Bank want to use as a share but it will not possible in the future. They will take government power and push people to hold btc to their system which is not good sign also.
I think bank will not think that they will use bitcoin for people because it is totally decentralization and people want also decentralize wealth and money which available in btc.
Launching a Crypto Bank is not as easy as we are talking about, you have to overcome many challenges and obstacles, because there are still many of us who don't know what Crypto is, and how it works, how to use it, there are still many question marks from all levels of society, especially for people ordinary people, they don't know how to use it and how to use it, because what they know is that every purchase uses fiat currency, so we have to go through a long period of socialization, and even then not everyone can accept the ideas we give, there are many things we have to think about In my opinion, this is all a bit difficult to develop, it will just be a discourse.
