If I may ask, what's your definition of young age? Do you mean children between the age bracket of 5yrs to 14yrs? Or do you mean teens between the age bracket of 15yrs to 18yrs? Because if you mean teens between the age bracket of 15yrs to 18yrs, then i see nothing wrong if they are been thought about this trending technology called Bitcoin, because the earlier our teens are been expose to this new tech, the more they get interested in it when they grow up. Hence, Bitcoin as a digital currency shouldn't be limited to only people of certain grade or age level, because the earlier we introduce them to this new tech, the more we tend to prevent them from falling victim to Bitcoin related scams, simply because they have already known how the system works.
