Estonian Nationals Admit to $577M Cryptocurrency Fraud That Scammed U.S. Citizens

Sergei Potapenko and Ivan Turõgin

Two Estonian nationals have pleaded guilty in the United States to operating a $577 million cryptocurrency Ponzi scheme through their company, HashFlare.

The scam deceived hundreds of thousands of investors worldwide, falsely promising cryptocurrency mining profits.

How the Scheme Worked

Between 2015 and 2019, Sergei Potapenko and Ivan Turõgin, both 40, sold contracts through HashFlare, claiming customers would earn a share of cryptocurrency mined by the company.

In reality, HashFlare lacked the computing power to mine the promised amounts.

Investors were shown fake profit data on a web-based dashboard while Potapenko and Turõgin pocketed the funds, using them to buy real estate, luxury cars, and cryptocurrency investments.

Legal Consequences & Victim Compensation
