Bitcoin will not eliminate banks, because the function of Bitcoin itself is to serve as an alternative to the current banking system. Additionally, banks still play an important role in society, such as providing a place for savings, handling local transactions, offering financing, and more. This means there are still many features of banking that cannot be fully replaced by Bitcoin. Governments also do not appear to support the idea of Bitcoin replacing the role of banks, which is why the use of Bitcoin remains limited and is not recognized as a fully legal means of payment in most countries.
Yes, it is true that Bitcoin is not recognized as a means of payment in most countries. However, Bitcoin should not be compared to banks, but to a fitter, I think it can be used as an alternative. Although banks currently play an important role, they have some features that cannot be completely replaced by Bitcoin.
