governments simply aren't interested in incorporating bitcoin. they can't deal with the fact that it is something they can't control. paper money will stay at least for another 10-20 years.
Well its not that they are not interested but well we can say that for now they are not aware what is the legit purpose of the existence of Bitcoin, I think they dont have the idea yet on how a country can be a better one with the help of acwuiring bitcoin in the society. The paper money will still remain, several testimony says that cashless society will never be a good thing to public.
