Those who really care about normies and growing nostr then are going to be for USDT zaps.
It's insanely hard for the average person to acquire "a little Bitcoin" in any form, be it lightning form or Cashu form (if you call Cashu a form). Strike doesn't even have debit card support anymore for goodness sakes. People just can't get the stuff, and no, begging nostr old-timers for a few handout sats is not a solution.
The best path for growing nostr is USDT, because normies can actually GET A HOLD OF IT. Nostr doesn't run on Bitcoin like Farcaster runs on ETH , at best Bitcoin is just a plug-in, and USDT is a more useful one.
