Former Alameda Research CEO Caroline Ellison has been sentenced to two years in prison for defrauding investors of crypto exchange FTX and its sister firm.
Judge Lewis Kaplan of the U.S. District Court of the Southern District of New York handed down the sentence, citing Ellison's strong cooperation as a witness against former FTX fraud ringleader Sam Bankman-Fried last fall.
“I’ve seen a lot of cooperators in 30 years," said Kaplan, per Bloomberg. I’ve never seen one quite like Ms. Ellison.”
Ellison must also forfeit $11 billion, Kaplan said—the same amount demanded of Bankman-Fried.
