important subject. We often tend to think that death is far away, but anyone can die at any time... so crypto assets must be safeguarded...
never given it much tought, but i think I will leave all my crypto data written down for my wife and son... but I'll have to explain them first on how to use it
in case you are a whale with several children, a good idea would be to split the private keys, leaving instructions on the will (like someone else suggested)
cheers
