Depending on the point of view of the students, it will be good for them to know so early in the phase of their life.
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.
Yes, I agree with what you said, that it's too early for them to study that kind of thing and focus on primary subjects that inevitably will help them, especially in the future. But it depends on the country/ curriculum of the schools because they want to teach their students the economic factors that can be done using cryptocurrency, and also, this is their new way to teach and view the emerging currency.
