FTX founder Sam Bankman Freud’s attorney filed a notice of appeal Thursday against his federal fraud and conspiracy conviction and his 25-year prison sentence.

Bankman-Fried’s appeal comes two weeks after he was convicted in U.S. District Court in Manhattan and ordered to pay $11 billion in forfeitures for massive fraud at cryptocurrency exchange FTX and its related hedge fund, Alameda Research. given. Prosecutors said it was one of the biggest financial frauds in history.

The appeal, which was expected, will be heard by a three-judge panel of the 2nd Circuit US Court of Appeals, which sits in Manhattan.

Criminal defendants face very long odds of getting their convictions overturned in federal court, with fewer than 10% of appeals being reversed. If Bankman-Fried loses in the 2nd Circuit, she will have to petition the U.S. Supreme Court to take her appeal, which is even longer.

Alexandra Shapiro, the attorney who filed Bankman Fried’s notice of appeal, did not immediately respond to a request for comment Thursday.

Bankman-Fried, 32, was convicted in November of seven counts of fraud and conspiracy to misappropriate nearly $10 billion in consumer money.

The Manhattan U.S. attorney’s office said Bankman Freud oversaw a scheme that diverted consumer funds to invest and make political donations to Democrats and Republicans. He also used the fraudulent funds to pay off personal expenses and loans taken out by Alameda Research, prosecutors said.

As he sentenced Bankman Freud, Judge Lewis Kaplan said, “There is a risk that this man will be in a position to do very bad things in the future.”

“And that’s no small risk at all,” added Kaplan, who noted that he never heard Bankman Freud “say a word of remorse for the commission of the terrible crimes.”

Bankman-Fried, the son of Stanford law professors, has suggested that FTX lost billions of dollars in customer funds due to a “liquidity crisis” or “mismanagement.”

FTX and four other top Alameda executives previously pleaded guilty.

One of them, Ryan Salame, will be sentenced by Caplan on May 28.

Carolyn Ellison, who was the CEO of Alameda. Gary Wang, Head of FTX Technology; and Nishad Singh, who was the engineering boss of FTX.
