children doesn't need to know about currency,but teenagers does,and i think there's so many explanation video in youtube so don't wasting effort wasting your time when you can just give them about the link of video so they can learn from it,whether they will be interested or not,it's definitely depend on them
Indeed, for me there's no need for children to learn about bitcoin because I do believe that children must play because they are in the stage of playtime. But teenagers must be known about this because they have already a daily expenses to sustain. When the time on explaining about bitcoin you could only give some link on youtube according to a certain topic.
