For me kid are not good to teach about bitcoin you only waste your time since they are not interested yet about earnings much better to teach them to learn more in school but not about earning.
Good point mate. Most kids are more into playing and studying and it's really a hard job for you to interest them in bitcoins.. they won't understand it until they will become independent from their parents and live on their own. Kids are not matured enough yet.. you may interest some but not a lot.
