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?
national currency for one country
bitcoin is Global currency every one have internet access can download wallet and start using bitcoin.
it is impossible for all countries to make 1 currency
It is impossible but some politicians all over the world are trying to do that, just look at the euro the currency for a full continent that is bound to fail, a closer political union made sense since the two world wars were devastating to the continent but then they tried to force economic union and as we have seen it is not going to work and this is going to dissolve the political union as well.
