I mean you don't really define what being a "child" means to you. What ages are we talking about here? Yeah I'm probably not going to try and be teaching my 3 year old about how bitcoin works, but once my child got older, and was at the age to be able to learn and understand how money and basic finances work, I would see no problem forcing your kids to learn.
Forget about age for a moment and we all agree that teaching bitcoin is the right step for preparing children when they grow up. Normally parents will know when teaching children in the world of finance by age and they are able to take responsibility for their decisions. Slightly forcing children to be better prepared in dealing with the financial system in the modernization era is important because people don't really have to work hard to make money, because the realm of technology has made it easier for anyone to seek financial gain.
If a single bitcoin can bring them wealth and can set up a business where many people can work, then why are we so worried, reluctant and skeptical to introduce bitcoin to kids. Ah never mind, people will also say we are not right and always want to win alone and force the children bla...bla...bla
Hell most of school across our lives is forced learning, might as well teach something that you can actually use in the real world.
Life is full of theory that is learned in formal schools and this will not educate children directly to practice it. I agree when children are taught anything related to bitcoin and of course when they are able to recognize money to go shopping with friends or girlfriends. But it seems people are worrying too much about bitcoin learning for kids, why? because they think the child will find a way by himself, even though if the parents are unable to direct it, it will not educate them to reach a more precise direction.
