Star witness at US crypto trial says Bankman-Fried ordered fraud

NEW YORK, United States — Disgraced crypto wunderkind Sam Bankman-Fried was the mastermind behind a scheme to defraud FTX clients of billions of dollars, the star witness in his US trial testified on Tuesday.

Caroline Ellison, Bankman-Fried's former business partner and girlfriend, said that they had stolen "around $14 billion" from clients of the cryptocurrency trading platform before it collapsed into bankruptcy late last year.

The 31-year-old Bankman-Fried, co-founder and former CEO of FTX, has been charged with seven counts of fraud, embezzlement and criminal conspiracy, and if convicted could face a de facto life sentence of more than 100 years in prison.

She has pleaded guilty to fraud charges and agreed to cooperate with the prosecution as have two other close associates of Bankman-Fried.

After taking a good 10 seconds to identify her former romantic partner in the courtroom, Ellison said he was "the owner of Alameda and he directed me to commit those crimes."

Bankman-Fried "was the one who set up the system" that saw Alameda take the client money from FTX and use it "for investments and to pay back debts," she said.

"For major decisions, I ran it by Sam. He was the person I officially reported to. He was the owner of Alameda. He could have fired me if he wanted to," she said.

A former analyst who developed mathematical models for market finance, Ellison said she expressed her reservations about the relationship between FTX and Alameda.

"I was somewhat concerned because it was something that customers weren't aware of and they wouldn't be happy if they'd learned about it," she said.

Bankman-Fried's lawyers are expected to argue against this depiction, saying that their client had little handle on the inner
