You work as a teacher, you should teach students according to the curriculum and subjects at school, Bitcoin is digital currency, not good, teach and introduce children in school too early with money, what they need is knowledge, about school subject matter, and don't mix them with digital currency.
Today is sophisticated with existing technology, the younger generation in general they are familiar with Bitcoin or crypto, without being taught at school they already know it, it's a fact, I think, teaching them professionally about general school knowledge, automatically they will easily get to know Bitcoin in the future.
