In my opinion, I would buy a cold wallet and only my wife and I know it. 5 years, 10 years or 20 years. That's great for my children!
I totally agree. I would store bitcoins for my children and when they grow up, they can fully benefit
It is good to store bitcoin for the long time, because with time bitcoin use to increase in price and get high in demand as well so if you will make bitcoin as a store for the long time, in future you will be very happy, it will not make you suffer lose and lots of money, as fast he life is running it is very important to have something save for your future, so in time of need you will not be worry. Investment is good for you and your children, your family as well.
