You are from which countries? It's still pretty hard, long and costly to transfer cash from a bank to another one. In fact at mine, still until recently it took 24 hours just to add someone to send him fund from the same bank. Interac, which is the provider of debit in Canada, recently made a way to transfer cash that many banks decided to add for a cost of 1$ per transaction. It's now widely used and banks use that as an incentive now (2 free transactions a month, amazing!). This is all due to old antiquated technologies used by the banks. They clearly don't want to evolve. Bitcoin at least is universal, simple and works.
