Cool, Bitcoin is still a speck compared to USD global adoption. I don't think mass appeal in this moment of time is what makes Bitcoin unique. It has more important properties like p2p, permissionlessness, and self custody. These are the things that make it special and without them it is another paypal.

To be fair you keep talking about Monero too so...

Nostr protocol is agnostic and has nothing to do with Bitcoin. Maybe you mean these particular clients.
