Below the fold is the text, with links to the sources.
Before the recent "crypto winter", the words you heard about cryptocurrencies were "innovative", "potential" and "decentralized". This story is about my part in showing that they are all false. I should stress that I hold no long or short positions in cryptocurrencies, their derivatives or related companies. Unlike most people discussing them, I am not "talking my book". As usual the text of my talk with links to the sources will go up on my blog after the session. I plan to leave about 10 minutes for discussion, so please hold questions.
Then a quarter-century ago Vicky and I were hiking in Joseph Grant State Park when she explained to me how uncomfortable librarians were at being forced to switch from owning a copy of the journals to which they subscribed, to renting access to the publisher's copy.
I came up with an idea as to how they could own a copy; libraries would run a transparent Web cache, a digital version of the stacks. They would pre-load it with their subscription journals using a Web crawler, and simply never flush the cache. A couple of months later hiking Big Basin I came up with my one great acronym; LOCKSS for Lots Of Copies Keep Stuff Safe.
- Even back then libraries were under severe budget pressure, so the hardware and staff costs had to be very low.
- Despite that, the system had to be extremely reliable to compete with the longevity of paper.
- The journals were owned by the most rapacious copyright holders on the planet. If there were a central organization running the caches, it would get instantly sued out of existence.
- Despite that, the system had to resist attacks aimed at altering or leaking content. Even long before the foes of "cancel culture" focused on banning books from libraries, organized groups were using razor blades to remove articles on, for example, abortion from journals in the stacks.
Although the prototype Web cache, Web crawler, hash voting and repair systems all worked well, my first two attempts at an inter-cache protocol that resisted Sybil attacks didn't. It wasn't until I worked with Petros Maniatis, TJ Giuli and Mema Roussopolous, brilliant students of Prof. Mary Baker at Stanford CS, that we figured out how to do it.
A couple of years later the system was in production at libraries worldwide, and we were learning a lot about the operation of peer-to-peer networks at (modest) scale.
In effect Nakamoto used a Proof-of-Work poll tax to make voting on the content of the next block in the chain expensive. The work needed was to guess a nonce that resulted in the hash of the block having a set number of leading zeros. This was expensive in computation, so he repaid the cost by inflating the currency with a block reward for the winner of the guessing competition, some newly created Bitcoin.
I am oversimplifying. The Proof-of-Work mechanism selects a node to verify a block, and the nodes achieve consensus on the block via the Longest Chain Rule, the only component of the Bitcoin protocol that was really new with Nakamoto. But in the big picture this performs the same function as voting in a permissioned system using Byzantine Fault Tolerance, and the analogy helps my exposition.A little while later I found out about it and, as someone who had launched a permissionless, decentralized peer-to-peer network using Proof-of-Work some years earlier, doubted that it would succeed despite its evident cleverness. Based on our experience with LOCKSS, my reasons included:
- We had discovered that, to be an effective Sybil defense, the cost imposed by Proof-of-Work had to be vastly higher than the cost of the functions it was defending. A digital currency that was very expensive to run didn't seem like a great idea. A decade later Eric Budish would put this insight on a firm theoretical foundation in The Economic Limits Of Bitcoin And The Blockchain, showing that to be safe the value of the transactions in a block should not exceed the value of the block reward2.
- The goal of Proof-of-Work in both Bitcoin and LOCKSS was to avoid the need for peers to trust each other. But this didn't mean that the system was perceived as, or was actually, free of trust. In practice peers had to at least trust the core developers of the protocol. Recent DARPA-sponsored research shows many other parties needing to be trusted3.
Pretty soon after Bitcoin's launch it became clear that the need to wait an hour for finality, and the large proportion of transactions that simply failed, meant you couldn't really pay for anything legal with it. In 2021 Amir Kafshdar Goharshady published Irrationality, Extortion, or Trusted Third-parties: Why it is Impossible to Buy and Sell Physical Goods Securely on the Blockchain.
In particular, you couldn't pay the hardware, power, cooling and staff time needed to pay the poll tax in Bitcoin. You had to pay in what the Bitcoin cognoscenti sneeringly called "fiat", actual dollars. To convert the block rewards into actual dollars you needed exchanges that would set a "price" for a Bitcoin in dollars. The exchange would let you sell your Bitcoin and credit you with "dollars" in your account. But you can't run a cryptocurrency exchange by FedEx-ing stacks of $100 bills to and fro so, crucially, the exchange needs banking services to transfer dollars from your exchange account to your bank account so you can actually pay your bills and buy the Lamborghini. Thus, in practice, Nakamoto's goal of avoiding trust in banks was a failure4.
