Sam Bankman-Fried, former CEO of FTX, has been sentenced to 25 years for embezzling $8 billion in customer funds.

The conviction relied on testimony from three insiders, including chief software engineer Gary Wang.

Evidence from Wang's laptop showed deliberate manipulation of FTX software.

Bankman-Fried expressed remorse and intends to appeal, questioning the trial's testimony and his defense's restrictions.

John Ray III, FTX's current CEO, contends the company's recovery began only after Bankman-Fried's departure.
