Rent a deposit box in your bank and in will of bank write name of your loved one so that he can claim all money you have in your bank and also deposit box there in which you can put bitcoin paper wallet as well as instructions on how to get that bitcoin in form of cash in hand because many are still new on using bitcoin.

Better to give those passwords of your wallet to your family first before you die. . or always give those gift and make a note to your table one you die they can read the note for your bitcoins to use from your inherit after you die..

i think just give them your private keys and then show them how to use it and when you will die they will be able to use those bitcoins

Or better way, buy a safe and lock down your private keys there, and use safe key as a necklace. so they can open the safe only when you die!