Thus only 21 months after Bitcoin launched, Mt. Gox became the first significant Bitcoin exchange. As with exchanges in the real world, the quoted "price" represented what a greater fool would pay, because they believed that an even greater fool would pay an even greater "price" in the future. In Bitcoin's case, the greater fools didn't even have the reassurance of "analysts' estimates" of future earnings, because you didn't need an analyst to know that the future earnings were zero.
So as well as continuing to trust banks, cryptocurrency users ended up trusting exchanges that were much less trustworthy. Mt. Gox, for example, was coded in PHP and run initially by one guy, who then sold it to a convicted fraudster.
Once people tried centralized exchanges, they realized the user experience was far better than transacting directly on the blockchain, so exchanges rapidly became popular. In June 2011 Mt. Gox pioneered one of the major features of the cryptocurrency exchange user experience, getting robbed. About 25,000 BTC vanished from nearly 500 accounts.
Nakamoto's scheme motivated early adoption by rapidly inflating the currency with large block rewards, then exponentially decreasing them, so he could claim the currency was non-inflationary (eventually). The result was that early adopters accumulated large numbers of Bitcoin, and the Gini coefficients of cryptocurrencies became extreme.
And, boy, do they ever. In Making Sure "Number Go Up" I survey research showing the prevalence of wash trading, pump-and-dump schemes, and the un-backed printing of stablecoins. The SEC has steadfastly refused to approve a Bitcoin ETF because the market is completely manipulated. So every time you hear me say "price" you need to imagine it has quotes around it.

It wasn't until 2013 that a paper by Ittay Eyal and Emin Gun Sirer caught my attention. Entitled Majority is not Enough: Bitcoin Mining is Vulnerable, it described the "selfish mining" attack on Bitcoin, which I related to one of the attacks against LOCKSS. That started me thinking about Bitcoin and what we had learned about peer-to-peer systems.
By February 2014, despite the earlier thefts and many other legal problems, and with Bitcoin already down about 40% on the year, Mt. Gox was handling 70% of all Bitcoin trades. It was so much easier and more effective than the Bitcoin blockchain, and like fiat exchanges benefited greatly from network effects. At which point it declared bankruptcy, having lost at least 750,000 Bitcoin then "worth" about $377M.
That fall, as Vicky and I were on vacation in Mendocino, I figured out something fundamental about cryptocurrencies, and wrote Economies of Scale in Peer-to-Peer Networks. This was that, because voting in these systems had to be expensive, voters needed to earn a profit by voting. Because technologies have strong economies of scale, the bigger the voter, the higher the profit margin. So these systems would end up centralized.
I wasn't being prophetic. Four months earlier the Ghash.io mining pool had controlled over 51% of Bitcoin mining power for an extended period. My insight wasn't that this would happen, but rather that it was made inevitable by the economics of technology. In 2018 Arnosti and Weinberg, and in 2019 Yulin Kwon et al put my insight on firm theoretical foundations.
What are "mining pools"? They are a symptom of another force driving centralization. Nakamoto's vision was of a large number of roughly equal nodes voting — "one CPU one vote". Suppose there were 100 of them. The system is designed to generate a new block every 10 minutes. Thus on average a node will receive a block reward about once every 17 hours.
The idea of one node per ASIC makes no sense. To get a reward once a day now requires about 175,000 ASICs, 99.7% of which will be trashed without ever earning anything. Now you see why cryptocurrency mining companies are going bankrupt one after another, and where Bitcoin's massive e-waste problem comes from.
|2 pools control BTC|
In January 2015 Bitcoin completed its first 75% drop in "price" over a year.
The Bitcoin blockchain was constrained in its ability to separate suckers from their money because it only implemented transactions. Thus Ethereum, a Turing-complete blockchain whose "smart contracts" allowed far more creative techniques became popular. Over time it became evident that deploying immutable software had risks, so "smart contracts" that were "decentralized in name only" also became "immutable in name only" or "upgradeable".
In June 2016 "The DAO", the first major smart contract, after accumulating 14% of all the ETH in circulation and ignoring repeated warnings, suffered a reentrancy bug which allowed the theft of about $50M. The theft was reversed by a hard fork, demonstrating the limits of purported decentralization.
