That is right, we can't just teach these kind of things to kids, we are just being selfish and we just want to teach them what we want, how about their wants, their dreams they have their own paths to take, we must not take it from them. It is better if they can just study first, they will be using and needing that knowledge.
but i think, we don't have to teach bitcoin in completed explaining because i am sure that they will become boring and will leave us without telling anything. i think we can teach them to playing a games with a little explaining until they are curious and wants to know more about bitcoin. beside that, many kids now has very smart about one thing especially in new technology so i think they can accepting the information about bitcoin and understand about what we explained.
