The truth is that banks want money and they will certainly accept crypto because of the needs of their customers and of course the high profits to come
We are not entirely sure if any large Banking corporation will accept Bitcoin or not. So far it is not looking so well.
I am sure that many large banks will accept crypto because in crypto there is a sophisticated, fast and efficient blockchain that makes one feel comfortable. but whether it's when no one will know because it needs control and control so it is truly safe, there are still many governments that are not sure and afraid to use crypto.
