If you do nothing at all, your funds will never move after you die. In reality, you're actually taking those unspent outputs out of circulation forever, so you'll be responsible for a tiny increase in bitcoin price... Less supply, equal demand should increase the price

In my case: I have one daughter. She knows where to find my hardware wallets, she knows the pincode and i've taught her the basics. After I die, she'll be able to spend everything I held my whole life.
