FTX founder Sam Bankman-Fried will appear in court this week following the collapse of the crypto exchange and the alleged theft of billions of dollars. Key witnesses include former colleagues and friends, particularly Caroline Ellison and Gary Wang, who had close ties to FTX and Alameda Research. Allison, who was once romantically involved with Bankman-Fried, has insight into the inner workings of FTX and has admitted to deception. Other witnesses, such as Nishad Singh and Wang, held significant positions at FTX and Alameda and admitted to committing crimes.
