Two Estonian nationals, Sergei Potapenko and Ivan Turõgin, have pleaded guilty to operating a crypto Ponzi scheme through their cloud mining service, HashFlare. The U.S. Department of Justice (DOJ) announced that the scheme, which ran from 2015 to 2019, defrauded investors of approximately $577 million.
HashFlare allowed users to purchase mining contracts to rent computing power for mining cryptocurrencies like Bitcoin and Ether.
In addition to the fraudulent mining operations, Potapenko and Turõgin promoted a non-existent cryptocurrency bank called Polybius, which failed to deliver promised dividends to investors. The fraudulent activities resulted in hundreds of thousands of victims worldwide, including many in the United States.
The defendants were arrested in Tallinn, Estonia, in November 2022, and subsequently extradited to the U.S. where they faced multiple charges, including conspiracy to commit wire fraud and money laundering.
As part of their plea agreement, both men agreed to forfeit assets valued at over $400 million, which will be used to compensate victims in a forthcoming remission process.
The DOJ has stated that Potapenko and Turõgin face a maximum of 20 years in prison when they are sentenced on May 8. The investigation was led by the FBI’s Seattle field office, with assistance from various U.S. officials and the Estonian authorities, including the Ministry of Justice and Digital Affairs.
