A cofounder of the OneCoin pyramid scheme pleaded guilty to his role in the global, multibillion-dollar fraud.
Karl Sebastian Greenwood admitted OneCoin, which he founded in 2014 with Ruja Ignatova, the so-called “Cryptoqueen,” was based on a phony cryptocurrency. Greenwood, who was arrested in Thailand in 2018 and extradited to the US, pleaded guilty Friday to three criminal counts of conspiracy and wire fraud in a hearing in Manhattan federal court.
