I am very sure that one day, traditional Bank will begin to accept Bitcoin as a legit medium of exchange, people need to be given freedom to deposit their BTC directly just like the regular money. I believe that this will come to pass when the major world powers officially recognizes and adopts Bitcoin, this will make a foundation for banks to stand up and integrate it into their financial system. I believe in Bitcoin .
Although decentralized financial systems are the opposite of centralized financial systems, it is not possible to merge these two financial systems. It is possible to harmonize the financial system by adopting many methods strategically. Central banks of various countries have formulated great strategies by introducing CBDC (Central Bank Digital Currency), a real form of digital assets. Some states in America have passed laws to strategically reserve Bitcoin and will introduce Bitcoin for future purchases and daily financial management in those states. But banks are managed by the centralized financial system. Although it is not entirely possible to integrate decentralized assets like Bitcoin with the centralized traditional financial system, it will be an important hedge for the global economy through the application of new strategies.
