Your question probably didn't reach a single person that could answer it.

Nostr users are less than 1% of internet users probably. Many, perhaps most, don't use English.

Believe it or not, for most of us in the world English is not native or even primary language.💡

Nadaring your question shows that less than 6% of 980 relays queried have your note.

Of those it did reach, only a tiny fraction are in Spain.

Of those only a tiny fraction even know what lightning is, much less use lightning even once in a while.

And so on, because of rubbish nostr propagation...👎

To have any chance of reaching someone with such questions, have to at least put the #asknostr hashtag and #LN #hispano #Spain for that question specifically.
