Most of the folks who are into Cryptos are around the age of 30s some even lower than that. I don't really think most of this generation has thought of giving their wealth to their offspring. This concept for them is pretty flawed. These days people want to make sure they live the best of their lives and their children should earn their livelihood and their fortune by themselves.
Are people harsh like that on their future offsprings? Well, if I had children I would do the best to give them confort and life quality. And probably one of the reasons why I don't think about having children is because I know I can't offer them any of those things.
I think it's an egoistical philosophy to want children to pass for the same difficulties they did, just because life wasn't easy for them, so children have to suffer as well.
Once I settle my life, learn a profession, have an income for a confortable and independent life, then I could start thinking about children. Then I wouldn't have to worry in preparing a legacy for them anymore, because it would be already done. All I would have to do was to maintain it until they reached maturity age. If that will be possible someday, I hope it's going to be with the help of bitcoin.
