im sure it can...but it will take a long time to make bank dissapear...
but make sure that all people know what is btc...in my country just a less people know bitcoin...
the same thing happens in my country too, bitcoin prices are high but the users are still few because still not many know about bitcoin, in because there is still prohibition against payment using bitcoin
If there are prohibitions then you cannot expect the users to grow, in fact this will decrease because what they are doing is against the law.
That is some of the scenarios that I am afraid to happen in major countries where bitcoin is so popular as for sure it will affect the price and will give bad impression to new comers, I hope the government are open for change and they will embrace this kind of chances that would benefit the people.
