At nowadays.. I think it's not worth it if the young are just having fun and spending money, it's time the young are more advanced and can earn their own income more independently until close to a success and can helping the finances of its parents.
I have partial agreement with you because you are talking about all the investment and earning opportunity for the youngsters but you are thinking about their real life work and education as well. You know what it is very important to have formal education for time being because it gives us some sort of respect n our life and no once can say that we are uneducated. Believe me such instances do happens in the world and in some countries that rate is huge. Why im discussing all this? Well its simple that if youngsters come to know far easier way of earning money, in this case if it is bitcoin then they might get distracted may leave their education far sooner than they soul not. So for avoiding such things I am pretty sure they must not get involved on large scale.
