The first part is nonse however, because govs can really simply ban bitcoin by banning all the bussiness that accept it.. if no normal bussines (grocery, electronic, housing, energy, transport etc. etc. etc.) accept it, the price CRASHES= bitcoin is dead. (using it only in the black market wont save it). Decentralization is worthless argument here.
And if this happens how do you think people will react?
This is not a game for nerds anymore, there are serious money invested, serious businesses in the industry and global visibility thanks to internet.
sorry but no, people wouldnt care... omg people get real, do you think that the majority of people would "riot" due to some crypto currency (ban)... you cant be serious, a lot of people arent even sure what inflation is, and you expect that they would "fight back" againts gov. ban on bitcoin... really... sorry but thats naive.
