This is not going to be visible in my view. Banks are under the regulation of government which is genesis of what to look at because it is when government include cryptocurrency as part of her financial dealings then the banks will be ordered to make such policy and provisions but where the government is not giving any of such window, her subject ( the bank) would not act otherwise. Apart from that and perhaps one of the reasons that the government is not making such policy is the issue of control and volatility. This part of volatility is the challenge of the volatile nature of cryptocurrency and it will be difficult to be peg in a particular price.
