HashFlare Founders Sentenced to 16 Months Time Served in Crypto Fraud Case

Highlights:

• HashFlare founders have been sentenced to time served and ordered to pay fines.
• Prosecutors have called the case the largest fraud trial in Seattle history.
• Authorities will release details on how victims will receive compensation from seized assets.

HashFlare founders Sergei Potapenko and Ivan Turõgin have avoided additional prison time after admitting to their roles in a $577 million Ponzi scheme. Judge Robert Lasnik of the Seattle Federal Court credited the 16 months they had already spent in custody since their arrest in Estonia.

The judge ordered each of the two founders to pay a $25,000 fine and complete 360 hours of community service. They will serve supervised release in Estonia. The Department of Justice confirmed that it is reviewing the case to decide whether to appeal the sentence. Prosecutors had requested a 10-year term, while the defendants asked for time served.

Authorities arrested the pair in Estonia and later extradited them to the United States in May 2024. The founders pleaded guilty to conspiracy to commit wire fraud. In February, they agreed to forfeit more than $450 million in assets, including real estate, cryptocurrency, luxury vehicles, and mining equipment. These assets form part of the potential repayment to victims once the process begins.

HashFlare Founders Sentenced in Seattle’s Largest Fraud Trial

Prosecutors alleged that HashFlare sold mining contracts worth over $577 million while showing customers fake dashboards. These dashboards displayed mining capacity and earnings that did not exist. Prosecutors argued the operation matched the structure of a Ponzi scheme.

Acting U.S. Attorney Teal Miller said the defendants used millions for personal purchases, including cryptocurrency, high-end real estate, luxury cars, jewelry, and more than a dozen private jet trips. Miller said many victims experienced financial and emotional harm because they believed they were investing in genuine cryptocurrency mining.

Defense attorneys disagreed, arguing that most customers recovered their money. They said 390,000 of the 440,000 customers withdrew around $2.3 billion after purchasing contracts worth $487 million. Defense lawyer Andery Spektor admitted that HashFlare overstated mining output but insisted that no one suffered financial harm.

Judge Lasnik accepted that victims recovered significant amounts through forfeited assets, though prosecutors maintained that the damage was real. Prosecutors also said the defense used expert analysis focused on investor earnings instead of measuring actual losses, which did not reflect the harm caused. In a closely related crypto case, Do Kwon pleaded guilty to two counts after changing his plea. Kwon confessed that he intentionally lied about the stability of TerraUSD.

Victim Repayment Plan Remains Undecided

Authorities have not finalized the process for distributing forfeited assets to victims. The Department of Justice said it will release details about the remission process at a later date. The seized assets are expected to be used for compensation, though the timeline remains unclear.

Prosecutors also accused the pair of raising $25 million in 2017 for the creation of a digital bank called Polybus, which never became operational. In April, the defendants received a letter from the Department of Homeland Security instructing them to leave the United States, despite a court order to remain. They have expressed interest in returning to Estonia and will serve their supervised release there once the case’s remaining matters conclude.
