It's a great opportunity for young people, because it will increase their desire to do business, because basically bitcoin is very connected to online business. Well, we just need to direct them not to use it for a negative purpose.
That is a good opportunity for these young people, but the problem is, it will block them to great opportunities that may come to them in the future. Earning bitcoins is not that profitable, it may give you some small profits but it is not enough. And there is a high possibility that these young people can be victim of scammers, because they don't know how the online businesses work and they don't know much about them.
At such young age, when you tell them to earn money by doing something, the tendency of that kid or teen is to find another way to earn more, and that is investing on some sites, that they might not know, a scam or some Ponzis.
