Yes, planning ahead of all uncertainty in the future, wether death, sickness, disasters etc is very important, nobody can tell what will happen tomorrow. Life is very short, we can not determine the time of death, it may comes at a younger or older ages.
Planning for crypto assets for the future is very necessary and the those you handle all your assets should enlightened as time (life) progresses. We may have trusted family members and friends to be in possession of wallet keys, and for the married, you can handle your wallet keys to your children, but we should endeavor to teach them everything about Bitcoin and the blockchain technology.
