Banks will never support the crypto currency trades and neither they are approaching that way toward them. The wire transfer is completely different thing and that gets separated with the membrane of decentralisation and centralisation. In this one crypto exchanger being decentralised can get the money transferred from one country to another as they dont recognise the location and neither they restricted to do so. But when it comes to the wire transfer from one country to exchanger of another country then are restricted to do so due to the rules and regulations of transferring bank itself. There is no doubt that this can be solved as long as both the parties agree on the rules. This cant happen as exchangers are devoid of the rules.
