Let your kids know that bitcoin is the surest way to financial freedom, teach them now that bitcoin is of more value than fiat currency, educate them about the importance of bitcoin to mankind,
Yeh absolutely it's an important knowledge for kids to know because due to inflation the value of fiat currency going down which is woory moment for them who hold fiat for future, because after few year same amount of dollars will not worth like now. So personally I will teach my kid to guide them about the importance of Bitcoin and also will teach them that how Bitcoin will safe your fund from devaluation,
I think not providing knowledge of Bitcoin to your kids from now will be a bad decision for you
