For context the only things nostr have in common with Bitcoin is using secp256k1 for identity. It has been cooked mainly by bitcoiners but AFAIK part of the driving force was specifically to avoid the "everything is a blockchain with a native token" situation.

Naturally you will find lots of bitcoin people using and developing clients (hence the Lightning integration on most clients) but apparently it has been picking the interest of other groups. There seems to be a thriving Japanese community.
