I've done several Sat Swaps at bitcoin brunch as a rudimentary test of micropayments. On the weekend of the last bitcoin conference I had several vendors accepting bitcoin with lightning.
I used Muun before. Used it for some donations here and there. Also tested out Kraken's new withdrawal using Lightning.
When I signed up here, I switched to Phoenix since Muun didn't support lnurl-auth.
Now I have ~300k sats ready to spend in my Phoenix wallet and used it for some more donations here and there. Will try to ask some local vendors if they are willing to accept BTC using Lightning in the near future. Maybe as a gift to the normal payment with fiat.
