On many occasions I think we have seen that banks publicly stating that they will not support crypto adoption will only make them worry about the emerging economic problems. Obviously they look scared, but going forward we really don't know how this rule can be softened.
Banks have personal reasons why adoption is impossible and one of them may be because of their desire to own a fully centralized cryptocurrency. The adoption of crypto, especially bitcoin, will only make them lose their income in the form of investing in customer funds that they have been using, people prefer bitcoin which is very easy to make transaction and many other things.
Of course, it cannot be denied that the emergence of a decentralized cryptocurrency and especially its successful further development and distribution around the world is a big problem for the banking system. In any case, cryptocurrencies have already taken a decent part of their profits from banks, as more and more people keep their money not in banks, but in cryptocurrencies, which in many cases provide significantly more profit than banks offer. At the same time, it cannot be said that the banks are strongly concerned about their continued existence. I believe that banks have nothing to fear in this regard, since the banking system as a whole is under the direct protection of states. In addition, banks perform other functions of servicing the financial and economic activities of institutions and organizations of all forms of ownership, as well as the economy of the state as a whole, which cryptocurrency cannot perform. Therefore, as long as states exist, their banking system will exist.
