I think btc tipping is fine and desirable, even the mythical normies I meet own some btc and would like that tipped. (They just don't shout about it). But there are scenarios where content creators need cash for costs, relying on it for income, buy equipment (and they don't fancy the extra steps of conversion). I suppose there are plenty of options already for that tho, drop a Kofi link or whatever in a note. But yeah also maybe integrated as another option in a nostr app would be fine for that requirement too. ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯
