HashFlare Founders Avoid Prison in $577M Crypto Fraud Case
Sergei Potapenko and Ivan Turõgin, founders of the crypto mining platform HashFlare, were sentenced to time served in a Seattle federal court on August 19, 2025, for their roles in a $577 million Ponzi scheme. Arrested in Estonia in November 2022, the duo spent 16 months in custody before extradition to the U.S., where they pleaded guilty to wire fraud conspiracy. Judge Robert Lasnik ordered $25,000 fines and 360 hours of community service each, to be served in Estonia. The Department of Justice, which sought a 10-year prison term, is considering an appeal, citing the case as Seattle’s largest fraud prosecution.From 2015 to 2019, HashFlare defrauded 440,000 investors by displaying fake mining dashboards and using new investors’ funds to pay earlier ones. The founders diverted millions for personal luxury, including Bitcoin, real estate, and private jets. Their plea deal included forfeiting $400 million, and their lawyers noted that 390,000 customers withdrew $2.3 billion, mitigating losses. This likely influenced the lenient sentence. A deportation mix-up added drama, with the duo ordered to leave the U.S. despite a court mandate to stay. The case highlights the risks of unregulated crypto ventures and the challenges of prosecuting such fraud.
