It’s a great idea but in my POV as service provider it’s hard to set up.
Thanks to nostr:npub1xnf02f60r9v0e5kty33a404dm79zr7z2eepyrk5gsq3m7pwvsz2sazlpr5 it was easy to set up a node and use it when needed, but the costs of the service I‘d need to offer it as payment method exceed the use atm.
I’m still looking for solutions in regards of self-custody and process payments to really live up to the standard „be your own bank“
