Now we can see some countries are regulating bitcoin and some government don't like it.Otherwise Bitcoin hasn't a stable price.
So my question is can bitcoin be a main currency of world economy?
Is it really possible but then it takes a lot of time and effort if it happens. It takes time because it should be introduced to the peopl who are not civilized or those who are in rural place. It takes effort because there are lot of changes, rules and regulations to be implemented if it happens. But then who knows.
