no, i don't think so, but i think it will "accompany" USD more like now, and it will become more and more popular
Well, although bitcoin very special on the internet, but I also do not believe that bitcoin could replace one of the world's currencies, especially the dollar. Well, bitcoin can be compared with gold, but with the dollar. it is because bitcoin has a very high price. so, I feel that bitcoin only be a viable alternative.
yes it is infact a digital alternative to fiat currency.Bitcoin will not replace any currencies in the world and it is not meant to replace anything.But the valuation is the most important thing and with the current price we cannot even compare the two.
