As of now, I do not have any reasons for me to tell my private keys and password to acces my different portfolio and my wallets to my family or relatives because for me it is careless decision. You may have misconception but it is not that I do not trust my family, I'm just afraid that they may use it in not good ways. I know that we humans have not information about when we will die and it is the reason why I have now plan to write my private keys and password and I will keep it in my cabinet.
If in your family no one understands the use of cryptocurrency, then the key access you leave will not function optimally. Start educating one of the people you are closest to and trust, teach the cryptocurrency ecosystem, so that when you really "go" then there is one person who can use it well. It will function more optimally.
I share everything with my wife, I teach her about many things related to what I do in the crypto world. So, one day I "go" first, I feel calm because my wife already knows what she must do. We also keep all important notes related to the wallet in a book.
