In Michael Lewis's book "Going Infinite," it is mentioned that Sam Bankman-Fried (SBF) was affiliated with FTX, a cryptocurrency exchange, and was the founder of a cryptocurrency trading and investment company called Alameda Research. According to the book, after launching Medari Research, SBF experienced significant daily losses amounting to $500,000. He had raised around $170 million from investors in the "effective altruism" community, and these funds were initially used for high-frequency trading, resulting in substantial revenue in the first month. However, the trading strategy suffered losses, and there were issues with fund management until Gary Wang and Nishad Singh joined the team. It is noted that the situation improved after their arrival.
