I believe that all stable coins are easier to trample on by the government, more than other crypto projects in this space, Fiat has it's usefulness, let's stop deceiving ourselves, the first time I ever purchased Bitcoin I use Fiat and I believe this is the same as everybody on here, unless you mine your own Bitcoin or get paid in Bitcoin working online.
Do not trash Fiat yourself when it's actually needy, crypto and Fiat must co-exists until the government decide to go digital with Fiat themselves, and Fiat is not trash.
Fiat does have a much greater use in the journey of human life and even when we want to buy bitcoin we actually need fiat. Nobody says fiat is rubbish because it has so many uses in such a wide scope. The exception is if someone mines or works for a fee using bitcoin, so fiat is not really necessary, but if we talk in general, we can conclude that fiat is still a necessity for humans today.
I have often said in the past that bitcoin and fiat can live side by side and do not need to be competitors with each other. As long as government regulations make it clear that legal means of payment still use fiat, fiat will forever be a necessity for humans. The correlation of fiat as rubbish is not entirely true and we still need it today as a general transaction tool.
