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.
It will not happened even for a decade. Don't worry.
Most people here just expecting too much
without looking at the reality and the massive effect of it.
Crypto will grow more but fiat will still be there.
This will take a long discussion so I will leave a simple statement first.
