If bitcoin will have a stable or lets say " fixed price" then it could be sign that bitcoin is our next currency.
But bitcoin must be known all over the world first.
Bitcoin is know, but it's time for people to use it, alas webshops start accepting this great coin us customers being able to use it.
A stable price will not come for at least a few years.
Stability is the reason people would buy bitcoin or even accept it, These days it is too risky to buy bitcoins or accept it, because as a merchant you want to have a fixed value for your product.
