Put it differently, banks have failed to implement something more efficient and the “bitcoin” innovators have also failed on practical aspects. That, once again, is a very America centric view. A place where banks must be even worse than taxis. Within the Euro area (and associated coutries, like Switzerland), at least, SEPA transfers are quick and cheap, if not free. Edit to add: Even the developing world has fast and efficient money transfer schemes. Look up M-PESA, for example.
