Alexander Vinnik: The BTC-e Laundromat

In late July 2017 Greek police walked up to a Russian tourist on holiday with his family at a beach resort in northern Greece and arrested him on an American warrant. The tourist was Alexander Vinnik, an IT specialist then in his late thirties. Within days, the website of BTC-e, one of the oldest bitcoin exchanges in the world, went dark. A US indictment unsealed that week accused Vinnik of running it as a laundromat for hackers, drug dealers and extortionists.

An exchange, in crypto, is the equivalent of a broker: customers send in ordinary money or digital coins and trade one for the other. A regulated broker checks a customer's passport and watches for dirty money. BTC-e, prosecutors said, did neither. It asked for an email address and little else.

What followed took almost eight years, three countries and a prisoner swap. It ended with Vinnik back in Russia, a free man, while the US government kept the exchange's money.

The numbers

The US Department of Justice (DOJ) says BTC-e processed more than $9 billion of transactions between 2011 and July 2017 and served more than a million users, many of them in the United States. The 2017 indictment put the bitcoin it received at more than $4 billion, the figure most headlines still use.

The same week as the arrest, the Financial Crimes Enforcement Network (FinCEN), the US Treasury unit that polices money laundering, fined BTC-e about $110 million and Vinnik personally $12 million for wilfully breaking anti-money laundering law.

Prosecutors described the customer base in blunt terms: proceeds of computer hacks, ransomware, identity theft, corrupt officials and drug rings. Ransomware is software that locks a victim's files until a ransom is paid, usually in bitcoin. A study presented at the Black Hat security conference in July 2017 by researchers from Google, Chainalysis, New York University and UC San Diego traced about $16 million in ransom payments from 19,750 likely victims and found that 95 percent of the payments they could follow were cashed out through BTC-e. That figure covers the payments those researchers traced, not every ransom ever paid, but it showed where the money went to turn back into cash.

The Mt. Gox connection

BTC-e's name was also tied to the biggest theft of the early bitcoin era. Mt. Gox, the Tokyo exchange that collapsed in 2014, lost roughly 850,000 bitcoin. The 2017 indictment accused Vinnik of receiving and laundering funds stolen from Mt. Gox.

In June 2023 the DOJ went further. It charged two other Russian nationals, Alexey Bilyuchenko and Aleksandr Verner, with conspiring to launder about 647,000 bitcoin stolen in a hack of Mt. Gox's servers that, prosecutors said, began in September 2011. Bilyuchenko was also charged with helping Vinnik run BTC-e from 2011 to 2017. Neither man has been brought to a US court, and both are believed to be in Russia, out of reach.

Vinnik always said he was a technical employee, not the boss. He told French judges that he carried out instructions from BTC-e's directors.

Three countries, one prisoner

After the arrest, three governments asked Greece for Vinnik. The United States wanted him for money laundering. France wanted him for allegedly extorting French victims with Locky, a strain of ransomware that hit thousands of computers there. Russia asked for him on a far smaller fraud case. Greek courts approved the American request first, but Greece sent him to France in January 2020.

In December 2020 a Paris court found Vinnik guilty of money laundering and sentenced him to five years in prison and 100,000 euros in fines. It acquitted him of extortion and of belonging to a criminal organisation, and prosecutors did not get the ten years they had asked for.

France then returned him to Greece, and in August 2022 Greece extradited him to the United States. On 3 May 2024, in federal court in San Francisco, Vinnik pleaded guilty to conspiracy to commit money laundering. In the plea he accepted responsibility for losses of at least $121 million. The charge carried up to 20 years in prison, and he waited in custody for a sentencing date that was pushed from January 2025 to June 2025.

The swap

Sentencing never came. In February 2025 Russia freed Marc Fogel, an American history teacher arrested at a Moscow airport in August 2021 with a small amount of medical marijuana and sentenced to 14 years. The US had classed Fogel as wrongfully detained. President Donald Trump greeted him at the White House on 11 February.

The next day, the Kremlin confirmed that a Russian prisoner held in the US would be released in return, and Vinnik's French lawyer, Frederic Belot, confirmed to the Russian news agency TASS that his client was the one. Vinnik was flown out of the United States and arrived in Moscow on 13 February 2025. According to Bloomberg Law, the US Attorney's office then dismissed his indictment, so the guilty plea never turned into a sentence. He became at least the third Russian facing US cybercrime charges to go home in a prisoner swap, after Roman Seleznev and Vladislav Klyushin in August 2024.

Back in Russia, the police dropped their own search for him. Forklog, citing sources at TASS, reported that the Interior Ministry removed him from its wanted list because no claims against him remained.

Where the money went

The coins did not go home with him. In June 2025 the DOJ filed a civil forfeiture case in Washington, DC, a lawsuit against property rather than a person, claiming all the cryptocurrency that sat in BTC-e's operating wallets on 25 July 2017, plus bank accounts linked to the exchange in New Zealand, Australia and the Czech Republic. The deadline for anyone to contest it passed on 2 September 2025. Vinnik has since told former customers of BTC-e, and of its successor WEX, to seek their money from the US government.

One BTC-e case is still open. Aliaksandr Klimenka, a Belarusian national arrested in Latvia in December 2023 and accused of helping run the exchange, asked a judge to throw out his charges because the swap had removed a witness who might have cleared him. Judge Susan Illston refused in June 2025, writing that he had not explained how Vinnik's testimony would help him. According to the legal news service MLex, his trial is set to begin in November 2026. Klimenka denies the charges.

The result is a lopsided record. The exchange is gone, its money is in US hands, and FinCEN's penalties stand. The man who admitted helping run it served his time in France, pleaded guilty in America and was never sentenced there.
