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 wasnt here at the last halfing and the price will need to be much higher so im not too sure what will happen.
Well if price won't rise at all then yes, miners will leave their jobs because they won't get any profit, so bitcoin would die unless new miners would start mining, but i don't think that price won't rise at all
If the miners leave then the difficulty for mining the coin will drop significantly and the remaining miners will profit more from this.
