How does anyone access the funds of a deceased family member/spouse, if an essential password was stored in the deceased family members brain (e.g. brain wallet)? In terms of security (securing your blockchain assets), this is THE ultimate security risk for loosing all your funds (yes, you will be dead too, but you lost everything, right in the end there), that is overlooked all too often, I believe. What would you recommend, a a private key recovery mechanic for family members?
