There is a good time to teach crypto and bitcoin knowledge to children, there is a level and of course teaching from an early age will be better.
But what age do you think is the right time to teach kids about crypto, bitcoin?
I don't think it is a good idea to give bitcoin knowledge to children too early. In my understanding, for children to develop in the best and most comprehensive way, they need to be fully educated but it is also important that the knowledge is age-appropriate. It's not that the earlier and more you teach them, the better for them.
Everything needs to be in order just like a child needs to learn to crawl before learning to walk and run. If they don't even know basic financial knowledge like saving, value or how to use money...teaching them how to invest is pointless. Bitcoin is an investment and risky, if misunderstood and used incorrectly the consequences can be dire. So I wouldn't rush into teaching my kids about bitcoin, I would only introduce it when they are truly ready.
