Business partners turn on Sam Bankman-Fried
(CNN) -- The stunning collapse of one of crypto's most prominent firms has quickly morphed into a legal battle pitting former executives and ex-romantic partners against one another.
Last week, as FTX founder Sam Bankman-Fried was being extradited to the United States from the Bahamas, two of his former business partners pleaded guilty to multiple charges of fraud and conspiracy.
Caroline Ellison, the 28-year-old former CEO of the crypto hedge fund Alameda, apologized before a federal judge in New York, saying that she and her former associates knowingly stole billions of dollars from customers of Bankman-Fried's FTX exchange and sought to cover it up, according to multiple news reports citing court transcripts.
"I am truly sorry for what I did," Ellison told the court. "I knew that it was wrong."
Ellison has been charged with seven criminal counts, including conspiracy to commit wire fraud and money laundering. She and Bankman-Fried were close business associates who briefly dated.
Another associate, Gary Wang, FTX's former chief technology officer, pleaded guilty to four counts of similar charges.
Home for the holidays
Both Ellison and Wang are cooperating with federal prosecutors, making them potentially damning witnesses against Bankman-Fried, who has repeatedly denied intentionally defrauding customers and investors.
Bankman-Fried, 30, appeared Thursday in a US courtroom in New York, where a federal judge released him on a $250 million bond. He is required to surrender his passport and remain under house arrest at his parents' home in Palo Alto, California.
Although $250 million is an extraordinary sum, Bankman-Fried won't have to pay it unless he violates the terms of his bail agreement or fails to show up to court. The atypical bail plan was agreed to as part of his commitment to waive his extradition fight.
Following his court appearance, Bankman-Fried was spotted in a business class lounge at New York's John F. Kennedy International Airport. Crypto reporter Tiffany Fong also tweeted a photo showing Bankman-Fried on American Airlines flight.
Bankman-Fried's legal team confirmed to CNN Business that he had arrived in Palo Alto and was home with his parents. His lawyer declined to comment on the guilty pleas by Ellison and Wang.
The federal judge Thursday said Bankman-Fried would be arraigned on eight criminal counts including fraud and conspiracy at an unspecified future date.
Prosecutors allege that Bankman-Fried orchestrated "one of the biggest financial frauds in American history," stealing billions of dollars from FTX customers to cover losses at Alameda and to enrich himself. If convicted, he could face life in prison.
Bankman-Fried, prior to his arrest in the Bahamas earlier this month, had sought to portray himself as a hapless entrepreneur who got out over his skis. He repeatedly apologized to customers and to FTX staff, saying he "f---ed up," while denying that he knowingly defrauded anyone.