In August 2016 the BitFinex exchange, which had taken over from Mt. Gox as the largest Bitcoin exchange, was robbed of almost 130K Bitcoin, then "worth" about $72M, second only to the Mt. Gox theft. Two months earlier Bitfinex had settled with the CFTC for $75K for multiple violations. In February 2022, the DoJ seized most of the loot, then "worth" about $3.6B, and charged Ilya Lichtenstein and Heather Morgan with the theft.
In December 2018 Bitcoin completed its second 75% drop in "price" in a year.
whatever consensus mechanism they use, permissionless blockchains are not sustainable for very fundamental economic reasons. These include the need for speculative inflows and mining pools, security linear in cost, economies of scale, and fixed supply vs. variable demand. Proof-of-work blockchains are also environmentally unsustainable.
Already in 2014 the digital preservation world had been infected with the blockchain hype, which led to a stream of skeptical posts on my blog and eventually an invitation from Cliff Lynch to present at CNI. I put quite a lot of work into Blockchain: What's Not To Like?, and I reprised it at the April 2019 Asilomar Microcomputer Workshop, and in July 2019 for the Dept. of Defense. The basic idea was that permissionless blockchains weren't a good idea because economies of scale meant they weren't decentralized, and they weren't sustainable being dependent upon speculation and a vast carbon footprint.
And, of course, basing long-term preservation on something that can often lose 75% of its value in a year is a bit of a risk.
In January 2019 Quadriga CX, the biggest exchange in Canada filed for bankruptcy missing C$188M amid suspicions that its CEO faked his death7.
In April the New York Attorney General sued Bitfinex over an $850M hole in their reserves8.
In May Binance lost 7000 BTC to a heist and suspended withdrawals for a week.
By this time it was already possible for Wall St. firms to make serious money making leveraged bets on cryptocurrencies' extreme volatility. Decentralized Finance (DeFi) sprang up for less well-resourced holders who simply wanted interest on their coins. It was described as peer-to-peer lending via "smart contracts". This sounds like the lender and the borrower were equals, but in practice the lenders' coins were borrowed by the big trading firms to fuel their trades, another example of the deceptive nature of "decentralized".
In April 2020 the dForce DeFi protocol lost $25M to a reentrancy bug similar to The DAO's in June 2016.
It is now October 2021 and John Markoff invites me to talk virtually about cryptocurrencies to the TTI/Vanguard Institutional Investor conference. Without thinking I said yes. Then I checked their website for the programs of previous conferences, and got totally intimidated by the caliber of their speakers. I spent the next two months frantically drafting and re-drafting the talk that was eventually entitled Can We Mitigate Cryptocurrencies' Externalities?.
That month the CFTC settled with Tether and Bitfinex for $42.5M for false claims about Tether's backing, and violating their 2016 settlement.
|BTC 11 Nov 21|
Despite being a big contrast to the other cryptocurrency talk, Can We Mitigate Cryptocurrencies' Externalities? was well received. The whole conference was very impressive, and I got to tell Kim Stanley Robinson how wrong he was about cryptocurrency in The Ministry for the Future!
Things had returned to normal when, on the afternoon of February 8th, Dennis Allison e-mailed me saying the speaker for the next day's EE380 seminar had canceled, and could I step in? I agreed to, and hastily expanded and updated the TTI/Vanguard talk. Thanks to Dave Farber, Cory Doctorow and other reviews, the blog post with the text has garnered 482K, and the YouTube video 12K views.
The talk starts by listing the externalities that cryptocurrencies impose on the rest of us:
Bitcoin is notorious for consuming as much electricity as the Netherlands, but there are around 10,000 other cryptocurrencies, most using similar infrastructure and thus also in aggregate consuming unsustainable amounts of electricity. Bitcoin alone generates as much e-waste as the Netherlands, cryptocurrencies suffer an epidemic of pump-and-dump schemes and wash trading, they enable a $5.2B/year ransomware industry, they have disrupted supply chains for GPUs, hard disks, SSDs and other chips, they have made it impossible for web services to offer free tiers, and they are responsible for a massive crime wave including fraud, theft, tax evasion, funding of rogue states such as North Korea, drug smuggling, and even as documented by Jameson Lopp's list of physical attacks, armed robbery, kidnapping, torture and murder.
