Good point to remember. But isn‘t that the case for any (non-custodial) wallet? Fees are everywhere and with nostr:npub1xnf02f60r9v0e5kty33a404dm79zr7z2eepyrk5gsq3m7pwvsz2sazlpr5 you at least have a clear information about them. Plus, they clearly state in their documentation that the initial transfer should be > 100k sats. Custodial wallets probably don‘t levy such fees because they can sell your info/data and, anyway, they have your sats 😉

This is the crux of the issue - Doing away with trust in light of verifiability comes at a cost, currently - I consider all my sats precious enough to pay that cost to, in turn, better safeguard my sats. Not all will agree, many just might!
I have run fully self custodial lightning before with a node at home, my own domain for lightning address, etc. Let me put it this way, I risk lose FAR fewer sats in custody on a custodial wallet than you risk in fees and channel open/closures. Experimenting with self-custody lightning is absolutely recommended. But you will lose a lot of sats and you will cause other users to lose a lot of sats by recommending they use ZeusPay for receiving zaps on nostr.
No longer recommending the zeuspay ln address - Unfortunately incurrs
high fees. Have a look at non-custodial bridge servers instead, under
