what happens if you die

Me and a friend recently had a discussion, we both love crypto. But then we had in mind like what happens if you die in a car accident or something else in this crazy world today. Would our loved ones know how to access that crypto/money? In our case it‘s a clear NO. Do you „educate“ your loved ones in that case of event or do you leave a kinda old fashioned treasure map? Of course we don‘t hope this is going to happen anytime soon, but you know it‘s always a possibility and it would be a real pity if it would be lost in time and space forever. Now thinking about treasure maps, seems really like a cool idea, have to dig some holes on an abandoned island for my piece of paper with 24 words on it
