It has real value for as long as there are people who need a currency that isn't controlled by a government. In other words, it's an investment in the working capital of the criminal underworld. (and tinfoil-hatters) The money you put in is probably used to commit crimes of some sort, and the money you take out was probably the result of some crime. But with coins like Bitcoin that have a distributed trust in all miners to maintain the algorithm, I don't think you can say it's a scam. The ones I think are truly scams are the "stablecoins" and "exchange tokens", which are nothing more than a fiat currency offered by an entity smaller than a government with less accountability than a government, and no way to ensure the value/supply/demand of their coin. So yes, I think FTX was a scam to the extent that they traded FTT while printing or consuming it however they liked.
