I'm not convinced that the issues that caused Binance to back out even existed the last time FTX raised outside capital (March 2022 according to Crunchbase). My understanding is that in March, FTX had a basically normal balance sheet for a crypto exchange, with roughly enough non-FTT assets to balance against its liabilities.
Alameda was an over-leveraged crypto hedge fund, which in hindsight wasn't great news for Alameda's investors or creditors. But there's a world where Alameda goes to zero but FTX is mostly fine. After all, FTX would automatically recalculate margin levels and liquidate assets as needed every 30 seconds. If they did that with Alameda like they would have for an arms length counterparty....I'm not going to say that FTX would have been unscathed - a lot of those loans seem to have been secured by FTT, plus Alameda seems to have made up a lot of FTX's trading volume - but the end result of incinerating billions of dollars' worth of customer deposits wasn't inevitable. IMO, FTX's fate wasn't sealed until its management team built a backdoor into its systems to siphon customers' assets to Alameda. And that probably didn't happen til summer, months after its last funding round.
