I believe highschool is too early for them. Instead of studying on such thing, they should more focus on vital subjects particularly math and science because they are the most difficult ones. If studying crypto will be added in the curriculum then it would be much appropriate in college. Hmm, maybe this can be added on Basic Economics and absolutely on those who are taking Commerce related courses.
