Students should be taught financial literacy first before jumping off to bitcoin knowledge. Financial literacy is like a taboo in grade schools, or even in high schools to some, i don't know why it's not taught there ^{(at least in my country)}. It should be the very thing people should be aware of. Because learning bitcoin ^{(finance part, not on technology part)} will be useless or confusing to those students who will hear it first, it will be like a magic to them.
