FTX founder Sam Bankman-Fried has appealed his conviction and 25-year prison sentence for stealing billions of dollars from customers of his defunct cryptocurrency exchange. Bankman-Fried was convicted in November on seven counts of fraud and conspiracy in what US authorities described as one of the biggest financial frauds in US history. The 32-year-old former billionaire was the poster boy for cryptocurrency, gracing magazine covers and enjoying audiences with lawmakers, before the speculator collapse of FTX in 2022 amid a deluge of customer withdrawals. Bankman-Fried’s lawyer Marc Mukasey had announced his intention to appeal the verdict and sentence during his sentencing hearing on March 28.
