FTX founder Sam Bankman-Fried, sentenced to 25 years in prison last month for orchestrating one of the largest financial frauds in U.S. history, filed an appeal in federal court Thursday.  

The 32-year-old former mogul was sentenced in March, four months after a New York jury found him guilty of two counts of fraud and five counts of conspiracy that led to the seismic collapse of his cryptocurrency exchange and affiliated hedge fund.
