We all should not be surprised about the increase in the price of FTX because many things might have been going underground so that to attract customers again to believe in the system and purchase there token which might increase the market cap making extra funds to pay customers. Many investors and traders had lost hope in FTX for long now because of the previous bankruptcy of the company. If you are convinced enough for buy and hold there token then go ahead but I would never allow or advise people to buy such a token. There reputation is based now with several court cases against the company.
