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.
What a wise decision sir! I agree with this because its the best way you can secure what you want to share with your family. Indeed such a plan with deposits are really good. You may even make several wallets for each of your love ones so that there will be no problem in subdividing it later on. Such investment are worth it.
