I think libertarian Bitcoiners are dominant.
Discussion
Perhaps but maybe it's more subtle.
Being aware of Central Banking, and The Financial System, or Supporting Bitcoin necessarily imply someone's political affliation, as ironically enough supposedly Democrat voters own the most Bitcoin, libertarians are really high, and Republicans are low but the party supports it way more.
Bitcoin is kind of Bi-Partisan in all honesty.
Nostr isn't all bitcoin holders. Nostr is predominantly bitcointwitter expats. And bitcointwitter is by and large libertarian.
I would Bitcoin is the primary dominating ideology of Nostr, though there are Monero users, which in all honesty are basically Bitcoiners too.
We'll see how Nostr's political scene evolves, I imagine it'll probably be bridge wars of Mastodon vs Nostr if any political activity happens.
Too early to tell but I hope to imagine discussions can be better on here.
