Yep, that's what I thought nano had done:
instant, fee's a fraction of a cent, I thought this was it, international payments that don't rely on visa/mastercard!
and then it just went no where :\
Because in practice services like TransferWise solved this problem using fiat currencies with fees low enough not to make it worth bothering with crypto.
Nano is pretty amazing, but, yeah, the interest is in profit not the technology, so it's fading into the background. Pity.
Almost every cryptocurrency starts out with low fees and then fees increase when it gets popular and runs into processing limits.
Turns out nobody is actually interested in transacting with crypto otherwise Nano would have been a winner. I also love Banano, a Nano fork where you mine by folding proteins. Work that has actual value.
