Even then if they want to accept Bitcoin.
So, how if the world wouldn't accept Bitcoin? You should imagine that too
IMO the world for the next 10 or 20 years later will accept Bitcoin and i wouldn't imagine if Bitcoin not accepted by the world when someday we already have grand children
I have soft corner for bitcoin in the future, But I dont think It will remain alive after next 10 year because of the its anonymity. This currency may be used for feeding the terrorist of black money storage. It will be banned by the USA or other great power. But im hoping for the better future of bitcoin
