So as far as we know BTC currency is growing wide, do you think there will be when it become a national currency?If yes, why?If not, why?
I do not think so...
It is really hard to predict what will happen after next 15 years or so. But looking at the way Bitcoin has made its mark in the market, we can expect it to be a National Currency one day. But it will definitely take time.
It will only be possible if Bitcoin doesn't assume any central control at any point in time because becoming a national currency means the central bank or government of a particular nation has approved it and will they approve it as a legal tender without control? That's why it doesn't seem feasible to me even in the next 100 years.
Bitcoin is decentralized , it can have a central concern by a specific person. It can be used by anyone with no limits and kt xan consider as a national crypto maybe when its qpplicable to use physically ,which will took too long.
