an app in 2010, everything needed a coin/token started around 2016. Dogecoin is the perfect example of a joke that got way out of proportion, while the original ideea was to make fun of this particular group. Oh well, this group still garners a lot of traction/interest. This group is why we have 3000 shitcoins and who knows how many that never saw the light of day.
  5. The Consultants, Gurus, Ninjas. The "know it all`s". They`re all about the TREND, not about the substance. In the 90`s we had the "internet consultants" who were selling strategies for people to get online. Later the same people were selling strategies to get website traffic. Later, it was about the apps or about the cloud. Right now, it`s about blockchain, token economics, go to market, liquidity, or investing. Some are super smart, most are useless. The only thing that really bothers me is that consultants take no ownership in the success or failure of what they`re selling. As long as you cover their fees, they don`t care if their advice works or not and usually blame you for failing. These are the "market makers" of today, the youtube/facebook/twitteinstagram investment gurus who look at charts for 4 hours and make predictions without really having any skin in the game. Here`s what I never got my head around, if you know how to make a market for a coin, or really know how to invest in crypto.... WHY would you charge me 20k when you can make millions for yourself in less time than that? I guess it holds true: those that can, DO, those that can`t, Teach.
This brings us to the state of the market today.
Proposed solution:
Don`t wait for your government to regulate, don`t wait for banks or institutional investors to kick in, don`t wait for the media frenzy. Just do your part: spend, save and invest your crypto just as you would your USD/Euro/Yen/etc. If you`re a freelancer, accept crypto payments. if you run a business, accept crypto payments. If you have crypto, make crypto payments. This is the main reason we have crypto today and it`s exactly what we don`t use it for. Go back to basics and let`s see how influenced by "market volatility" or "market manipulation" or "media bias" the price will get.
Disclosure: Yes, trying to solve the adoption issue has led me to build a platform for e-commerce that also solves crypto-to-fiat payments for more than 2000 tokens. We walk the walk, not talk the talk.
I`d love to hear if you guys agree or disagree, and most importantly, Why?
C:\>
P.S. I love you

If you just hodl or trade, you`re the biggest problem with the world of cryptocurrencies.

TL;DR: There`s 3 components to a market economy: Spending, Savings & Investments. We only have 2 and those are way off balance.
Spending: Payments. Drives Inclusion & Adoption. Represents the primary bridge to real world assets.
Saving: Store of Value, Essential driver for stability. The ideea that your holdings are safe over time and don`t depreciate.
Investments: Trading, drives value of the economy, corrects inflation.
State of the nation:
IF there`s any chance at adoption, don`t just HODL. Don`t just DayTrade. Spend what you have. Money needs to move.
The moment you start spending a portion of cryptocurrencies, that money moves. The entire supply chain benefits. Miners Mine, Exchangers Exchange, Businesses get paid, Taxes get taxed. The underlying value of your holdings grows as you tell more people how you paid your AliBaba supplier in Bitcoin and didn`t have any trouble with your EU based bank making a fuss over "why you`re sending money to Asia".
If the only thing you do with Crypto is to buy it, hold it or trade it, it has no impact on real life. It`s not inviting more people to use it. Demand doesn`t grow. the value chain remains closed and non-inclusive. And it`s against the basic principles of Blockchain. You, the person who only has 10 USD in Dogecoin or the Hodler who has 8 bitcoins since Satoshi was in diapers, you`re responsible for the value of your assets and growth of your community. If you don`t SPEND it, people around you have NO reason to adopt. And if they do adopt, they do it for the wrong reasons and simply add to the volatility.
Introduction:
I`ve been in this space since 2009, reading all I could get my hands on. Coming from a poorly banked background and still having frustrations due to the inability of making online purchases at the time, just coming out of a recession, Bitcoin`s vision struck a nerve with me. I`ve been an avid believer in blockchain ever since and at no point did I buy crypto to store value, hedge my bets, invest, digital gold or any of this. I went in because it was, and still is: the easiest way to send money across the world. Ethereum`s smart contracts bring this simple function to a new level, introducing conditions to be met for the transfer itself. Simple, open, transparent, inclusive. Period.
