fedi / cashu currently solves the first 0-100k sats that, welll now, Zues requires for a self custody LN channel. Lots of nostr noob no coiners will be introduced to bitcoin from these social layers. They will move down the chain not up the chain. Ecash is a good fit for those

I don't see any value in bitcoin without self custody and don't understand those who do. Custodial bitcoin is worth 0. There's much better custodial wallets and tokens.
