It’s going to largely depend on your device OS (ie Apple vs Google vs Windows) I’m iOS so I use Damus primarily and Primal as a secondary client for misc tasks such as looking up npub or note id I want to reference in a post I’m composing on Damus On computer (web) I use Iris or Primal (but 95% of my #nostr use is on a mobile device) For Google most people love Amethyst. I tried YakiHonne for iOS and web and there are features I’m excited about BUT the UI has issues leading to major UX disappointments

You don't need nostr to accept btc, it's just a wallet

Primal. Damus. OpenVibe on #nostr Square. Strike. To a much lesser degree CashApp. & myriad others.
