Agree that we have something big developing here, but $3k is a small amount to fund a dev. Like 1 month of living? Your case is also looks exceptional. It's not happening on regular basis so it's hard to rely on it. We have a lot of room to grow.

I think the solution is for devs to monetize nostr apps in some form (or add donate option). The fact that many people have a wallet connected and it takes one click to pay is the game changer.
