To answer your question, banks will be obsolete. As every individual is in control of their own economy there is no need for banks.
This is a common misconception but it drives me crazy. There will be no need for
central banks, but banks will still be needed for credit services and the various other services that private banks are providing today.
The more banks will print money, the less powerfull they will be facing bitcoin. For the first time in the history of banking, banks cannot solve one of their problem (which is bitcoin) simply by throwing money at it. It will just get worst for them. They will have to adapt or die.
