Former cryptocurrency executive Caroline Ellison has been sentenced on to two years in prison for her role in her former boyfriend Sam Bankman-Fried's theft of $US8 billion in customer funds from the now-bankrupt FTX exchange he founded.

US District Judge Lewis Kaplan said at a sentencing hearing in Manhattan federal court that he was not comfortable with remorse and co-operation being a "get out of jail free card" in a case so serious. Prosecutors have called Bankman-Fried's actions one of the biggest financial frauds in US history.

Ellison, 29, pleaded guilty to seven felony counts of fraud and conspiracy and testified as a prosecution witness in the trial of Bankman-Fried, who was convicted of fraud and other charges last year and is serving a 25-year prison sentence arising from FTX's 2022 collapse.

The crimes to which she pleaded guilty carried a maximum sentence of 110 years in prison. Her lawyers had argued for no prison time due to her cooperation. Prosecutors sought leniency as well.

Kaplan told Ellison she was "gravely culpable in this fraud," though he said her "remarkable co-operation" represented a "fundamental distinction" between her and Bankman-Fried.

"There's no way you're ever going to do something like this again, I am persuaded," the judge told Ellison. "But here's the thing: this was, if not the very greatest financial fraud ever perpetrated in this country or anywhere else, close to it."

Ellison crossed her hands on her lap and looked down at the defence table after the sentence was read. She earlier addressed Kaplan, speaking at a rapid pace and reading from a prepared statement.

"Not a day goes by when I don't think about all the people I hurt," said Ellison, a Stanford University graduate whose parents and two sisters were present in court. 

"My brain can't even truly comprehend the scale of the harms I've caused. That doesn't mean I don't try."

Ellison from 2021-2022 ran Alameda Research, a cryptocurrency-focused hedge fund Bankman-Fried founded. Ellison said she thought about leaving Alameda many times.

"Every time I thought about it, I heard Sam's voice in my head," Ellison told the judge. "Ignoring that voice in my head and speaking out would have been brave," she said, beginning to choke up and sniffle. "I'm sorry I wasn't brave."

Prosecutors said Ellison met with them about 20 times to help them piece together FTX's unraveling and make their case against Bankman-Fried.

"Unlike Bankman-Fried, she is not cunning. There is no evidence she was driven by greed, or that an appetite for risk or power was part of her nature," Sassoon said.

Kaplan said he would recommend that Ellison be incarcerated in a minimum-security prison and begin serving her sentence in November. Ellison may be eligible for release a few months shy of two years if given credit for good behaviour in prison.

Bankman-Fried, 32, rode a boom in cryptocurrency prices during the COVID pandemic to a net worth of, according to Forbes magazine, $US26 billion by October 2021.

His wealth evaporated when FTX collapsed in November 2022 amid a flurry of customer withdrawals. Bankman-Fried was charged a month later with stealing FTX customer funds to plug losses at Alameda. Ellison pleaded guilty in December 2022.

Ellison testified over three days at Bankman-Fried's trial, saying he directed her and others to take money from FTX's customers without their knowledge. Bankman-Fried is appealing his conviction and sentence.
