A lot of people not interested already in Bitcoin consider it "crypto scam" and it works as a deterrent, not something to attract them.

:) Are there any ideas or ways to tell people about Nostr that you like?

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.
