In an interview on Monday, Axios asked Sam Bankman-Fried—who was once said to be worth $26.5 billion—about his personal finances. His response: “Am I allowed to say a negative number?” "I mean, I have no idea," Bankman-Fried said. “I don't know. I had $100,000 in my bank account last I checked.” He said determining his wealth was "complicated," and that basically everything he had was "tied up in the company," which was valued at $32 billion before its collapse. Of course, earlier this month FTX filed for Chapter 11 bankruptcy. The company suffered a liquidity crisis due to a customer exodus, leading to its collapse in just 48 hours and allegations of fraud. “I wish I'd been more careful,” Bankman-Fried told Axios. “I obviously deeply regret this. I've been focusing on volume, rather than positions for balances. I should have been more responsible, and I should have been more on top of what was going on.” He said he thinks regulation could have helped prevent FTX from imploding. "There's certainly an extent to which that I wish there had been someone who wasn't me who was in charge of managing conflicts of interest," he said, adding, "I wish that I had more reporting and transparency to outside parties." The implosion has shifted the image of Bankman-Fried, who often went by SBF, from a crypto hero and the next Warren Buffett to a cautionary tale who's lost billions of his personal wealth and at least $1 billion of customers' funds, Reuters previously reported .
