I made a paper wallet for my son and I deposit a smaller amount of Bitcoins there every month. I kept it in a secret place that only me and another person knows.
Then thats great, we dont how long do Bitcoin can survive since it was contunously dumping, but for your it will not end soon or sooner , I guest saving for your children if you have already then its kinda step for beibg secure for their future ,you dont have to stress out yourself if that time was already in your front. In my case I dont have children but I would like to secure my family and I future.
