Wow, okay, so I need to learn more about this Boltz thing.
So if my main use case is receiving, then I could just create a lightning invoice in Boltz, give it a btc address, and then receive the sats to the btc address with a .5% fee from Boltz, and an on chain fee?
Maybe that's the way to go...
Though I guess you'd want to batch things up, so you don't pay too much in on chain (mining) fees.
