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.
This is true, they will never approved to the possibility thatz bitcoin may invade government and give what do people deserve. For now the implementation of Bitcoin to may be challenging, and cash will still exist for the entire century I guess, cause public and private entities who accept Bitcoin as payment were still limited for now.
