Hi all. What are considered "best practices" to ensure a paper wallet is as secure as can be for cold storage? I realize the paper itself is vulnerable to fire, water etc. And to be sure to guard your private key from view of people and cameras. But I've also heard about needing a special printer because most modern printers have memory in them that saves what you print and that can be compromised. Also an "air gapped" computer using something called "iceberg protocol" or something like that. Can someone tell me what is the best way to set up a paper wallet?
I actually wouldn't use a paper wallet. I'd get a small USB stick and create a text file. Then add the private keys to the text file and put the text file on the USB stick.
Throw the USB stick in the safest place you can imagine and you've got yourself secure holding.
