OneCoin (Ruja Ignatova): OneCoin: Ponzi-style crypto fraud reported at over $4B; founder Ruja Ignatova still at large
OneCoin was a multi-level marketing and Ponzi-style scheme that sold packages of a 'cryptocurrency' with no genuine blockchain, according to U.S. authorities. Authorities say it took in more than $4 billion worldwide, mostly from 2014 to 2016, and continued through 2019. Founder Ruja Ignatova disappeared on 25 October 2017, and recovery efforts are ongoing through forfeiture, freezing orders and victim compensation processes.

What happened
According to U.S. authorities and FBI materials, OneCoin was launched in 2014 by Ruja Ignatova and associates and marketed as a legitimate cryptocurrency and a 'Bitcoin killer'. Prosecutors say the scheme took in more than $4 billion worldwide, with more than $4 billion between Q4 2014 and Q4 2016 alone, and the DOJ later said it continued through 2019.
Reporting says the 'facade started cracking' in 2016, when investors had difficulty selling OneCoins and recovering their money. Enforcement actions followed across several countries: reported arrests at a recruitment event in India (23 April 2017), a U.S. charge against Ignatova in October 2017, and a reported Bulgarian police raid on Sofia offices in January 2018 with German police and Europol.
Ignatova reportedly boarded a flight from Sofia to Athens on 25 October 2017 and has not been located since. The FBI added her to its Ten Most Wanted list, and a $5 million reward was later reported (The Register, June 2024). Prosecutors say Karl Sebastian Greenwood was sentenced to 20 years in 2023 for his role.
How it worked
According to investigators and civil litigants, OneCoin had no real, transferable blockchain-backed asset and no open-market price discovery. Its 'price' was set internally by the company; prosecutors say it was arbitrarily set, reaching about EUR 29.95 by January 2019 in the scheme's own records.
Victims were reportedly told to wire money to OneCoin accounts to buy packages. Members earned commissions for recruiting new buyers, and prosecutors say newer investors' money was used to support earlier payouts and the operation, which is the core Ponzi/pyramid mechanic. Users reportedly could only transfer coins within a closed system in limited quantities, so they could not realistically cash out.
