If what Bukele expected is that in a few months everyone would use Bitcoin as a means of payment in all aspects of life, he was very wrong, and that warns of a lack of knowledge regarding the use cases. Education, unfortunately, is not one of the best things in El Salvador, and is the cornerstone of an "advanced" society, and when I say advanced I don't just mean technology.
Knowledge and education are very necessary to be able to use "new" technologies quickly and safely. I think Bukele should continue promoting the use of Bitcoin, but solving the problem of school dropouts would be essential in this case, so the new generations would have better knowledge.
