Not just ftx, the market in general seems to have a lot of fraud and as of now it seems like it's too easy to magically make money appear(hyperbole).there's also that most stable coins that I know of are backed based on usd or some other currency, which is a problem when talking about cryptocurrency becoming the new global currency.

I also personally dislike the technology and the people leading the charge, I don't think privatized currency would be a good thing for most people, so in my view a govvy run cryptocurrency just seems like worse money.

Feel free to tell me why I'm wrong though, I've done enough research to form opinions but not enough to be sure about them
