If the price doesnt rise then the miners stop mining because of lack of profit, Once this happens the network becomes less secure and bitcoin starts dying off. Whats to stop this from happening? Maybe we are getting to prices that cant be maintained with the current user base. I wasn't here at the last halfing and the price will need to be much higher so im not too sure what will happen.
i am sure that price will rise, and miners will be happy about that so everything will be okay, would be dumb to think that price won't rise at all, when so many people buys bitcoins now
but if something will happen and price won't rise, then miners will have to leave their jobs as they won't get any profit from mining anymore, so that would be very bad for bitcoin
