Yopaki has a fun daily game to earn some sats. You can sign up using nostr:npub1xwwmvty3er863uy9lz03zhc6m9wlzr88f9esywdkq4xjg5en9yyqktl3nz’s promo code “marcelo” if you want. (You can also take the same seed phrase from that and restore it into Misty Breez and try out their Lightning address feature.)
