This for sure can be the case. For instance with Stablesats in #[7] you can hold USD value, display it in whatever currency want, and receive (or send) to that balance over Lightning (but you’re just sending and receiving sats).
Displaying in fiat is crucial for enabling circular economies to develop, because converting fiat price to sats all day is a huge hassle.
On nostr, people aren’t pricing things for you to buy, you’re deciding to send a message, a small token of appreciation. Even 21 sats. Wouldn’t hit the same in fiat IMO 🤙
