IMO, the biggest mistake of all #Bitcoin/#Lightning wallet and app developers right now is not integrating the most naive version of a #Nostr based contact list. 

Literally we have everything we need to easily select and send bitcoin to people, projects, clients, etc and establish very simple web of trust security. AND to have a #Nostr identity created within a wallet by default for those that don't have one, even in the absence of caring about social posts or notes or whatever. 

As I learned very recently, npubs are literally taproot addresses, so legit every bitcoin wallet could generate a nostr ID for those that don't have one and if you punched in your nsec into the app, anyone could receive coins straight to their npub by the app merely auto-removing "npub..." and replacing it with "bc..."

This is SUPER low hanging fruit that completely shifts the user experience of bitcoin and I think extremely few people have realized just how big of an improvement this would be. 

My advice: Stop thinking about #Nostr purely as a twitter replacement, think about it as a #Bitcoin account, username, & reputation system, it actually works and scales BETTER for that use than for general purpose social media.
