I would very much like to see how it will be, because now these fiat money is already boring and as soon as they integrate crypto currencies, the price in fiat money will immediately divide, because only in the finacies can it be possible to carry out dark affairs.
Fiat won't get boring to Bankers. Bitcoin is not close to removing fiat, I am pretty sure that Bitcoin won't ever replace Fiat. Fiat will be there just under a different name.
