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.
We get the point and I also think that it is not effective if we are going to totally eliminate fiat. We should just hope that fiat and crypto would work in harmony and surely we will all benefit on that. It is not just about being uncivilized on why we should never eliminate fiat but also with that fact that it existed first before crypto. All of us are using it right now and we will all still be using it up until the future. Banks regulate fiat so if we will always convince them to remove fiat, we would never have the chance of having crypto regulated in the banks.
