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.
That's true the public is looking for something that they are comfortable of using with, paper money is very easy to use and it's not complicated
like the online currency so let us not think that this world will be a digital currency world in the future.
