However, FTX itself filed for bankruptcy in the second week of November, after days of speculation about whether it was fully liquid. The questions were sparked by a CoinDesk report revealing that much of FTX sister company Alameda’s balance sheet was composed of an exchange token, FTT, issued by FTX, which later prompted Binance CEO Changpeng “CZ” Zhao to announce he would liquidate his company’s entire set of FTT holdings. FTX later suspended withdrawals.
