Self custodial lightning has proven itself so far to be a bad solution for tips on nostr, as much as every bitcoiner may wish the situation was different. Bolt12 doesn’t fix that because the receiving wallet still has to remain online to receive payments and still has to have adequate incoming liquidity. A mere handful of people in the world are going to bother dealing with that. Everyone else will continue to use custodial solutions. Liquid is proven and reliable especially when compared to other options like fedi and cashu. Maybe that will change over time, but for now I wouldn’t touch cashu/fedi zaps with a 10 foot pole for anything beyond small play amounts until they’re more proven. Liquid isn’t perfect either, but it’s preferable to running and maintaining a lightning node.
