This is why I have been using WoS for outgoing zaps. It's the cheapest way I have found, and allows me to zap small amounts to more Nostriches. ⚡
Wallet of Satoshi doesn't work in the US unfortunately. How much are their fees for small zaps though? I understood the lightning network to charge a percentage of the transaction of less than 1%, even going into millisats, I'm just not seeing that with Amethyst + Phoenix.