Much to my surprise, I was one of a group of "experts" invited to a May meeting of the White House Round Table on Digital Assets, part of the policy development process sparked by the President's Executive Order on Ensuring Responsible Development of Digital Assets. In summary, my message was:
- Permissioned blockchains are overtly centralized, and permissionless blockchains are actually centralized.
- The entire purpose of permissionless blockchains is to evade regulation by diffusing responsibility. In Prof. Angela Walch's words:
the common meaning of ‘decentralized’ as applied to blockchain systems functions as a veil that covers over and prevents many from seeing the actions of key actors within the system.
- Regulators should pay no attention to the claim of "decentralization" and focus on the actual loci of centralization in both permissioned and permissionless systems. Regulators cannot let smearing operations out over many allegedly but not actually independent nodes render regulation futile.
- The goal of regulation should be to isolate cryptocurrencies from fiat by clamping down on exchanges such as Binance and Coinbase, and (meta)stablecoins such as Tether.
Why choose these three as priority targets?
Binance is the dominant cryptocurrrency exchange in both the spot market, where it handles two of every three trades, and the much larger derivatives market. It has been laser-focused on avoiding regulation, claiming not to be headquartered anywhere. Investigations by Angus Berwick and Tom Wilson at Reuters and others have revealed among other things money laundering, sanctions evasion, that supposedly independent Binance.us is a false-front, unbacked (meta)stablecoins, retrospective re-writing of their blockchain, and a 5-year-long DoJ investigation.
Coinbase is much smaller that Binance but its importance is that it is the largest exchange that is a US public company and holds an SEC broker-dealer license. But I documented in The Exchange You Can Trust and Dominoes its many problems9.
Tether (USDT) dominates the (meta)stablecoin marked with an alleged "market cap" about $79B. It has never been audited, and has been described as being "practically quilted out of red flags". The nearest competitor is Circle, whose USDC has a "market cap" around $33B, but has been credibly audited.
At the start of May Bitcoin had been about $40K, down a mere 41% in six months but on the 9th the downfall accelerated as the Terra/Luna algorithmic metastablecoin system crashed and Bitcoin dropped another 25%.
this excess depreciation means that the company's real cost for creating income is much higher than they report, and thus their real profit as a continuing business is much less than they report, because they are not putting aside the money they will need to replace obsolete hardware.
In June the bankruptcies started. As the Bitcoin "price" dropped from $31K on June 7 to $18K on June 16 the Bicoin hash rate dropped 39% from 266EH/s to 163EH/s, showing that the miners were in real trouble. Estimates at the time were that most miners' break-even point was around $30K. Among the struggling miners was Marathon:
the company that in its 2021 fiscal year paid its management $164M on sales of $150.5M. It is now losing $10K on every Bitcoin it mines.Their 2022 results show a net loss of $150M.
As the downfall continued, several things became obvious. First, that the entire ecosystem of exchanges and traders was based on fraud. Silicon Valley Bank failed because many of its assets, long-dated bonds, had lost a proportion of their value when they needed to sell them. But the bulk of the assets of exchanges such as Celsius, FTX and Binance were ther own private tokens, CEL, FTT and BNB. And when they needed to sell them the tokens were worth nothing.
Here's how private tokens work. An exchange mints a billion of them, then sells 100 of them to a straw buyer for $1,000. Now the exchange is "worth" $10B. And if, as Celsius and FTX did, they use the customer dollars coming in to buy up any tokens the public want to sell, they can keep the illusion going. Remember, cryptocurrency markets are completely manipulated. But when someone, Ian Allison in the case of FTX, points out the illusion, there are no buyers.
Second, that the level of financial incompetence in the cryptocurrency ecosystem was staggering. To take just one example, four days after Three Arrows Capital collapsed, it turned out that 3/4 of Voyager Digital's assets were uncollateralized loans to the failed company.
Third, that the cryptocurrency ecosystem was very vulnerable to contagion because it was tightly connected. Voyager and 3AC were an example, as were Genesis and the Winklevoss twins' Gemini - the twins had to rescue it with a $100M personal loan10.
Fourth, that the level of technical incompetence was staggering. For example, FTX's liquidators found "private keys to over $100 million in Ethereum assets stored in plain text and without encryption on an FTX Group server" and "FTX generally didn't use multisigs. When they did, they stored all of the keys together in one place, thus defeating the purpose.".
