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.
You have also a good point here. However, there's nothing wrong if we will start little by little educating them about bitcoin so that they will also be aware that bitcoin exists other than fiat. Once we have seen their interest and the eagerness to get to know more about bitcoin, then it will be easier for them to absorb and understand the essence of Bitcoin in our lives.
Future generations will surely adopt Bitcoin today or tomorrow. But those who are able to exploit this advantage first will be ahead of the rest. I will definitely teach Bitcoin to the younger ones in the family who are old enough to learn. If they learn about Bitcoin from their families, they will be more interested in learning about it from outside as well. On the one hand, as the younger ones will be ahead in increasing their technological knowledge, they will also be comfortable in the financial aspect. Teaching them Bitcoin at a young age means building a hard foundation for it.