What we`ve become, as a community:
As a whole, this community went from a group of passionate people who wanted an alternative to banks, government and politics, people who wanted to deal directly with other people, to something weird I can`t describe as a whole, but more as personas. Here`s what I`m seeing:
  1. The "I wanna buy Pizza with Bitcoin" crowd. I`m one of them. We just wanted a simple alternative, we were okay with volatility because we always knew the more people use it, more stable it gets as an alternative currency. Conspiracy theorists, tech geeks, scientists, curious people fascinated by the endless possibilities of a global, open banking system, built by the people, for the people. Joined from the first 3-4 years of Bitcoin, many still join it.
  2. The Hodlers: Also coined as the true "Believers". They`re responsible for the initial traction, and would rather liquidate their house than to "sell off" their Bitcoins. They see Bitcoin and other currencies as a "store of value" and see not much difference between buying/storing Gold and Crypto. Joined after the first group and peacefully co-existed with everybody so far. Most dedicated miners came from this group/generation of adopters.
  3. The Traders: People coming from the finance world. They either did Hedgefunds, Forex, VC. Smart opportunists that saw the first 2 groups, saw the potential value of the system as something to be gained from (nothing wrong with this) and heavily capitalize on it. These were the first guys to look at crypto as financial instruments and started fighting the compliance game. This is also where market manipulation started.
  4. The "Tokenize the world" generation. Driven by technology on one side, by the ICO madness on the other side, this opportunistic group wanted to create a token (and respective ICOs) for everything they could think of. Huge similarities between how everything needed a website in the 2000`s, everything needed an app in 2010, everything needed a coin/token started around 2016. Dogecoin is the perfect example of a joke that got way out of proportion, while the original ideea was to make fun of this particular group. Oh well, this group still garners a lot of traction/interest. This group is why we have 3000 secondary coins and who knows how many that never saw the light of day.
  5. The Consultants, Gurus, Ninjas. The "know it all`s". They`re all about the TREND, not about the substance. In the 90`s we had the "internet consultants" who were selling strategies for people to get online. Later the same people were selling strategies to get website traffic. Later, it was about the apps or about the cloud. Right now, it`s about blockchain, token economics, go to market, liquidity, or investing. Some are super smart, most are useless. The only thing that really bothers me is that consultants take no ownership in the success or failure of what they`re selling. As long as you cover their fees, they don`t care if their advice works or not and usually blame you for failing. These are the "market makers" of today, the youtube/facebook/twitteinstagram investment gurus who look at charts for 4 hours and make predictions without really having any skin in the game. Here`s what I never got my head around, if you know how to make a market for a coin, or really know how to invest in crypto.... WHY would you charge me 20k when you can make millions for yourself in less time than that? I guess it holds true: those that can, DO, those that can`t, Teach.
This brings us to the state of the market today.
Proposed solution:
Don`t wait for your government to regulate, don`t wait for banks or institutional investors to kick in, don`t wait for the media frenzy. Just do your part: spend, save and invest your crypto just as you would your USD/Euro/Yen/etc. If you`re a freelancer, accept crypto payments. if you run a business, accept crypto payments. If you have crypto, make crypto payments. This is the main reason we have crypto today and it`s exactly what we don`t use it for. Go back to basics and let`s see how influenced by "market volatility" or "market manipulation" or "media bias" the price will get.
Disclosure: Yes, trying to solve the adoption issue has led me to build a platform for e-commerce that also solves crypto-to-fiat payments for more than 2000 tokens. We walk the walk, not talk the talk.
I`d love to hear if you guys agree or disagree, and most importantly, Why?
C:\>
P.S. I love you

A lengthy explanation on why BS really limited the blocksize

I found this explanation in the comments about BS's argument against raising the blocksize which doesn't get much focus here:
In my understanding, allowing Luke to run his node is not the reason, but only an excuse that Blockstream has been using to deny any actual block size limit increase. The actual reason, I guess, is that Greg wants to see his "fee market" working. It all started on Feb/2013. Greg posted to bitcointalk his conclusion that Satoshi's design with unlimited blocks was fatally flawed, because, when the block reward dwindled, miners would undercut each other's transaction fees until they all went bakrupt. But he had a solution: a "layer 2" network that would carry the actual bitcoin payments, with Satoshi's network being only used for large sporadic settlements between elements of that "layer 2".
