Nostr was created by bitcoiners and seemingly adopted first by bitcoiners escaping the dumpster fire that is twitter.

The two systems are independent (with zaps being a bridge). Both share the value of being ungovernable. There is a lot of ideological alignment between nostr and bitcoin. Neither can be censored or stopped. No one has to provide permission for anyone else to use the software.

They benefit eachother and a symbiotic way.
