The dream of every successful businessman or woman is to have a good successor. you can not be in the light in which bitcoin has brought you to and allow your children to suffer because you failed to teach them the secret behind your wealth. 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, let them know that bitcoin has changed the economy of countries who saw the light in it and adopted it as a means of doing transactions.
Don't ruin your child's childhood just because of the ambition to pursue financial wealth, but you must teach children how to solve the problems they started, at the right time and when they are old enough bitcoin will enter as a solution to financial freedom and that is the right time to introduce bitcoin to them. Trying to teach children too early to get to know bitcoin will have a psychological impact and the worry is that they will be lazy to go to school and are more concerned with money, at certain age stages it is not recommended to introduce children to money that exceeds their ability.
Now that your kids are young and vibrant, be their tutor, ensure they are bitcoin oriented, save them from financial dependency, encourage them to rely on bitcoin instead of saving fiat currency that Depreciates now and then.
When your children are in their teens, I agree that teaching them bitcoin is much better than saving in the bank, but the concept is that we also have to enter the learning stage about volatility and bitcoin also has risks if not invested properly. Every parent will definitely give the best for their child and I believe if they don't get the same opportunities as us in bitcoin it doesn't mean they ignore it, but sometimes direction will find its own way for them in facing financial problems.
