I go to the library, (with my clothes on), download the "make your paper wallet" site from the library computer (so the computer can't be traced to me) onto a USB stick. Buy a refurbished poo computer from Ebay, Get naked, take a shower just to be sure, put on a balaclava thats been in the microwave to kill the microcameras that might have been put there by the Chinese who made it, get an enema, make the wallets, preferably in a dark room with loud music, print them on a virgin printer, pour petrol on the printer and computer and burn them, put the wallets in an envelope seal it with wax and my coat of arms, and put it in my box in the bank.
Did I miss anything?
But seriously, thank you all for your input, I know OPSEC is important, and I do get more and more paranoid as the price goes up.
Seems like if you put it in the bank, then you still need one other location, in case the bank burns down or something. Whether your second location is your home or another bank, it is not so likely that your catastrophic failure is going to happen at both of your locations at the same time, no?
I am, seriously, going to bury a laminated copy somewhere on my land. And have smaller amounts also in my hidden home safe. (I have a visible decoy safe bought very cheap from Cina with some crap in it).
First off, you people seem to have an inordinate amount of trust in banks. 'Safe deposit boxes' Belong to the bank, just like your deposits. Access is controlled...Not by You.
As for burying laminated paper... Maybe if you live in a desert. Test your lamination in a bucket of water for double your minimum expected burial time, with many test subjects. Plastic is water resistant. For a time. Not for all time. Better to bury stamped stainless, or even stamped plastic if you worry about metal detectors, or if heat is a zero concern (house fire, wild fire, etc.)
To clarify, they would in turn be in a airtight plastic container.
