Well, most of us here on nostr trust custodians. You and I both use alby for zaps.

If you're from a developing country and can only save modest amounts, you can't save with on chain Bitcoin or pay for your own lightning channel. Or if we want the whole world to hyperbitcoinze, there isn't enough block space. And so a trust trade off needs to be made to scale. 

 For sure. I guess I wouldn't put an amount on lightning I wouldn't be willing to lose. Same as Fedi I suppose.
