The former head of legal and compliance at OneCoin pleaded guilty to fraud charges regarding her role in a cryptocurrency marketing scheme that generated more than $4 billion in sales and revenue.

Irina Dilkinska faces a maximum of 10 years in prison after pleading guilty to one count of conspiracy to commit wire fraud and one count of conspiracy to commit money laundering, the Department of Justice (DOJ) announced Thursday. Her sentencing is scheduled to take place in February.

OneCoin, started in 2014 in Bulgaria by Ruja Ignatova and Karl Sebastian Greenwood, relied on a pyramid scheme in which members were paid for recruiting others. Dilkinska helped solicit individuals to invest in OneCoin, including in New York, and assisted in creating shell companies to launder at least $400 million in proceeds, the DOJ alleged in March.

In 2017, the agency charged Ignatova with OneCoin-related fraud and money laundering offenses. She is believed to have fled to Greece and avoided the public since. She was added to the Federal Bureau of Investigation’s top 10 most wanted list in June 2022.

Greenwood pleaded guilty to one count of conspiracy to commit wire fraud, one count of wire fraud, and one count of conspiracy to commit money laundering in December. He was sentenced to 20 years in prison in September.
