. I can't ignore bank if I want. Because I can't use my bitcoins to buy anything here. That's the real fact.
Indeed. There are really some countries who don't let us to use bitcoin as a legal currency, that is why we end up storing half of our profit in banks and the other half is in our crypto wallet. We still need banks because even we mostly use cryptocurrency in our transactions we still need fiat to buy our goods and necessities. . I can't ignore bank if I want. Because I can't use my bitcoins to buy anything here. That's the real fact.
