it's impossible because until now many countries not accept bitcoin and some of them are totally banned bitcoin. for countries with economic conditions is not good, they have worries if bitcoin can worsen their economic situation, I think it's difficult if bitcoin can accept in all country in the world
I don't agree totally with mate that it is impossible that world will start accepting bitcoin. Nothing is impossible. But that happening will take huge time because anything in legalization in any country have some SOP which should be completed while also bitcoin is still new in market as compare to fiat currency. So once it can get all qualities which will complete SOP's of all the world then surely world will start accepting bitcoin as a legal currency.
