San Luis Talpa, zacatecaluca, San Miguel, LA libertard, el zonte, el tunco playa, suchitoto, lake coatepeque, lake ilopango, boqueron, Santa ana, cerra Verde national park, San Salvador, maybe other places I'm forgetting. I travelled alone and did a speed run, yet thorough. That covers areas in the west, east, south and north. Safe to say that's a good enough sampling to represent the entire country. Especially considering its safe to assume the smaller the city the less chance there will be bitcoin businesses. They are using the dollar so it is relatively stable. Really no need for bitcoin right now IMO. Plus it makes no sense to accept payment for services in a temporarily (although it hasn't been lately) depreciating asset if you don't have enough cash flow to support operation costs. Some people are even skeptical of president nayib bukele and don't like him 100%. They had family locked up in the round ups they insist are innocent and think bitcoin could just be for global PR. Despite all this I am optimistic they will come around to it, don't get me wrong.
