Not to be confused with the Onecoin issued by Chinese company Xunlei.
OneCoin is a fraudulentcryptocurrency scheme[1][2] conducted by offshore companies OneCoin Ltd, based in Bulgaria and[3] registered in Dubai, and OneLife Network Ltd (registered in Belize), both founded by Ruja Ignatova in concert with Sebastian Greenwood.[4] OneCoin is considered a Ponzi scheme due to its organisational structure of paying early investors using money obtained from newer ones. It was also a pyramid scheme due to the recruiting of investors without providing any actual product.[5] The company maintained its own database of coins rather than using a blockchain and had no mining process which limited its ability to release and circulate coins. Many of the people central to OneCoin had been previously involved in similar schemes and business malpractice.[6] OneCoin was described by The Times as "one of the biggest scams in history".[7]
US prosecutors alleged the scheme brought in approximately $4 billion worldwide.[8] In China, law enforcement recovered 1.7 billion yuan (US$267.5 million) while prosecuting 98 people.[9] Ruja Ignatova disappeared in 2017 when a secret US warrant was filed for her arrest, and her brother, Konstantin Ignatov, took her position at the company. Most of the leaders of the company disappeared or were arrested, though Ruja Ignatova has escaped arrest.[10] Greenwood was arrested in 2018,[11] as was Konstantin Ignatov in March 2019.[12] In November 2019, Konstantin Ignatov pleaded guilty to charges of money laundering and fraud. The total maximum sentence for the charges is 90 years in prison.[13] In 2022 Greenwood pleaded guilty, and in 2023 was sentenced to 20 years for wire fraud and money laundering.[14]
