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...
I don't think bitcoin can make the bank disappear. The reason is very simple that in the world there are many countries and not in any country where the technology flourishes as in the US and Japan ... so the bank is still the first choice of all. for their convenience. we can withdraw money on ATM stations are placed a lot of places. But if you move from the coin altcoins cashier then you take a lot of time. This is the reason why the bank is always strong.
