I'm sure that in some cases children could teach their parents about Bitcoin. Sometimes kids now more then we know or want to beleive they are involved in. I know some cases where kids were earning bitcoins even with some illegal activities and parents thought they use computer only for playing games and Facebook.
I don't think that who you are talking about are kids anymore. Because when I'm thinking about kids I always think of them in ages 12 or below which still does not have enough cognitive knowledge to learn complex things like Bitcoin, at that age I don't even think that they are interested in earning money. Teenagers on the other hand always wants to find a way on how to earn money just like what teenagers do online.
