Yeah and even if bitcoin touches that price people will still prefer to sell them and convert to fiat so I don't think that fiat is going anywhere and the first choice of people will always be fiat.
Yes and if ever bitcoin will reached that price, it will just make fiat much worth. Since people care for the bitcoin price, they are happy for that kind of achievement of bitcoin and eventually they will sold their coins to take profit.
What is the sense of having a high price value for bitcoin if fiat will be worthless.
