Cryptocurrency education in high school is too early for them because high schollers are not yet capable for investing and trading in cryptocurrencies, they are still depending on their parents when it comes to financial. But if it will be teaches in college students can be a good impact for young generations or millennials because college students has a capability to sustain their financials by having a part time jobs and as this new generation, the technology evolves and digital currency was made, it should be now a part of education because it is part of economy.
I don't see why a high school student couldn't invest in cryptocurrencies. It's in high school that many people get their first job. While most high schoolers are working to save up for a new car, Xbox, CDs of their favorite bands, a high school kid could just as easily spend their pay on buying cryptocurrencies and then see what happens. It would be important that the kid understand the concept of "what you can afford to lose." But seriously, most of what a typical high schooler earns is going to be spent on what we would categorize as frivolous items. So why not the frivolous item called cryptocurrencies?
If a high school student could be guided into investing in a POS coin such as DMD Diamond, they would be able to start earning a bit of passive income, which I'm sure they would love. Suppose a high school student worked a job (and his parents are still supporting him so no real bills to pay), put all his earnings into DMD Diamond and staked them, and then sold the minted Diamonds and used those proceeds to buy the fun stuff like Xbox and CDs and so forth? That kid would grow up with a very different outlook on money than most. Hopefully he would find several good POS coins that could do that for him, and also eventually be able to get into some good fiat investments. He could potentially be set up for life before he's anywhere near retirement age.
