I do not see anything wrong with teaching a kid how money works and why bitcoin is a superior form of money, after all knowledge about the economy will be way more important and useful during their lives than the majority of other knowledge that could be imparted to them, besides it is not like this knowledge has to be taught in a dry manner, as we could use one of the many board games in which money is an integral part to teach those principles and teach them about bitcoin at the same time while they are having some fun.
To be honest, those kids that have the edge are the ones introduced early on to money matters. At a young age, they learn and understand the importance of money. Not just about earning and keeping it but also in investing it. Do people think that the rich gets richer because they'd just pass on their wealth to their kids easily? I don't think so, they also teach them about money as they grow older.
Teaching to invest and to learn something new about Bitcoin is a good thing while the kids are young. They are on that period where they like to learn new things and discover it as they grow older. While this is a technology and finance combined, that is an interesting thing for them to learn. Well, my retirement and wealth distribution to my kids might not be on scheme but I'd just teach them first about how to keep their wallets safe and how to retrieve wallets through private keys.
No one denies that teaching bitcoin to our children is not good, but we also need to wait until they reach the appropriate age, you cannot teach bitcoin to your children when they are only 4 to 5 years old. At an age where children cannot even perform basic multiplication, division, addition and subtraction and do not understand the importance of money. Teaching bitcoin to children too early will have no effect, and can even ruin their childhood when we deliberately cram them with things they don't need to use yet.
Can any of us know what bitcoin will be like in 10 or 20 years? And is it necessary to educate our children about bitcoin when we still don't know what their world will look like? We don't need to be in such a hurry, let's give our children the best childhood and teach them when they are ready to learn, don't force or impose on them.
