Do you mean the bank as a whole?
In my view, so far we are still not completely convinced that unless the country opens up its policies globally regarding the status of Bitcoin, then banks will be able to do the same. However, if you operate where Bitcoin is not used as a legal medium of exchange, the bank will face a very risky challenge. Transaction involvement in banks is about controlling financial entry and exit, so to see banks implementing the Bitcoin payment system means we need to look at central government policies first and not immediately establish policies outside the bank's authority.
