I'm pretty sure crypto will be taught in schools in several years, not as a single subject but at least as a part of economy\banking\computer science course.
There are already teachers' initiatives who decided to give their students some info about blokchain and cryptocurrencies (I heard about this in some British schools). These courses are not obligatory, but they give the evidence of a rising interest in crypto, especially with the new generation.
Yep I think that the European countries are the one that are more open and liberated about cryptocurrencies and it's really good to know that they are at least already introducing it in school. It does not really have to be an individual subject like what you said but it's good enough to do some basic ideas teaching.
