More than 120,000 bitcoin were stolen in a 2016 breach of Bitfinex. Seven years later the perpetrator pleaded guilty. And Thursday he was sentenced to a five-year prison term, reports the Associated Press: Ilya Lichtenstein masterminded one of the largest-ever thefts from a virtual currency exchange before he and his wife, Heather Rhiannon Morgan, carried out an elaborate scheme to liquidate the stolen funds, according to federal prosecutors... "Over half a decade, the defendant engaged in what IRS agents described as the most complicated money laundering techniques they had seen to date," prosecutors wrote... The couple successfully laundered about 21 percent of the funds stolen from Bitfinex. The laundered money was worth at least $14 million at 2016 prices. Its value would have exceeded $1 billion at the time of their 2022 arrest. Authorities seized the remaining funds, collectively valued at over $6 billion at current prices... An attorney for Bitfinex said the hack "devastated" its finances and its reputation with its customers, with the stolen funds accounting for approximately 36% of the company's assets at the time of theft. "Bitfinex had to take unprecedented and immediate action to ensure that any losses from the Hack would ultimately be borne by Bitfinex and its shareholders alone, not its customers," the lawyer, Barry Berke, wrote in a letter to the judge. A prosecutor said Lichtenstein immediately began cooperating with federal authorities after his arrest, helping them with other cybercrime investigations. Over 96% of the stolen funds have been recovered, with help from Lichtenstein, according to defense attorney Samson Enzer. The "vast bulk" of the stolen money was never spent, the lawyer said. Lichtenstein also "pleaded with the judge to spare his wife from prison, blaming himself for her involvement," according to the article. His wife — a rap artist who records under the name Razzlekhan — will be sentenced Monday, but has pleaded guilty to the same charge, and prosecutors are recommending an 18-month sentence.

Cryptocurrency backers continue to bid up Bitcoin prices, pushing the digital token to a new high of about $84,000 on Monday. The New York Times: The cryptocurrency has surged since Election Day, on investor hopes that President-elect Donald J. Trump and his appointees would be friendlier to the industry after the Biden administration's aggressive enforcement of securities law that targeted several crypto companies. Cryptocurrencies have become a major component of the so-called Trump trade. Bitcoin exchange-traded funds, which got the regulatory green light to trade this year, have been booming over the past week. Crypto-related companies have also jumped in value: Riot Platforms, a Bitcoin miner, is up 68 percent since Election Day and Coinbase, a crypto exchange, is up 69 percent over the same period.

Leading fintech and digital asset firms, including Robinhood, Kraken and Galaxy Digital, have introduced a joint stablecoin pegged to the U.S. dollar. Called the Global Dollar Network, it seeks to enhance the stablecoin market by lowering transaction costs, boosting consumer protections, and facilitating cross-border transactions with rewards for institutional participants. Crypto Briefing reports: The network will utilize Paxos's new stablecoin, the Global Dollar (USDG), which complies with the Monetary Authority of Singapore's upcoming stablecoin framework. USDG is designed to return yield on reserve assets to participants who contribute to its adoption, encouraging the development of crypto and financial solutions using the token. The Global Dollar Network aims to address shortcomings in the stablecoin market, such as high transaction costs and limited consumer protections. The network has opened an invite-only phase for select custodians, exchanges, payment processors, merchants, and banks to develop new solutions using USDG. Initial distribution is available on Anchorage Digital, Galaxy Digital, Kraken, and Paxos platforms, with plans to expand access through additional partners in the coming months.

