I think this is too early for High school students but the right time for college students, but overall this is great for the crypto community. This will certainly affect the future of Crypto currency market, since they have at least a basic knowledge how blockchain works. Unlike the older people today that has a closed mind thinking that Bitcoin/altcoin is just another scam. This students will be the future investors and will surely make the crypto currency market stay for the future.
I very much agree that I think high school students who accept bitcoin skills are far weaker than college students, and that high school life is so interesting. If it is not for their own interest, I do not advise them to learn bitcoin or cryptocurrency.
