Former crypto tycoon Sam Bankman-Fried has been sentenced to 25 years in United States federal prison for stealing $8bn from customers of the now-bankrupt FTX cryptocurrency exchange he founded.

A jury found Bankman-Fried, 32, guilty on November 2 on seven fraud and conspiracy counts stemming from FTX’s 2022 collapse in what prosecutors have called one of the biggest financial frauds in US history.