(At the time, Greg assumed that the layer 2 would consist of another invention of his, "pegged sidechains" -- altcoins that would be backed by bitcoin, with some cryptomagic mechanism to lock the bitcoins in the main blockchain while they were in use by the sidechain. A couple of years later, people concluded that sidechains would not work as a layer 2. Fortunately for him, Poon and Dryja came up with the Lightning Network idea, that could serve as layer 2 instead.)
The layer 1 settlement transactions, being relatively rare and high-valued, supposedly could pay the high fees needed to sustain the miners. Those fees would be imposed by keeping the block sizes limited, so that the layer-1 users woudl have to compete for space by raising their fees. Greg assumed that a "fee market" would develop where users could choose to pay higher fees in exchange of faster confirmation.
Gavin and Mike, who were at the time in control of the Core implementation, dismissed Greg's claims and plans. In fact there were many things wrong with them, technical and economical. Unfortunately, in 2014 Blockstream was created, with 30 M (later 70 M) of venture capital -- which gave Greg the means to hire the key Core developers, push Gavin and Mike out of the way, and make his 2-layer design the official roadmap for the Core project.
Greg never provided any concrete justification, by analysis or simulation, for his claims of eventual hashpower collapse in Satoshi's design or the feasibility of his 2-layer design.
On the other hand, Mike showed, with both means, that Greg's "fee market" would not work. And, indeed, instead of the stable backlog with well-defined fee x delay schedule, that Greg assumed, there is a sequence of huge backlogs separated by periods with no backlog.
During the backlogs, the fees and delays are completely unpredictable, and a large fraction of the transactions are inevitably delayed by days or weeks. During the intemezzos, there is no "fee market' because any transaction that pays the minimum fee (a few cents) gets confirmed in the next block.
That is what Mike predicted, by theory and simulations -- and has been going on since Jan/2016, when the incoming non-spam traffic first hit the 1 MB limit. However, Greg stubbornly insists that it is just a temporary situation, and, as soon as good fee estimators are developed and widely used, the "fee market" will stabilize. He simply ignores all arguments of why fee estimation is a provably unsolvable problem and a stable backlog just cannot exist. He desperately needs his stable "fee market" to appear -- because, if it doesn't, then his entire two-layer redesign collapses.
That, as best as I can understand, is the real reason why Greg -- and hence Blockstream and Core -- cannot absolutely allow the block size limit to be raised. And also why he cannot just raise the minimum fee, which would be a very simple way to reduce frivolous use without the delays and unpredictability of the "fee market". Before the incoming traffic hit the 1 MB limit, it was growing 50-100% per year. Greg already had to accept, grudgingly, the 70% increase that would be a side effect of SegWit. Raising the limit, even to a miser 2 MB, would have delayed his "stable fee market" by another year or two. And, of course, if he allowed a 2 MB increase, others would soon follow.
Hence his insistence that bigger blocks would force the closure of non-mining relays like Luke's, which (he incorrectly claims) are responsible for the security of the network, And he had to convince everybody that hard forks -- needed to increase the limit -- are more dangerous than plutonium contaminated with ebola.
SegWit is another messy imbroglio that resulted from that pile of lies. The "malleability bug" is a flaw of the protocol that lets a third party make cosmetic changes to a transaction ("malleate" it), as it is on its way to the miners, without changing its actual effect.
The malleability bug (MLB) does not bother anyone at present, actually. Its only serious consequence is that it may break chains of unconfirmed transactions, Say, Alice issues T1 to pay Bob and then immediately issues T2 that spends the return change of T1 to pay Carol. If a hacker (or Bob, or Alice) then malleates T1 to T1m, and gets T1m confirmed instead of T1, then T2 will fail.
However, Alice should not be doing those chained unconfirmed transactions anyway, because T1 could fail to be confirmed for several other reasons -- especially if there is a backlog.
