And becomes a giant world currency...
Wouldnt there be quite the HUGE interest by govs of US, russia, china to own huge parts of it?
I do not see the need for certain countries to try to control the bitcoin, since they have been making considerable efforts to damage its reputation, but when they realize that its advance is unstoppable, it will be too late for those countries and there will be big capitals holding the majority of bitcoin.
But on the other hand, all these systematic attacks could also try to dump the price of bitcoin to subversively acquire its domain at better prices.
