It may be useful for transferring money, but not because the technology is inherently better for that. In technical terms, it costs more for a bank to send an email in between branches than to transfer money in between branches. If, using current tech, some U.S. bank would offer transfers anywhere in the world for $0.20 a transfer, they would still make money, and you would feel much more confident that the money will be available for withdrawal. Now, I realize that due to various factors, it is not legal to transfer money to all nations, and there are some nations that dont have the infrastructure to reliably get you cash - but those are not advantages of the tech, they are advantages of the lack of laws. You could build a equivalent, illegal, "bank" with headquarters in, I dunno, Russia? Transfer money worldwide for $5/transfer, and figure out how to avoid the feds. No blockchain, and you have acheived the same.
