Two men have admitted operating a massive global cryptocurrency Ponzi scheme.
Estonians Sergei Potapenko and Ivan Turõgin, both 40, defrauded hundreds of thousands of people worldwide, including many in the United States.
The Cryptocurrency Scam Explained
Potapenko and Turõgin ran a business called HashFlare, which they marketed as a cryptocurrency mining service.
Cryptocurrency mining involves using powerful computers to generate digital currencies like Bitcoin.

How HashFlare Worked
- Selling Contracts: The defendants sold contracts to customers, claiming they would earn a share of cryptocurrency mined by HashFlare.
- Fake Mining Claims: Between 2015 and 2019, HashFlare generated over $577 million in sales. However, it did not have the computing power needed to perform the mining it promised.
- Falsified Data: HashFlare’s online dashboard showed customers inflated mining profits. In reality, most of the data was fabricated.
The Financial Impact
- $400 Million in Forfeited Assets: Potapenko and Turõgin have agreed to forfeit over $400 million worth of assets acquired through the fraudulent scheme. These assets will be made available for a future process to compensate victims.
- Luxury Purchases: The duo used the proceeds from the scam to buy real estate, luxury vehicles, and fund cryptocurrency and investment accounts.
