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.
Well I'll tell you something why banks hate bitcoin, which has nearly been told over and over again in this thread. Bitcoin offers transparency in which everyone can see all the transactions done from who, to who, by who.
That is one thing that banks will not offer, which is why they wouldn't want a bitcoin bank. Unless they have a way to hide it, but it seems to be impossible.
