It is unknown what competition between banks and cryptocurrencies will be after the widespread introduction of CBDC. It is unlikely that we will see the closure of banks in the next few years. Most likely, centralized finance and decentralized finance will develop and exist in parallel. Even if there is a direct threat to the banking system, governments are more likely to start restrictions for cryptocurrency than to destroy banking institutions. This is not beneficial to big capitals, and of course, no one will give full power to decentralized finance, where there is no state control. Therefore, replacing banks with DeFi is more of a fantasy.
