No why,banks can integrate bitcoin,i know from my spanish friends that thay can exchange btc in banks money machines,Spenish can withdraw his funds in almost all over the Spain three banks are offering that kind of service
Can you please name those banks?
It might be that you're mistakenly thinking exchanges are banks.
Just because they operate an atm that doesn't make them banks.
As far as I know there is no bank doing any kind of bitcoin to fiat conversion or transaction.
I think anything could happen, depending on market conditions, when there is no bank customer and everyone switched to the bitcoin and then bank will disappear soon.
Just let us know if banks disappear and their place is taken by bitcoin ... where will you go to take a loan?
People of then have the wrong impression that banks just process transactions and take deposits.
Surprise... there is more.
Bitcoin and banks can work together without one "killing" the other
