I think teaching or convincing chidren regarding this system is not a good idea in which they may be at risk since bitcoin involves huge amount of money in which children doesnt know yet on whats going on with it. Talking about teenagers I think we are the part of induatry who can be neasily adopt bitcoin knowledge since we was born and growing up with technology who typically part of our daily lives nowadays, bitcoin involves profit and ai think most of the teenagers wont bother to try since it will help them to sustain themselves and help their parents too.
