It is not Nostr “destiny” to be diverse, nor it is the current tendency.  It depends on the early adopters work… Time by itself -as suggested- works in both ways. Nostr can for sure become more bitcoin radical and “known” for hosting bitcoin centric people in which case it’s not doomed but will be the protocol of the bitcoin tribe and that’s ok (which is not the promise/ideal I think but totally possible) It will depend on how welcoming the network is, over time, how much interesting content on other topics exclusive to the network, etc.
