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.
in this situation we are using the cryptocurrency as a part of our life but without the normal currency we can do anything in our life so this the difference between them so we cannot easily eliminate in any situation without the help of Normal currencies.
