That's like doing the opposite of what Bitcoin stands for in the first place. We say no to custodial storage and now you think Bitcoin will one day be accepted by banks, I don't even like the idea because they will have excuses to use that to attack Bitcoin when they have problems. The way Bitcoin is right now is how we want it or even better adoption. There is nothing better that banks will do with Bitcoin, I have a feeling that they are going to be worst than banks.

Instead banks accepting Bitcoin, I will rather see centralized exchanges start having offices in places where people can visit and see if there exchange is even real. This wouldn't help Bitcoin in any way but it will be fair to see them be that adoption. What we are expected of banks is to allow people use fiat to buy and sell Bitcoin as they want instead of this centralized dictatorship they are doing with customers money most especially in countries where there is no freedom for people.
