Financial literacy has been taught in high school or university, so what's the problem? not everyone interested in cryptocurrency and many governments aren't friendly with cryptocurrency, it don't need to be introduced as a subject. But some universities had added cryptocurrency and blockchain subject from
few years ago and still exist until right now.
That being said, it's important to approach trading with a cautious and disciplined approach, as the cryptocurrency market can be highly volatile and unpredictable.
Most people are lose in trading, I'd say it's better for people to learn about hard skill e.g. engineering, agriculture, accounting, etc than trading because not everyone are successful by learn trading.
