Maybe if we explain about what bitcoin, teens will be difficult to understand? The way I explain it is to get them to work on bitcoin pay and after that they will understand about bitcoin 
Actually teens will be easier to teach because they have a great inquisitive spirit than adults. I'm sure if you tell bitcoin with a fun thing they'll be interested in listening and may also be interested in adoptingI agree to the idea that teenagers are the one who are easy to teach but I guess it is quite not cool bevause we all k ow that childrens have different perspective and attitudes when it comes to discussion as well as bitcoin that is very deep and hard to understands for those people who didn't yet know how to handle business and moneys.
