Sam Bankman-Fried has been found guilty of defrauding customers of his cryptocurrency exchange out of billions of dollars.
The 31-year-old man could be sentenced to more than 100 years in prison after stealing money from clients of ftx.
A Manhattan jury convicted him on all seven counts after a month-long trial.
FTX collapsed last November, shocking financial markets and wiping out the cryptocurrency tycoon's estimated $26bn (ยฃ21bn) fortune.
He was arrested in the bahamas in December and extradited to the United States.

Prosecutors claimed he used the funds for risky bets at his Alameda Research hedge fund, with a gaping financial black hole emerging when crypto markets fell sharply.

Bankman-Fried's fall from grace has seen him compared to well-known financial fraudsters Bernie Madoff and the "Wolf of Wall Street" Jordan Belfort.

"He thought the rules didn't apply to him. He thought he could get away with it."
Former Alameda CEO Caroline Ellison and former FTX executives Gary Wang and Nishad Singh pleaded guilty and testified against Bankman-Fried last month.
They said he told them to help Alameda loot funds from FTX and lie to lenders and investors.
The defense claimed that the trio had falsely implicated him to obtain a lighter sentence, but after his testimony, Bankman-Fried took the calculated risk to give evidence.
He admitted to making a mistake by not having a dedicated risk management team, but stated that he thought Alameda's loan to FTX was permissible.
He told the jury he did not realize how large the debts had become until just before both companies collapsed.