The feds have indicted Aleksei Andriunin, a 26-year-old Russian national and founder of Gotbit, on charges of wire fraud and conspiracy to commit market manipulation. Crypto News reports: According to the U.S. Attorney's Office, the indictment alleges that Andriunin and his firm participated in a long-running scheme to artificially boost trading volumes for various cryptocurrency companies, including some based in the United States, to make them appear more popular and increase their trading value. Andriunin allegedly led these activities between 2018 and 2024 as Gotbit's CEO. He could face up to 20 years in prison, additional fines, and asset forfeiture if convicted, according to the U.S. Attorney's Office. Prosecutors say the scheme involved "wash trading," where the firm used its software to make fake trades that inflated a cryptocurrency's trading volume. This practice, called market manipulation, can mislead investors by giving the impression that demand for a particular cryptocurrency is higher than it actually is. Wash trades are illegal in traditional finance and are considered fraudulent because they deceive investors and manipulate market behavior. Court documents also identify Gotbit's two directors, Fedor Kedrov and Qawi Jalili, as co-conspirators. The indictment claims Gotbit documented these activities in detailed records, tracking differences between genuine and artificial trading volumes. The firm allegedly pitched these services to prospective clients, explaining how Gotbit's tactics would bypass detection on public blockchains, where transactions are recorded transparently. The U.S. Department of Justice has announced that it seized over $25 million worth of cryptocurrency assets connected to these schemes and made four arrests across multiple firms. If you've been following the crypto industry, you're probably familiar with "pump-and-dump" schemes that have popped up throughout the years. Although it's a form of market manipulation, it's not quite the same as "wash trading." In a pump-and-dump scheme, the perpetrator artificially inflates the price of a security (often a low-priced or thinly traded stock) by spreading misleading or exaggerated information to attract other buyers, who then drive up the price. Once the price has risen due to increased demand, the manipulators "dump" their shares at the inflated price, selling to the new buyers and pocketing the profits. The price typically crashes after the dump, leaving unsuspecting investors with overvalued shares and significant losses. Wash trading, on the other hand, involves simultaneously buying and selling of the same asset to create the illusion of higher trading volume and activity. The purpose is to mislead other investors about the asset's liquidity and demand, often giving the impression that it is more popular or actively traded than it actually is. Wash trades usually occur without real changes in ownership or price movement, as the buyer and seller may even be the same person or entity. This tactic can manipulate prices indirectly by creating a perception of interest, but it does not involve a direct inflation followed by a sell-off, like a pump-and-dump scheme.

Russia has enacted a new law expanding control over cryptocurrency mining, granting multiple federal agencies access to digital currency identifier addresses, among other things. The country is also advancing its regulatory framework and experimenting with crypto in international trade. From a report: Taking effect on Nov. 1, the legislation includes several amendments designed to strengthen oversight and impose limitations on crypto mining activities based on regional needs. The law enables the Russian government to implement mining restrictions by location and define specific procedures and circumstances for banning mining operations. A notable provision in the law gives the government the power to stop digital currency mining pools from functioning in certain areas. Additionally, the government now has the authority to regulate infrastructure providers supporting mining operations. This legislation also grants multiple federal agencies, beyond the Federal Financial Monitoring Service (Rosfinmonitoring), access to digital currency identifier addresses. This expansion includes federal executive agencies and law enforcement, bolstering their capability to track transactions that may be linked to money laundering or terrorist financing activities. Moreover, the amendments transfer responsibility for the national mining register from the Ministry of Digital Development to the Federal Tax Service, which will now oversee mining registrations for businesses and remove those with repeated infractions. While individual miners can continue without registering if they adhere to specific electricity consumption limits, companies and individual entrepreneurs must comply with new registration requirements.