The benefit of the downfall was that it freed regulators from massive lobbying efforts by the crypto-sphere ($80M from SBF alone). What have they been doing with their new-found freedom?
- The SEC and the New York Attorney General have been using settlements and lawsuits to establish that pretty much all cryptocurrrencies and tokens, except Bitcoin, are securities and thus regulated by the SEC, not the hitherto crypto-friendly CFTC. This now especially includes Ethereum, because staking clearly satisfies the Howey Test.
- The Federal Reserve and other banking regulators issued a joint statement putting US banks on notice that dealing with cryptocurrency companies risks their banking license. Note that the two main crypto-friendly banks both collapsed in a single weekend.
- The regulators are increasing their efforts to ensure that banks and their cryptocurrency customers have proper KYC/AML processes in place.
- The SEC has continued to refuse all requests for a spot Bitcoin ETF. They have many objections, but the most important is that the Bitcoin market is heavily manipulated11.
This is obvious in the recent rise in Bitcoin's "price" back to levels where miners can profit. Liquidity has dried up, making manipulation much easier, and people are buying Bitcoin on exchanges such as Binance that lose banking and transferring them to Coinbase to cash out12.
And the regulators are focused on at least some of the priority targets:
- The CFTC sued Binance and its CEO Changpeng Zhao for violating rules on derivatives trading. Binance handles around 3 of every 4 derivative trades. The complaint shows that the DoJ's 5-year-long investigation has detailed access to Binance's internal communications, and that major Wall St. firms have been evading the law to trade on Binance.
- The SEC sent Coinbase a Wells notice, signalling an impending lawsuit. This likely relates to their staking service; in February the SEC settled with the smaller Kraken exchange on the basis that their staking service was an unregistered security.
- The SEC sued Justin Sun of TRON and the Huboi exchange for wash trading unregistered securities, and eight "influencers" for touting them.
- But so far no action on Tether.

Thanks are due to many people, from my point of view especially to those on this slide.
- This post's title was inspired by Spike Milligan's Adolf Hitler: My Part in His Downfall, the first volume of his memoir of WWII. I apologize for the implicit Godwin's law violation; I think cryptocurrencies are bad, but not that bad.
- The Bitcoin network currently transacts about 100K BTC/day, or an average of nearly 700 BTC/block, so the network exceeds Budish's safety criterion by more than two orders of magnitude. See Sybil Defense.
The report from Trail of Bits is entitled Are Blockchains Decentralized?. Among their findings are:
- Every widely used blockchain has a privileged set of entities that can modify the semantics of the blockchain to potentially change past transactions.
- The number of entities sufficient to disrupt a blockchain is relatively low: four for Bitcoin, two for Ethereum, and less than a dozen for most PoS networks.
- The vast majority of Bitcoin nodes appear to not participate in mining and node operators face no explicit penalty for dishonesty.
Bitcoin has failed to achieve any of Nakamoto's goals:
What is needed is an electronic payment system based on cryptographic proof instead of trust, allowing any two willing parties to transact directly with each other without the need for a trusted third party. Transactions that are computationally impractical to reverse would protect sellers from fraud, and routine escrow mechanisms could easily be implemented to protect buyers.In practice, Bitcoin is not a usable "payment system" because:
- Its value is extremely volatile.
- The supply of transactions is fixed and very small, but the demand for transactions is variable, leading to massive fee spikes at busy times.
- Fees are too high for everyday transactions to be economic.
- Transactions take too long, requiring an hour for finality.
- Transacting on the Bitcoin blockchain requires impractical levels of operational security.
In practice Bitcoin users need to trust the core developers, the operators of the major mining pools, the exchanges, and the banks those exchanges use. This is a lot more trust than simply using banks directly. In practice, irreversible transactions are a major cause of crime. And, in practice, "routine escrow mechanisms" require trusting third parties (see Amir Kafshdar Goharshady's Irrationality, Extortion, or Trusted Third-parties: Why it is Impossible to Buy and Sell Physical Goods Securely on the Blockchain).
