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.
There is nothing wrong in educating high school students about cryptocurrency, As long as they are willing to absorb the importance of earning money, because time will come that they will be facing this obligation. Eventually, they will become concern citizens and obviously will need all the knowledge they can get in their nations assessment for development.
