More business accepting bitcoin is the answer. As more and more people start to use bitcoin so the need grows with that comes price rises. Supply and demand.
But very honestly i would like to say, that currently i do not think that enough business have adopted bitcoin. may be in some places we can expect, specially in modern countries, but i do not think that there number are much more. But in future we can expect that a time will come when bitcoin will be use as currency and then most of the businesses will accept bitcoin for payment methods.
Although it is not much but nowadays it is growing. I do not know who but I saw many bosses and some industries are adopting bitcoin right now and it is really good for us when the price ia reall huge. But we never know if this is going to be bubble or it has strong fondation. We can't really predict what is the outcome when we can't control it