The incentive can also be funded with transaction fees. If the output value of a transaction is less than its input value, the difference is a transaction fee that is added to the incentive value of the block containing the transaction. Once a predetermined number of coins have entered circulation, the incentive can transition entirely to transaction fees and be completely inflation free.Alas, Raphael Auer shows that a fee-only system is insecure. Even Nakamoto understood this:
The incentive may help encourage nodes to stay honest. If a greedy attacker is able to assemble more CPU power than all the honest nodes, he would have to choose between using it to defraud people by stealing back his payments, or using it to generate new coins. He ought to find it more profitable to play by the rules, such rules that favour him with more new coins than everyone else combined, than to undermine the system and the validity of his own wealth.Nakamoto was very concerned with privacy:
The necessity to announce all transactions publicly precludes this method, but privacy can still be maintained by breaking the flow of information in another place: by keeping public keys anonymous. The public can see that someone is sending an amount to someone else, but without information linking the transaction to anyone.In practice, the advice to use a new key-pair for each transaction is impractical, a business opportunity for companies such as Chainalysis.
As an additional firewall, a new key pair should be used for each transaction to keep them from being linked to a common owner. Some linking is still unavoidable with multi-input transactions, which necessarily reveal that their inputs were owned by the same owner. The risk is that if the owner of a key is revealed, linking could reveal other transactions that belonged to the same owner.
There are two kinds of "stablecoins", both of which are actually metastable:
- Algorithmic stablecoins, the canonical example of which is Terra/luna. They are stable as long as the arbitrageurs have enough resource, but when selling pressure gets to be more than the arbitrageurs can handle, the coin will go to approximately zero.
- Backed stablecoins, which are like banks in that their "deposits" are much shorter-term than their assets. So, just like Silicon Valley Bank, they are subject to bank runs, but unlike SVB they don't have an FDIC or a Federal Reserve to bail them out so will go to approximately zero.
The system is secure as long as honest nodes collectively control more CPU power than any cooperating group of attacker nodes.Cooperation among an anonymous group protected Bitcoin during failures of decentralization by Alyssa Blackburn et al traces the early history of Bitcoin's centralization. On 13th June 2014 GHash controlled 51% of the Bitcoin mining power. The miners understood that this looked bad, so they split into a few large pools. But there is nothing to stop these pools coordinating their activities. As Vitalik Buterin wrote:
can we really say that the uncoordinated choice model is realistic when 90% of the Bitcoin network’s mining power is well-coordinated enough to show up together at the same conference?and Makarov and Schoar wrote:
Six out of the largest mining pools are registered in China and have strong ties to Bitmain Technologies, which is the largest producer of Bitcoin mining hardware
For almost the entire history of Bitcoin no more than 5 pools have controlled 51% of the Bitcoin mining power. For almost the entire history of Ethereum's use of Proof-of-Work even fewer pools, often only two, have controlled 51% of the mining power. The switch to Proof-of-Stake has not changed this. And note that Proof-of-Stake conforms to Mark 4:25:
For he that hath, to him shall be given: and he that hath not, from him shall be taken even that which he hath.and thus ensures that the Gini coefficient of ETH will continue to increase.
Here is the Ontario Securities Commission report on Quadriga CX. David Gerard summarizes:
The upshot is what you expected — Quadriga was a massive scam all the way down, and Gerald Cotten was running it like a Ponzi scheme, paying out withdrawals only with deposits, to fund his lifestyle. Cotten also traded on the platform, front-running his customers. He blew another CAD$28 million of cryptos trading on other exchanges.
The OSC bends over backwards to say “not all crypto exchanges” — though I remind you all of the Bitwise report to the SEC [PDF] about how 95% of reported exchange volume was obviously fake, because the numbers weren’t statistically plausible.
The story of Tether's $850M is complicated. Between 2014 and 2018, as a way to work around not having access to banking, Bitfinex used Crypto Capital as a front. Then the authorities in Poland seized Crypto Capital's accounts for money laundering, leaving an $850M hole in Bitfinex' accounts. Then Bitfinex used Tether's reserves, which were allegedly backing the stablecoin, to plug the hole in its accounts, which meant that USDT was no longer backed by a dollar in a bank. In 2021 Tether and Bitfinex settled with the CFTC for their false claims about this. Later that year the DoJ sent letters warning Tether and its executives that they were under investigation for the crime of lying to banks. In 2022 Reginald Fowler pled guilty to five counts including bank fraud for setting up bank accounts for Crypto Capital:
A former minority owner of the National Football League’s Minnesota Vikings should spend seven years behind bars and forfeit more than $740 million after admitting he helped cryptocurrency exchanges avoid money-laundering rules, prosecutors told a federal judge in New York.Bitfinex allege that Fowler converted $385M of the money to his personal uses, although skepticism is warranted.
