I would not teach children Bitcoin. They are children after all. They will have childhood only once. I dont want them from very beginning of their life to start to think about "how to earn, how to get a career, where to invest, how to get money and etc". Let them enjoy their life. They have plenty of time to learn, to work in future.
It is the personal right of everyone to teach their children or not about Bitcoin. Children are synonymous with play.
But we as parents also have to be smart about how to approach Bitcoin in ways that are specific to children.
Not like the general ways that make us think hard.
No need to tell them how to get income from Bitcoin, how to mine Bitcoin, or how to invest because we know they won't be able to accept it.
We only need to do a playing method that includes Bitcoin characters in the game, such as using the Bitcoin logo in a guessing game, or other games.
There are still many ways that can be done.
I also won't burden my child's mind with the knowledge that they shouldn't know yet, this is just an introduction.