On the other hand, the LN depends on chains of the so-called bidirectional payment channels, and these essentially depend on chained unconfirmed transactions. Thus, given the (false but politically necessary) claim that the LN is ready to be deployed, fixing the MB became a urgent goal for Blockstream.
There is a simple and straightforward fix for the MLB, that would require only a few changes to Core and other blockchain software. That fix would require a simple hard fork, that (like raising the limit) would be a non-event if programmed well in advance of its activation.
But Greg could not allow hard forks, for the above reason. If he allowed a hard fork to fix the MLB, he would lose his best excuse for not raising the limit. Fortunately for him, Pieter Wuille and Luke found a convoluted hack -- SegWit -- that would fix the MLB without any hated hard fork.
Hence Blockstream's desperation to get SegWit deployed and activated. If SegWit passes, the big-blockers will lose a strong argument to do hard forks. If it fails to pass, it would be impossible to stop a hard fork with a real limit increase.
On the other hand, SegWit needed to offer a discount in the fee charged for the signatures ("witnesses"). The purpose of that discount seems to be to convince clients to adopt SegWit (since, being a soft fork, clients are not strictly required to use it). Or maybe the discount was motivated by another of Greg's inventions, Confidential Transactions (CT) -- a mixing service that is supposed to be safer and more opaque than the usual mixers. It seems that CT uses larger signatures, so it would especially benefit from the SegWit discount.
Anyway, because of that discount and of the heuristic that the Core miner uses to fill blocks, it was also necessary to increase the effective block size, by counting signatures as 1/4 of their actual size when checking the 1 MB limit. Given today's typical usage, that change means that about 1.7 MB of transactions will fit in a "1 MB" block. If it wasn't for the above political/technical reasons, I bet that Greg woudl have firmly opposed that 70% increase as well.
If SegWit is an engineering aberration, SegWit2X is much worse. Since it includes an increase in the limit from 1 MB to 2 MB, it will be a hard fork. But if it is going to be a hard fork, there is no justification to use SegWit to fix the MLB: that bug could be fixed by the much simpler method mentioned above.
And, anyway, there is no urgency to fix the MLB -- since the LN has not reached the vaporware stage yet, and has yet to be shown to work at all.
I'd like to thank u/iwannabeacypherpunk for pointing this out to me.

The risk of betting against bitcoin  Short View Chinese Bitcoin Miners Moving to America and Canada? Miner Exodus Begins! Why are these people betting against Bitcoin?!? What are the qualities of online gambling 2270 santosi new tricks show now

Bitcoin bulls have repeatedly claimed that the cryptocurrency price will hit $20,000 shortly. While many analysts believe it would happen, some disagree. Yashu Gola 16 mins ago; Bitcoin Creates Strong Tailwind as Traders Rotate Capital... Bitcoin’s price has begun consolidating following its immense surge seen throughout the past 48 hours Yesterday afternoon, it rallied as high as $13,200 A FUD regarding Bitcoin miner ‘death spiral’ had been surfacing the crypto community as the halving was underway. However, the latest charts suggest otherwise as hash rate hits an all-time high. Miner’s Miles Away From ‘Death Spiral’ The first and the largest cryptocurrency, Bitcoin was programmed to undergo a process called the “halving” once, every Bitcoin has almost half the inflation rate of world average after halving; Bitcoin miner Ebang attempts second IPO for USD 100 million in USA . Bitcoin markets managed to do exactly as the bulls would have hoped for over the weekend, staying well above USD 7,000 and managing to keep above USD 7,500 the entire day on Sunday. From a world where political leanings used to be personal, massive public attention and media campaigns now reign supreme. One of the most interesting developments to come out of this change is the rise of political betting. As a way to show faith in certain parties or leaders, this form of betting has drawn in new crowds and given existing speculators yet another avenue in which to engage. Reports from China indicate that senior executives of Canaan creatives, one of leading bitcoin miner manufacturer, have been fired. The purge at Hangzhou offices was instigated by Zhang Nan Geng—the founder. Xiangfu Liu, the co-founder, has also reportedly left the board.
