Personally, I see the future without fiat money, but a full cashless settlement. The Internet currency is the currency of the future, there will be a word behind it.
That is impossible to happen. though we already have different crypto currencies around and they are more known, fiat will never be removed from countries. We need it, and what are you saying is not necessary in this topic because what you said falls into another problem. It only says here thay bitcoin will be dominant over fiat because of what it can do in transactions.
