if the bank cooperates with bitcoin it might make it more difficult for us to get bitcoin, because as far as I know there are many obstacles if we deal with the bank
Why? It's just another kind of currency that requires deep knowledge of blockchain and storage experience. If the bank has such experts and permission from the financial authorities, it may work then.
The implementation of Bitcoin in banks had so much of technical issues and problems are there that's why Bitcoin will be not implemented by banks till today but there are some government issues will also be late for that but in future maybe it can be changed by the government at banks.
