I think that before answering this question, you need to answer other questions, namely, what exactly does the banking system do and what is the advantage of using Bitcoin and what is its functionality not only in the cryptocurrency market, but also for society. To a large extent, today Bitcoin is used as a valuable asset, not only for investment, but also for storage. and the banking system provides lending, financing and other financial services. If the banking system adapts to the new realities, then at any time it will be able to provide services to cryptocurrency users for storing Bitcoin and other services, since there will be a lot of cryptocurrency users who will want to have cryptocurrency, but will not have enough knowledge and experience.
