Having an easy way to send money around the world without having to worry about which currency it should be in would be a huge help for some communities. A lot of artistic/creative groups work on a kind of semi-gift-economy model where everyone buys everyone else's stuff, not quite as an arms-length market-value transaction but as a semi-social interaction where you buy things from the people you hang out with online at what's probably more than a "fair" price. Having something like Patreon but less US-specific and more closely integrated with social media (admittedly Patreon's integration with Discord is starting to fill that gap) would genuinely help.
It allows anyone around the world to send and receive money instantly and at low cost.
