American entrepreneur and crypto king, Sam Bankman-Fried was sentenced Thursday to 25 years in prison for his role in defrauding users of the collapsed cryptocurrency exchange FTX.

In a federal courtroom in lower Manhattan, United States District Judge Lewis Kaplan called the defense argument misleading, logically flawed, and speculative.

Kaplan said Bankman-Fried had obstructed justice and tampered with witnesses in mounting his defense - something Kaplan said he weighed in his sentencing decision.

After a two-hour hearing the judge, Lewis Kaplan, said Bankman-Fried knew what he was doing was criminal and regretted making a bad bet about the likelihood of being caught.

Bankman-Fried, wearing a beige jailhouse jumpsuit, struck an apologetic tone, saying he had made a series of selfish decisions while leading FTX and threw it all away.

It haunts me every day, he said in a statement. There are a lot of mistakes that I made.

Bankman-Fried, however, told the court that FTX had the ability to repay customers when it collapsed.

Meanwhile, the prosecutors said Bankman-Fried took more than $10bn (£7.9bn) from unsuspecting customers in one of the biggest financial frauds in US history.

FTX was valued at $32bn before it went bankrupt in 2022 and SBF crafted a public image that drew in celebrities, politicians and business titans.

Prosecutors had sought as much as 50 years, while Bankman-Frieds legal team argued for no more than six and half years.

He was convicted on seven criminal counts in November and has been held at the Metropolitan Detention Center in Brooklyn since. (Vanguard)
