I think very great and helpful if banks will realize the importance of cryptocurrency and perhaps enter into crypto. They can provide their usual services to customers and also provide services in cryptocurrencies, such as investment, savings and loans, shares buying with crypto, and a lot.
The people managing the banks are really smart, they understand very well what it is at stake here, they know that if they accept bitcoin that will be a sign of weakness, that they have basically capitulated and accepted the fact they cannot defeat bitcoin so believe me they are not going to do that until they are forced by bitcoin to comply with it.
