The difference is VISA doesn't get a dime from you. Also if you use something like SWIFT and want to transfer money on the weekend you are stuck till Monday. It's also not unusual that oversea transfers take days to complete. Volatility for Bitcoin over 10 minutes is negligible.
So it's a) faster for most people, b) you don't pay big corporations for the transfer itself, c) it works 24/7, d) doesn't track "well" as of now. Those reasons are enough for some people to prefer it over traditional remittance.
