Not unlike Whatsapp, Revolut is wildly popular the absolute market leader in its realm abroad while barely an afterthought here in the states. Still, "dozens" is a gross underestimate. Maybe you meant dozens of US based GOS users use Revolut. In that case, I concur. Your point remains understood, either way and you are right about the lacking demand.
Personally, I only use Revolut bc their currency transfer rates are unmatched...by a wide margin, in fact. Super beneficial for frequent/extended international travel.
