For me, it is not possible that bitcoin can beat the banks. Yes, we all know that bitcoin helps a lot of us to transfer crypto/money easier, faster, and conveniently. With the used of bitcoin, you can transfer funds instantly without paying a huge amount. But to be honest, it will be difficult to beat the banks. Because banks are the platforms for physical currency such as FOREX (Foreign Exchange) and most of us using it. Banks also helps different country to buy, exchange, sell, etc. to the other country.
I totally agree with you! I think it is unlikely that the cryptocurrency will overtake the banks, but the banks can fully cooperate with the cryptocurrency and I am for it. It must be that something new in the banking industry. It would be great!
