Anytime that this conversation comes up , I will.always say, let kids be kids. We should think that they would miss anything by not learning about Bitcoin at a young age. There is more to their life and development than Bitcoin. Therefore I would not agree to anyone forcing Bitcoin knowledge upon them when they should be taking, music lessons, dance classes, football classes. The only Exception is if the kid show repeated interest in knowing about Bitcoin.
The knowledge should not be forced but it should be out of willingness. I do not care how old my child might be but if he/she is interested in learning and understanding Bitcoin I will teach the child. Just the same way I won't force the knowledge on them it is the same way anyone who has the potential and wants to learn I won't deny being the mentor.
One way or the other I still wish at least one of my children would be willing to learn about Bitcoin.
