All this ^^^ is right.
I would just add most people in ES only learned what Bitcoin is a year ago, and most of them have yet to really learn what Bitcoin is — if you take my meaning. And with the bear market it's easy to assume (just like non-Salvadorans did in past bear markets) that it won't rise again.
But it is used in all places mentioned. I think I mentioned in that thread, there's a lack of Spanish-language BTC content, and that doesn't help.
