You should add paid services to your relay to help cover running costs.  Maybe also set up a tip wallet.

Don't ignore monetization just because you're early.  It's easier to go from paid to free than the other way around. 

 I don't plan on running a public relay. I'll whitelist with my domain and certain pubkeys for my relay. I did think about applying for an open sats grant though. 

And if I ever get around to it, I would run a public relay with configurations for cost per kind event insertion. 1 sat per kind 1, 10 sats per kind 3, 0... Etc. using lightning or eCash to top up credit, right through the frontend.  

 I love the idea of buying credits and tracking usage per npub, I think that's a good strategy.  Keeps out the riff-raff 😆
