I think you probably need a budget, reaching out to pro-bitcoin people but who are outside of the bitcointwitter-only bubble, people with actual reach and followers know for Other Topics predominantly. These people do exist, they have shows and whatnot, they can be convinced to or be sponsored.
In a more organic way tho, I think bitch@ may potentially bring people in. People in bitch@ meshes forming communities/forums utilising a nostr client which facilitates that.
I can see that happening.
