Co-founder of OneCoin Pyramid Scheme Pleads Guilty, ‘CryptoQueen’ Still Wanted
One of the founders behind OneCoin pleaded guilty to federal U.S. charges on Friday after one of the largest financial scams of all time, according to the Department of Justice. The purported cryptocurrency project was fraudulent from its 2014 beginnings, prosecutors said, with OneCoin – co-founded by Karl Greenwood – setting up a pyramid scheme to market it to millions of people, generating as much as $4 billion in revenue.
