The account of Sam Bankman-Fried, ex-CEO of bankrupt crypto exchange FTX, who's serving a 25-year jail sentence after his multi-billion-dollar scam came to light, has posted on X. "gm," the post made at about 5:00 am said. Over three hours later, his account posted again, clarifying that it wasn't Bankman-Fried posting from prison but a friend posting on his behalf.
