My advice: don’t do marketing for Nostr. Have you ever seen advertisments for a protocol? It doesn’t make any sense ;-)
I’ve created a repository where you can find all the files and assets I used: https://gitlab.com/sebastix-group/nostr/nostr-ads. I would like to encourage everyone to re-use these for other (new) marketing purposes which the protocol doesn’t need 😉 I would love to see other weird places with Nostr ads.
