Yeah is fine if children are educated about Bitcoin, when they are of age they can decide weather to invest or not to invest, is also a form of education so there's nothing wrong with it, when you educate your children about investment when they come of age they will see the need of investment.
I know of a man who has been accumulating Bitcoin for some years now and he has decided to transfer all his Bitcoin to his children in this kind of case is good to start teaching them about Bitcoin at an early stage of there life, if children are educated about Bitcoin it will be more easy for them to know about it, some people went through a lot for some time just to learn about Bitcoin and some made mistakes along the line so is better to teach children about Bitcoin so when they come of age they will not find it hard or make mistakes.
However when teaching them about Bitcoin please let do it slowly no need to rush them to learn it, they are still children, and what we should teach them are just the basic knowledge about Bitcoin investment and not all about Bitcoin.
A lot of people are of the opinion that there's no need teaching your children about Bitcoin since they will still learn it on social media or as they come of age, now my question is what is wrong in teaching a child the basics of Bitcoin, is a form of education and is a good impactful one since it will help them as they come of age so I see nothing wrong with it.
