30-year-old crypto billionaire Sam Bankman-Fried reveals how he made his billions

Five years ago Sam Bankman-Fried hadn't bought his first bitcoin, but today, he's one of the youngest billionaires in the world thanks to the cryptocurrency, and one of the most powerful people in the young but fast-growing crypto industry. Bankman-Fried, who has been touted by some as the next Warren Buffett, still drives his Toyota Corolla, and he tells CNBC that he plans to give 99% of his fortune away to charity. CNBC's Kate Rooney travels to FTX headquarters in the Bahamas for an in-depth interview with the man some call "Crypto's White Knight."
