I think that after all the regulatory bills are passed, then everything will be possible. But I also think that there will be no point in this, because the interest on the deposit will be so low that it will be pointless. In addition, this will mean that your coins are not with you but under the control of the bank, which contradicts the philosophy of Bitcoin and completely goes under the control of banks. I do not think that this is good and that it is worth doing, I would rather control my Bitcoin myself and know that no one can block my coins or do anything else with them without my consent.
To answer the OP question, it's very important to first understand what Bitcoin is and how it differs from fiat currency used in banking system or how banking system works. The core concept of Banking system is to control and manipulate the financial system of any country while Bitcoin differs from it as it gives the financial control in the hand of owner. I have said that so many times that Banks have no objection in accepting centralised Bitcoin which they can control, their rivalry is with decentralised Bitcoin which they can't control or manipulate.
This is true. Both have different systems and concepts, and how can they possibly be combined? This is difficult. Even banking is rife with manipulation, while Bitcoin represents freedom because no one can control it, and it's impossible for banks to control Bitcoin.
Bitcoin will remain under the control of its respective owners. Although countries are beginning to realize the benefits of Bitcoin, which is leading countries around the world to want to adopt Bitcoin, that doesn't make Bitcoin controllable. Therefore, Bitcoin and banking are difficult to reconcile because they are vastly different and go hand in hand.
