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.
its brilliant idea to keep it for the future of my kids....some of my investing in bitcoin is i save to bank because if i kept it in my wallet its not good because sometimes the value of bitcoin is highly volatile and not equaly gain....so for me i rather choice to collect my investment in bitcoin time to time and i'll be the one to kept it for the future of my kids,not only for them but all of us....
