I think anybody that is holding huge fund in crypto should have next of kin in place because death is inevitable. Therefore I don't see anything wrong in giving out private key to next of kin before death.
right, I also taught a number of my brothers to be able to do what I like to do so when I have nothing to replace me so that the crypto that I have can continue to run properly because it is too bad if it only stops us. so if we want to give our wallet keys it is safe because we are close to our brothers.
