Hmm, interesting well, as you should know the key is to access the assets, and that key cant be shared if you want security. If you've lost the key or anyone doesn't have it he cant access the Bitcoins in the wallet. So you need to pass the key but there is a huge risk haha, as I had mentioned already if anyone has the key he can withdraw all the funds. More interestingly haha in reality people store Bitcoins for their hiers. I use to keep my keys mostly in a place and few of my family members know where. As you know haha Death is the reality and it can be on the head anytime.
The real problem with Bitcoin
BTC is that if you share your private key with your near and dear ones like your wife and kids, there are chances that they may misuse the funds and even withdraw them before you die.
On the other hand, if you choose not to share the private key with them, you never know if you die all of sudden like in an accident or heart attack and nobody will know those private keys and hence that bitcoin will be lost forever.
I think, in the future many rich families will become poor when someone in their family dies suddenly without transferring the secret private key to anyone.
I agree with the fact that the major challenges of Bitcoin is in it security and transferability which have lead to a lot of attempt conspiracy, take the case of Satoshi Nakamoto for instance, his wallet holdings have remained untouched since his disappearance and if he never return, those bitcoins become waste and lost forever, so in other to prevent such occurrence in our individuals live there is a need to put adequate measure in place to checkmate our securities and how best to transfer our Bitcoin to the next generations without causing any harm to both the receiver and you who is the custodial owner.
The risk of the danger of disclosing your private key to another person, vs. the risk of dying without anyone having access to your bitcoins, has been the major worries of many of us.
