Bitcoin is a long term project. Therefore it makes sense to save small parts over a long horizon. Do you save Bitcoins for your (grand) child or children?
For those who do not have (grand) children (yet), would you save Bitcoin for them if you would have (grand) children?
I wouldn't prefer to save money for my grand children. Personally, I don't believe in future. I do believe in present.
Agree with you on present, i try to live present life too. But i think he is right. If you have some part of BTC it wont hurt to leave some for future. It can go down and it can go up, its weary risky. But if risk is bigger the gain is too, so i would leave some part of BTC that i dont need atm for future.
The main thing that myself enough, and show the children how to earn money, then they themselves provide, and so on will be passed to grandchildren skills. And because of inheritances are always some problems. So it is better knowledge of their post and not in bitcoin wallets.
