Bitcoin isn't better for remittance. Actually moving the money has never been the expensive parts of remittance it is giving people a way to receive money on the other side and compliance. The current bitcoin remittance companies advertising lower fees are doing it entirely by ignoring compliance and that will work great until they have any volume and then they will be shut down.
I've heard people say "BTMs save money on not needing a store" but do you think if an automated machine was doable WU wouldn't have replaced most of their partner branches by now?
