Who does? People who sell bitcoin hardware and one small tourist shop in colorado that sells christmas ornaments.
Wow, what utility!
I also occasionally spend money at international businesses on things PayPal, VISA and MC aren't fond of, so short of putting bills into an envelope and sending them it's difficult to do. Crypto solves that for me. It's quick and I don't need anyone's approval of the industry I'm spending money on. It's like cash for local shopping, minus the large acceptance. I'd love to see more businesses use crypto, and for it to be less roller-coaster-y, and to have less energy waste etc, but it is what it is, and it still works for me.
Not at all, a simple wire works , yes , even for porn.
That's getting better, and some day it will probably work globally and near-instant, but we're not there yet.
I mean international money transfer using Bitcoin doesn't work. Currently Wise leads in the international money transfer business and something even better Bitcoin should have arisen if the crypto bros' claims were true -- but there's nothing.
You're not one of them. That's fine, not everything has to include you to be useful.
