Not your keys, not your coins.
This is already enough and if ever i do hold up that huge amounts of coins then i will surely think of first on how it would be inherited by my loved ones when i die.
A simple message nor a video tutorial or show up some links on how to open a bitcoin wallet and how to convert or spend it up would really be better compared if
we do just tend to use up 3rd party services or some sort.
We cant trust up no matter how reputable they are and can you assure that they would give out your coins once you had passed away? I dont think so yet
everything can easily be denied on.
i dont like it aswell . its risky to trust someone because you will not know what happen to them in the future and worst they can take your coins with them .
the most safest way is to hold your private keys with you and if you want it to inherit with your family , just educate them first so that theyl know how to decrypt a secret message because we dont want to write our keys on a simpliest manner to avoid being stole by unathorized people
