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.
Yes, it will take several time or years before fiat to be elliminated considering other people who don't know yet about crypto because they don't have access of it no internets and no gadgets. Don't worry my friend.
