From what I have seen so far in this forum and other crypto platforms, most of us want fiat eliminated. But let us not forget that there are still situations whereby we can't use crypto except fiat like in rural places without computers or even internet facilities.
I think it is very difficult to completely eliminate fiat because many people are used to it and it has been very long. We should have thought that crypto would make it easier for people to trade, rather than forcing it to become an official currency, which would make you feel more positive at the beginning. invest in crypto or wait for their prices to rise
