No I do not think this is possible if I'm very honest because the bitcoin is just to small right now maybe its possible in the future.
But the time will learn it because the bitcoin is not to predict of course.
I agree, and it is never easy to make banks disappear, in future bitcoin will be used more but there are certain percentage of people who would prefer to use banks and not bitcoins.
It will be not possible of course. Many people will use it and there are also many people that dont even know what Bitcoin is.
And that is the problem. You must make first Bitcoin more popular and than you can talk about the banks will disappear.
There is a possibility of course that it can happen. If Bitcoin will be very popular in the future than why not.
Of course it will reduce the banks in the future because Bitcoin is more used so that is quite good.
