I am really interested in the space. A friend has launched https://www.imgrateful.io/ and I think crypto (beyond all criticism that we can do) is an interesting option for tipping and receiving donations without the annoying friction of Paypal(s).
Whatever comes after Patreon should be creator-owned like Nebula is to increase the level of accountability it has to its users on both sides.
It's tiresome hearing about crypto's fees, eco, and mining problems while there's a proven technology that's actually spam resistant and nearly consumer-grade actively working, right now.
