it seems like many people are planning to make some inheritance setup but haven't yet. and others are simply hoping their family will dig through their belongings and figure it out. these both sound like recipes for lost coins!
I'm always amazed by how much people over complicate things as well. Instructions hidden here to encrypted things hidden somewhere else, deadman's switches, instructions in your will, etc.
Here's my back up plan: my wife knows the PINs for our hardware wallets, where the seeds are stored, and how to decrypt them. I sleep in the same bed as my wife, our mortgage is combined, our fiat bank accounts are all combined, our car keys hang on the same hook, etc. If she wanted to steal from me or cause me any harm, accessing our crypto would be the last of my concerns to be honest.
Also to all the people saying "I'm young, I don't need to worry about this", you are incorrect. A simple blow to the head or an unlucky infection could give you enough memory loss to forget how to access your coins. Have a back up plan, now.
