Every platform or protocol has to start somewhere. Nostr was founded by and is being developed by hardcore Bitcoiners. It's obvious that it's going to attract more like minded folks. Plus, there's the fact that Nostr's ethos melds well with Bitcoin's ethos. Nostr is a screaming beacon of decentralized freedom, making all Bitcoiners eventually migrate to the protocol. Every platform or protocol needs a base. Wether it's Bitcoin maximalists or boating enthusiasts. Eventually, other groups of people start seeing it's benefits and start to check it out.

I've told Udi before and I'll say it again, bring your community here. Build here. The vast majority of Nostriches welcome new users.
