Get your self a Ledger Device, and a stack of Metal Key Cards. Etch your Keys for each account into the metal. Make two copies. Store your Ledger in a series of fireproot “Russia doll” devices make to hold serveral inside one another. Buy some BTC. Cold storage. It’s your in hand pocket Swiss bank account.
In fact, I’m preparing to purchase several ledger devices. I am going to put 1/10 of the BTC on each one of them. I have the 3x thumbdrive Pill Case style heat/fireproof contianers on the way. I think if I use three per device and then keep them in a safe or buried they sould stay safe from destruction.
I have written up some legal documents for distribution of my BTC to certain individuals in my family. These will require each person recieving a ledger drive take training and demonstrate use of the device (with a second device and $50 worth of BTC) on them before they can take possession.
One of the things I want to do is have 1/10th BTC provided to each of my children every few years to ensure they will continue to enjoy a comfortable lifestyle.
There is actually a market for Ledger’s where people buy them at 18-10% premium simply to take possession without anyone knowing they have it in cold storage.
Hopefully your heirs are smart enough to say thank you—and then cash them out immediately.
Lol.
