The former head of legal and compliance at OneCoin was sentenced to four years in prison after pleading guilty to fraud charges regarding her role in a cryptocurrency marketing scheme.

Irina Dilkinska’s sentence, announced Wednesday, follows her guilty plea in November to one count of conspiracy to commit wire fraud and one count of conspiracy to commit money laundering. She faced a maximum of 10 years in prison.

Dilkinska was also ordered to forfeit more than $111 million.

Bulgaria-based OneCoin 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, according to the Department of Justice.

Victims invested more than $4 billion in the fraudulent cryptocurrency.

“Irina Dilkinska’s involvement in the sprawling OneCoin pyramid scheme was a flagrant breach of conduct,” said U.S. Attorney Damian Williams in the Southern District of New York’s press release. “Rather than upholding the law and embracing her position as the head of legal and compliance, she facilitated and committed money laundering, aiding in the exploitation of millions of victims.”

Dilkinska was also sentenced to one month of supervised release.
