No banks are too strong and also have too much power to let them disappear, I honestly think this will never happen.
Its just not possible, the banks will never let the bitcoin win.
Governments and banks will indeed never let Bitcoin come too close as that can harm their economy and way of doing business. It will never happen.
I prefer to just focus on what's important, and that's seeing the adoption of Bitcoin grow and that more average joe people will start with using Bitcoin. That's much more of importance to me.
It can only make it disappear if Bitcoin is really popular and that is not the case now because many people are still using their banks and that is the problem.
So we actually cant talk about it now, because Bitcoin is not that popular.