An anonymous reader quotes a report from Wired: When Canadian developer Peter Todd found out that a new HBO documentary, Money Electric: The Bitcoin Mystery, was set to identify him as Satoshi Nakamoto, the creator of Bitcoin, he was mostly just pissed. "This was clearly going to be a circus," Todd told WIRED in an email. The identity of the person -- or people -- who created Bitcoin has been the subject of speculation since December 2010, when they disappeared from public view. The mystery has proved all the more irresistible for the trove of bitcoin Satoshi is widely believed to have controlled, suspected to be worth many billions of dollars today. When the documentary was released on October 8, Todd joined a long line of alleged Satoshis. Documentary maker Cullen Hoback, who in a previous film claimed to have identified the individual behind QAnon, laid out his theory to Todd on camera. The confrontation would become the climactic scene of the documentary. But Todd nonetheless claims he didn't see it coming; he alleges he was left with the impression the film was about the history of Bitcoin, not the identity of its creator. Since the documentary aired, Todd has repeatedly and categorically denied that he created Bitcoin: "For the record, I am not Satoshi," he alleges. "I think Cullen made the Satoshi accusation for marketing. He needed a way to get attention for his film." For his part, Hoback remains confident in his conclusions. The various denials and deflections from Todd, he claims, are part of a grand and layered misdirection. "While of course we can't outright say he is Satoshi, I think that we make a very strong case," says Hoback. Whatever the truth, Todd will now bear the burden of having been unmasked as Satoshi. He has gone into hiding. [...] Todd expects that "continued harassment by crazy people" will become the indefinite status quo. But he says the potential personal safety implications are his chief concern -- and the reason he has gone into hiding. "Obviously, falsely claiming that ordinary people of ordinary wealth are extraordinarily rich exposes them to threats like robbery and kidnapping," says Todd. "Not only is the question dumb, it's dangerous. Satoshi obviously didn't want to be found, for good reasons, and no one should help people trying to find Satoshi." "I think the idea that it puts their life [at risk] is a little overblown," says Hoback. "This person is potentially on track to become the wealthiest on Earth." "If countries are considering adopting this in their treasuries or making it legal tender, the idea that there's potentially this anonymous figure out there who controls one twentieth of the total supply of digital gold is pretty important."

The blockchain-based identity verification company founded by Sam Altman is now called "World." It also unveiled a new version of the "Orb" biometric devices the company uses to scan users' eyes. CoinTelegraph reports: World, as it's now known, also revealed a slew of other updates including a new version of its Orb biometric scanning devices, new options for identity verification and partnership integrations with popular apps including FaceTime, WhatsApp, and Zoom. [...] The new Orb, powered by Nvidia hardware, will be more efficient and "five times" more powerful than its predecessor with a smaller footprint and fewer parts. The company also said the new Orb would eventually be available in self-service kiosks in some markets. World also announced that users will soon be able to verify their identity through methods other than the firm's Orb hardware. Through a program called World ID Credentials, the company says users with NFC-enabled government issued passports will allow them to verify their identity on the World app. Another major announcement came in the form of World ID Deep Face, a service the company claims has "solved deepfakes." According to the company, its software can be implemented into just about any app where video can be uploaded or streamed to determine whether videos featuring verified persons are real or have been faked using AI. Finally, the company also announced that so far 15 million users have signed up for its World app service; among them, seven million are verified.

Donald Trump's new crypto project, World Liberty Financial, had a rocky start today with frequent website outages during its token sale. According to CNBC, only about 4% of registered investors have bought tokens, and the project sold less than 3% of the 20 billion tokens available. From the report: WLF's website suffered regular and lengthy outages for much of the morning and early afternoon, contributing to a limited number of sales. Only about 4,300 unique walled addresses hold the token as of Tuesday afternoon, according to blockchain data tracked by Etherscan, representing roughly 4% of the total number of people who registered. The platform says it has sold more than 532 million tokens at 15 cents per token. That is less than 3% of the 20 billion tokens made available for public sale. Over the course of the day, the website frequently showed a page saying, "We are under maintenance." The glitchy launch is a potential setback to the Republican presidential nominee with just three weeks until the election. Trump and his family have been touting the project since August, branding it as "The DeFiant Ones," a play on DeFi, which is short for decentralized finance.

