Among its other endeavors, FTX created FTT, a token that had a peak notional market cap just under $10B, and that value seems to have been used to paper over massive holes in the FTX balance sheet. Massive, unexplained movements of FTT between FTX and Alameda Research[1] presaged the imminent collapse of both companies, and Binance dumping their FTT holdings was the precipitating event. FTX is about as "crypto" as you can get.
