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.

Our kids represent the leaders of tomorrow, let's teach them about bitcoin now that we can.
I wouldn't say surest really, maybe "most accessible". Because a lot of ventures out there provide long-term profit without the high volatility bitcoin entails, but the thing that sets bitcoin apart from them is the fact that it is easily accessible, even by a toddler with half-a-brain to search in the internet. As long as you have a working internet connection and some money, you can buy bitcoin easily. And there are multitudes of lessons and guides as well on how to flourish in this industry, from trading, to making your own project. This is very different from other ventures out there with trade secrets they don't want to divulge to some nobody. But again, at the end of the day, they are all equally profitable and when done right, would lead you to financial freedom. Be very careful with instilling information to your kids.