The man identified as Bitcoin creator Satoshi Nakamoto in a new HBO documentary has something to say: Wrong again, world. From a report: In the just-released HBO film on the history of the world's biggest digital currency -- Money Electric: The Bitcoin Mystery -- documentary filmmaker Cullen Hoback comes to the conclusion that the anonymous creator of Bitcoin was none other than a long-time member of the community and early Bitcoin developer Peter Todd. Todd dismissed the claim in the documentary, released yesterday, and denied it again when asked by The Register. "[Hoback's] evidence for me being Satoshi is the same kind of coincidence-based, circumstantial thinking that fuels conspiracies like QAnon," Todd told us in an email. "Which is ironic, given that [Hoback's] previous big project was a documentary on QAnon. He clearly didn't try to debunk his theories either." Hoback's previous project -- Q: Into the Storm -- aimed to unmask the person behind QAnon, perhaps giving him an interest in uncovering the identity of Satoshi Nakamoto. Todd, however, thinks Hoback was just trying to drum up interest in his new film. "I think [Hoback] only included the Satoshi claim as a marketing ploy: he was really creating a documentary about Bitcoin, and needed a hook to get media attention," Todd said. "He picked me to accuse mainly because I was an unlikely candidate, which helped drum up even more attention. I don't think he had any interest in finding the real truth."

Après plus de 15 années de mystère, HBO prétend avoir trouvé l'identité du mystérieux Satoshi Nakamoto. La théorie a récemment été dévoilée dans un documentaire sur le Bitcoin diffusé dans la nuit de mardi à mercredi.

A new HBO documentary claims Canadian developer Peter Todd is Satoshi Nakamoto, the pseudonymous founder of bitcoin. The documentary's director, Emmy-nominated filmmaker Cullen Hoback, "comes to the conclusion by stitching together old clues and new ones," reports Politico. In the film's finale, Hoback confronted Todd and said: "It seems like you had these deep insights into bitcoin at the time?" Todd replies: "Well, yeah, I'm Satoshi Nakamoto." From the report: The admission, however, is not necessarily a smoking gun. Todd, who is a vocal backer of Ukraine and Israel on his X feed, is known to invoke the claim "I am Satoshi" as an expression of solidarity with the creator's bid for privacy. In an email to CoinDesk prior to the documentary's release, Todd reportedly denied he was the bitcoin creator: "Of course I'm not Satoshi," he said. If Todd is widely accepted as bitcoin's creator, the revelation would end more than a decade of speculation over the identity of a person whose work spawned a global, multibillion-dollar craze for digital currencies: a mania that has pushed back the frontiers of finance but also enabled widespread fraud and other illicit activities. Todd is not unknown to enthusiasts of the stateless money system. As a longstanding bitcoin core developer known for communicating publicly with "Satoshi" before his disappearance from crypto forums in 2010, his name has always carried weight in the community. But he was rarely considered a prime suspect. A 39-year-old graduate of Ontario College of Art and Design in Toronto, Todd would have been 23 when the famous bitcoin white paper that first laid out the vision for the decentralized money system was being completed. Todd previously told a podcast he was about 15 years old when he first started communicating with key crypto influencers, known as the cypherpunks. "In investigations like these, digital forensics can only take you so far; they're like a compass," Hoback told POLITICO before the documentary aired. "Real answers can only be found offline."

On Wednesday, the SEC filed (PDF) to appeal a 2023 court ruling that determined XRP is not considered a security when sold to retail investors on exchanges. The announcement sent the price of XRP tumbling more than 8%. "XRP, which was created by the founders of Ripple, is the native token of the open source XRP Ledger, which Ripple uses in its cross-border payments business," notes CNBC. "It is the fifth-largest coin by market cap, excluding stablecoins Tether (USDT) and USD Coin (USDC)." CNBC reports: Ripple, the largest holder of XRP coins, scored a partial victory last summer after a three-year battle with the SEC. U.S. District Judge Analisa Torres handed down the decision, which was hailed as a landmark win for the crypto industry. Still, while XRP isn't considered a security when sold to retail investors on exchanges, it is considered an unregistered security offering if sold to institutional investors. Ripple declined to comment but referred to Wednesday evening posts on X by CEO Brad Garlinghouse and chief legal officer Stuart Alderoty. Alderoty said the company is evaluating whether to file a cross appeal, and called the SEC's decision to appeal "disappointing, but not surprising." The SEC, under Chair Gary Gensler, has become notorious for its refusal to provide clear guidance for crypto businesses, instead opting to regulate by enforcement actions. "XRP's status as a non-security is the law of the land today - and that does not change even in the face of this misguided - and infuriating - appeal," Garlinghouse said on X.
