We need not think that far because young children certainly do not understand bitcoin. And if we tell bitcoin sure they are also difficult to understand. If we tell adults about bitcoin would be easy to understand because they would be interested because they would think of the benefits. 
yes and still they do not need to understand bitcoin, as bitcoin is currently use as investment and therefore teenagers do not have to do anything with investment, as they are depending on their parents for living and when they become independent t then they can start using bitcoin for investment or for whatever they want to use bitcoin.
