I'm quite skeptical of this idea and not so much on the implementation side, which is a challenge for sure but I've seen plenty of bright and enthusiastic people on this forum who could make it happen and would probably welcome a chance to build something inherently positive. To me the more important question is - already expressed by some other posters above me - how do we (or do we even attempt to) entice those who really need that education? We could build the nicest tastiest most beautiful carrot but seeing how many newbies here have a complete disregard for the rules of their "workplace" - how do we get them to eat their veggies without a big-ass stick? If there is one thing we learned from the merit system it's that even when their source of income is threatened (and that's a pretty big stick) some/most folks actively resist any chance of improvement but rather whine and moan about some perceived unfairness.
The idea itself is looking good however when you mention
Introductory cryptocurrency investing
It's already misleading people. Cryptocurrencies are not supposed to be an investment and a speculative asset. This is not the ideology of the cryptocurrency. Otherwise, I should be super rich already.
If you're specifically referring to ICOs, then it should not be called cryptocurrency most of the time. A lot of them don't have any product, or don't use anything using the cryptography
Perhaps not the best title, but the concept is good. It could be focused on what NOT to do, due diligence, risks of irreversible pseudonymous payments, lack of legal recourse etc. Let's face it - people are already being misled in so many horrible ways that any education on the topic would be an improvement.
