I think never happen, I don't think Bitcoin will make Banks disappear but it will create a separate space for itself. Too many world's finance operations are dependent on banks and therefore both of them will continue to co reside. So bank is never close
yes i am agree with you, bitcoin will never make banks disappear, but banks and bitcoin will work together and it will be good for both of them, if banks accept bitcoin then people will start using banks for bitcoin transaction and banks will get really good profit from these transaction.
It is a good idea, but banks should have to keep the fees for bitcoin transactions the same which other wallets have, they should have their own wallets for that with the name of their banks, it is be a better cooperation of these both, with that banks will also continue to get their profit and bitcoin will also get a more strength.
