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.
