we are all ignorants about the reality here, so we are all guessing
but when you have to guess stuff about the crypto market, you literally have to think the worst things or the best things and you will be right
my guess here is simple, CZ has liquidated everything that can be liquidated that doesnt make him look bad, hes deep in the very same business than FTX/Sam was, he doesnt need to look the balance sheet, chances are his balance sheets are similar or worse haha
So he probally liquidated longs if any, he probally did OTCs with other tokens/assets and just kept the FTT as a PR move to pretend he was a nice guy, anyways having an amount of $ "lost" by a token that was never worth anything is still 0 lost, he most likely got those tokens in exchange for other tokens worth nothing, or during ICOs stage so pretty much hes not losing any cash even tho you will read people saying how much he lost, remember all of that is nominal value, not real cash value at the end, the very same reason things are falling now.
