If indeed FTX goes bankrupt, it will be a big disaster for the crypto world and you can be sure that the FTX token will no longer be valuable, because it is no longer used. Hopefully there is still a way to save it
I think the exchange will still exist but with another ownership. There will be a long procedure to take over FTX exchange after the bankruptcy. FTX token will be fine in aspect that it won't die and disappear.
I don't know what is the price of FTT token in its ICO, lowest price. Maybe we have to prepare for the bad when the token will fall to ICO price. I still positively think that the token won't be divided hundreds or thousands of times like Terra $LUNC.
At least Sam did more quickly response than Do Kwon and it reduces panic. More than that, there is no billions of FTT token minted from the air like LUNC token.
FTX just filed for bankruptcy, and they are not really bankrupt yet, the chance for FTX is still but very low. If someone agrees to buy back FTX, it means they have to pay off FTX's debt to be able to use FTX, otherwise it's gone forever. FTT is the native token of FTX, it will not exist if FTX is no more, no exchange accepts a useless token for circulation.
