Not entirely wrong, but the ones really trying to attack remittance markets and doing a pretty good job of it is Alipay, for example. And then we've got all kinds of mobile money solutions in place for years already in countries like Kenya (mpesa is still amazing to me even today).
But you'd be really surprised to learn that Bitcoin remittance is already a thing. It's how I send money home (not directly, but selling my bitcoin instead, for example, is soooo much cheaper than sending dollars home). In fact, choosing to accept Bitcoin as payment and using that to send money home? It's not just saved me on fees, the sell rate is so good I end up sending home a bit more that I sold.
