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
you are so right,people in youtube just making an interactive videos about bitcoin and trying to explain bitcoin through videos for the sake of this thing
and teenagers would prefer to watch the videos rather than hearing our boring explanation so I prefer on using videos
