I was pretty much a kid when I entered into bitcoin. Well not exactly a kid but 16 years old.
Usually there's no need to teach em. Just give them a brief introduction and if they are interested they will learn.
In reality giving them a brief introduction never make them a part of the growing community. Only the self interest keeps them active, so personally in my opinion bitcoin is all about the understanding and the trust of the user. There are successful kids who have turned to be a millionaire just because of the trust they had on bitcoin.
