Investing and finance in general should be in the syllabus; not necessarily crypto, just like how we don't necessarily need the stock market to be a focus, but just a subset. Proper investing and finance is a lot more than investing in cryptocurrencies alone.
Of course, young people in today's world are taught about investing, which may not be open to everyone, but those who study business education are included in the syllabus. Even then anyone who wants to learn about this can take part in various courses.
Cryptocurrency and investing in general should be in different subject or sylabus because if we talk only about investing in crypto, we can't deny the market is unstable and seems a bit controlled by whales and the market is not suitable for investing study.
The cryptocurrency sylabus should be more about how the blockchain system running behind it and the impact to the investors. Or even more how the platform is made with programming concept behind it ( but i think it's more like computer science subject ).
