I do not think bitcoin should be introduced to children, because children still have to understand the lessons for their age in their school. If the kids have an interest in the financial system and banking I think the kid has the potential to be introduced to bitcoin.
Yes I agree with you. Children should enjoy their childhood while they have it because there comes a time that they need to think about their future like paying their own bills, etc. You have a point to introduce it to children but only if they are also interested in learning about bitcoin.
