Too much is still unknown about the alleged fraud of Sam Bankman-Fried to fully comprehend John Ray’s suggestion this week that FTX U.S. might be worth restarting. Ray, who took over as C.E.O. of the cryptocurrency exchange in November to manage its bankruptcy, is progressing rapidly with the forensic work required to clean up the mess, but the extent of the interconnected web of deceit and duplicity is still a mystery. There’s little question, of course, that S.B.F. controlled everything: Alameda Research, FTX International and FTX U.S., as well as the myriad of other companies he created to confuse and to obfuscate. What is still not known is how all these companies fit together and how the money flowed between them. Is FTX U.S. actually solvent, as S.B.F. is fond of asserting? And even if it is, did it remain solvent at the expense of FTX International and Alameda? And if so, why?
