Why do I need a bank if I have a crypto currency? What does the bank have to offer such that it can not do this crypto currency? Banks only create unnecessary problems. They are completely subordinate to the states. Crypto currency allows you to transfer unlimited amounts of money quickly and without regulation
While I agree with this you must understand that we are an exception, most people are not ready to stop using banking services just because something new and better has appeared, you need to understand that many people accept things just as they are, they do not think about new ways of doing things, so as long as what they are doing works for them they do not have any reason to try any change.
Crypto is just a currency and you need different places for different services. Banks provide us not only security for our deposits but also give us many services. No time to explain all services but there is big different in cryptocurrency and banks. There is no comparison between these two. Both have their own values and I never want the banks to crash.
