OneCoin co-founder Carl Greenwood confessed to defrauding investors of $4 billion.
He co-founded it along with "cryptocurrency queen" Rouge Ignatovna, who is still on the federal wanted list. Greenwood, a Swiss and British citizen, was detained in Thailand and extradited to the United States. He will be sentenced on April 5, 2023. But the "cryptocurrency queen" was one of the ten criminals the FBI had a big problem with tracking down.
