no i said bitcoin will not become the hero for US to replacing Dollar,lets see how new yuan start to developing in china,its need good trust from civilian,they all agree and pleasure to use yuan and say no to dollar,but US can't do that to bitcoin.
for the US there can be only one hero, himself, so i doubt so much than this will happen too.
btw replace any currency is an aggressive option, maybe this will happen anytime, but my vote is to start to coexist progressively (like now, step by step..)
If the dollar goes down the toilet so do all the other currencies pegged to it.
yes, even if we like it or not, US have an high impact on what they do especially on europe.
