Do Kwon, the South Korean cryptocurrency entrepreneur behind two digital currencies that lost an estimated $40 billion in 2022, was sentenced on Thursday to 15 years in prison for what a judge called an ¡°epic fraud.¡±

U.S. District Judge Paul A. Engelmayer, who handed down the sentence, sharply rebuked Kwon for repeatedly lying to everyday investors who trusted him with their life savings.

¡°This was a fraud on an epic, generational scale. In the history of federal prosecutions, there are few frauds that have caused as much harm as you have, Mr. Kwon,¡± Engelmayer said during a hearing in Manhattan federal court.
