Sam Bankman-Fried co-founded the FTX crypto exchange in 2019 and quickly built it into the world's second most popular place to trade digital currency. Prosecutors soon charged Bankman-Fried with misappropriating billions of dollars in FTX customer deposits. FTX had two lines of business: a brokerage where customers could deposit, buy, and sell cryptocurrency assets on the FTX platform, and an affiliated hedge fund known as Alameda Research, which took speculative positions in cryptocurrency investments.