The list of Coinbase's problems from The Exchange You Can Trust:
- Trying To Sell Unregistered Securities
- Fiasco In India
- Misleading Customers About Their Funds And Keys
- "Losing Money Running A Casino"
- NFT Marketplace Fiasco
- Tolerating Insider Trading
- Actually Selling Unregistered Securities
- Forcing Arbitration On Customers
- Coinbase bonds trading at 50c on the dollar.
- Coinbase laid off at least 1160 staff in 2022.
- Coinbase stock ended 2022 89.3% down from their high.
- Coinbase lost $1.1B in Q2 and $545M in Q3 2022.
- Coinbase suffered massive withdrawals. $248 million in customer stablecoins was withdrawn from Coinbase just on July 15 — half the stablecoin holdings as of that day.
Bittrex regularly asked issuers to remove “problematic statements” from their marketing materials—statements indicating that the asset was marketed as a security—as a prerequisite for making the issuers’ crypto assets available for trading on the Bittrex Platform. Bittrex unofficially dubbed this practice the “problematic statement cleanup.”Some at least of the "cleaned up" assets trade also on Coinbase. Coinbase appears to be relocating to Bermuda, in anticipation of being excluded from the US for money laundering.
- Genesis is part of Barry Silbert's Digital Currency Group. Genesis loaned 3AC $2.36B, so when 3AC went bankrupt Genesis was in trouble. So DCG made Genesis a non-callable loan of $1.1B at 1%! Then FTX went bankrupt and Genesis suspended withdrawals. Gemini had at least $700M of its customers' funds loaned to Genesis, so they were in trouble too. These loans were from Gemini's Earn program, which promised 8% returns, so is clearly a security. Gemini and Genesis are fighting, and the SEC has sued both of them for selling unregistered securities.
The SEC's reasons for forbidding Bitcoin ETFs include:
- “wash” trading,
- persons with a dominant position in bitcoin manipulating bitcoin pricing,
- hacking of the bitcoin network and trading platforms,
- malicious control of the bitcoin network,
- trading based on material, non-public information, including the dissemination of false and misleading information,
- manipulative activity involving the purported “stablecoin” Tether (“USDT”),
- fraud and manipulation at bitcoin trading platforms.
Vildana Hajric's A Closer Look at Bitcoin’s Rally Suggests the Depth of Demand Is Deceptive shows that there is very little liquidity in the BTC-USD pair, all the trading that has driven BTC back around $30K is in BTC-USDT and other metastablecoins, especially those pairs for which Binance offered zero-fee trades:
But isolating just the Bitcoin-dollar trade pair — which trades on exchanges like Coinbase and Gemini — shows volume was the lowest since 2020, the researcher said. During that time, regulators cracked down on the industry with a number of lawsuits and actions.
The Bitcoin-dollar pair measure may be a better way of representing what volumes actually looked like without zero-fee trading during the first three months of the year and shows a “starkly different trend,” according to Kaiko’s Clara Medalie, who published research on the topic alongside with Conor Ryder, research analyst at the firm.
Retail activity has dropped off across the globe, with global exchange traffic down 25% since the summer, according to new research from K33 and EY Norway. Their findings say that from June to August 2022, crypto exchanges clocked 630 million visits. Last quarter, that number fell to 475 million. In addition, crypto-related websites have seen plummeting traffic when compared with last summer.I wrote about the lack of retail money coming into cryptocurrencies last November in Greater Fool Supply-Chain Crisis, and Hajric's post supports my argument. The spot market has been pumped back to levels the miners can live with and the much bigger derivative market doesn't care; all they are interested in is the huge volatility.
Noelle Acheson, author of the Crypto Is Macro Now newsletter, said that while activity is climbing in crypto derivatives, the same is not yet true for the so-called spot, or cash market.
Last Decemeber I modeled the cryptocurrency ecosystem as a black box and wrote:
A rough estimate of the total amount of fiat currency that could be extracted from the black box can be made by taking the "attestations" of the major stablecoins at face value and summing them; there are unlikely to be large stores of fiat in the box that haven't been converted to stablecoins. This gets us $66.2B (USDT) + $44.2B (USDC) + $17.4B (BUSD) + $0.7B (USDD) = $128.5B, against a current total "market cap" of cryptocurrencies at around $800B.In other words, estimates of cryptocurrencies' "market cap" should be deflated by a factor of about 6 to get the amount of "real money" they represent.
