NEW YORK (AP) — Sam Bankman-Fried’s lawyer said Tuesday that a recommended sentence of 100 years in prison for the FTX founder by an arm of the court is “grotesque” and “barbaric” and a sentence of a few years behind bars is appropriate for the cryptocurrency crimes that the California man still disputes.

In presentence arguments filed just minutes before a late Tuesday deadline in Manhattan federal court, attorney Marc Mukasey said a report by Probation officers improperly calculated federal sentencing guidelines to recommend a sentence just 10 years short of the maximum potential 110-year sentence.

A spokesperson for prosecutors, who will respond in court papers in mid-March, declined comment.

On March 28, Judge Lewis A. Kaplan will sentence the man prosecutors say cheated investors and customers of at least $10 billion in businesses he controlled from 2017 through 2022.

His FTX trading platform was perceived by some in the cryptocurrency industry as a pioneer before it collapsed into bankruptcy in November 2022, weeks before he was brought to the United States from the Bahamas for trial.

At a November trial, the 31-year-old man known for his casual clothing and wild hair, was convicted of fraud and conspiracy charges.

Mukasey wrote Tuesday that the Probation office miscalculated federal sentencing guidelines to justify its recommendation. A proper sentence, Mukasey said, would be based on guidelines that would call for between five years and 6 1/2 years in prison.

When Bankman-Fried’s charitable works and his commitment to others are considered, an appropriate sentence would return him “promptly to a productive role in society,” the lawyer said.

Mukasey said that the Probation office “recommends that the Court sentence Sam to 100 years in prison. That recommendation is grotesque.”

“Sam is a 31-year-old, first-time, non-violent offender, who was joined in the conduct at issue by at least four other culpable individuals, in a matter where victims are poised to recover — were always poised to recover—a hundred cents on the dollar,” Mukasey said.

He called on the judge to reject the “barbaric proposal.”

FTX was once the world’s second-largest crypto exchange and Bankman-Fried seemed to be flying high with the purchase of Super Bowl advertising and endorsement from celebrities including comedian Larry David and NFL superstar quarterback Tom Brady.

After his arrest, though, Bankman-Fried’s communications were found by the judge to be attempts to influence trial witnesses and he was jailed before trial.
