I think it is too early for schools to adept crypto in their curriculum. As it is still far too difficult for most people to understand the basics (im not even talking about the technical part). Perhaps blockchain could be mentioned in IT classes but as far as I am concerned, it looks to be too early to dedicate full lessons on the subject. Especially in secondary school where the basics are usually explained and this might be too technically challenging.

Just my opinion though, in the future this could very well become a standard subject. Blockchain that is, crypto's are a consequence of the blockchain technology in my opinion.
