Court imposes probation on Estonian crypto entrepreneurs in American legal decision
=====================================================================
The US justice system has sentenced two Estonian crypto entrepreneurs, Sergei Potapenko and Ivan Turogin, for their involvement in a $577 million Ponzi scheme that ran from 2015 to 2019. The duo orchestrated the HashFlare scam, a fake cryptocurrency mining company that promised investors profits but delivered only a tiny fraction of the cryptocurrency mined.
The fraudulent operation used new investors' funds to pay returns to earlier investors, creating an illusion of profitability through fabricated online dashboards and fake mining statistics. The scammers diverted investors' money into personal purchases such as luxury cars, real estate, expensive jewelry, and private jet trips.
In addition to HashFlare, the duo also ran Polybius Bank, a fake virtual currency bank that raised $25 million in an ICO but never operated legitimately.
Potapenko and Turogin were arrested in 2023 after complex extradition proceedings from Estonia to the United States. They pleaded guilty to conspiracy to commit wire fraud in early 2025 and agreed to forfeit over $400 million in assets, including real estate, cryptocurrency, luxury vehicles, and mining equipment.
The Seattle federal court sentenced the pair to 16 months in prison, but since they had already served that time in custody since their 2022 indictment, they avoided further prison time. The court imposed a $25,000 fine each, 360 hours of community service, supervised release in Estonia, and ordered forfeiture of over $450 million in illicit assets.
The Department of Justice described the fraud as one of the largest cryptocurrency scams and has indicated consideration of appealing the lenient sentence.
Key details of the case:
- Crime: Conspiracy to commit wire fraud (Ponzi scheme)
- Fraud amount: $577 million
- Operation period: 2015–2019
- Location of operation: Estonia (arrested and extradited to U.S.)
- Sentence: 16 months time served (no additional prison)
- Additional penalties: $25,000 fine, 360 hours community service, supervised release
- Asset forfeiture: Over $450 million in cash, real estate, vehicles, luxury goods
- DOJ stance: May appeal lenient sentence
Despite the lenient sentence, the US Department of Justice may appeal the decision due to the magnitude of the fraud. Potapenko and Turogin's Ponzi scheme remains one of the largest crypto scams in history.
- The business activities of Sergei Potapenko and Ivan Turogin, who were involved in a $577 million Ponzi scheme, were not confined to just the crypto industry; they also operated a fake virtual currency bank named Polybius Bank.
- The sentencing of Potapenko and Turogin for their crime in the 'general-news' category, which includes the 'crime-and-justice' sector, highlights an instance where the US justice system has demonstrated its commitment to pursuing and penalizing those who engage in financial fraud, even when such activities involve innovative technology like cryptocurrency.
