LOl it is not that banks hate bitcoins why would they hate them they dont even need to work with bitcoins the only reason thy men think they would hate bitcoins is that bticoin has a gold value and banks owns that gold.
But I do not think that banks not hate bitcoin for the reason of gold like concept of bitcoin. Gold will also increase their annual income and everything so, if they accept bitcoin also will do the same.
I believe in future banks will be offering a service that you can buy bitcoin from them, like what they are currently doing with gold.
