Do you guys BIP38 your paper wallets?
I do. BIP38 is a important feature in paper wallets. It protects against theft of your Bitcoin and is relatively hard to crack if you use a strong one. However, you do have to remember the password. The best practice is to write it down and keep it somewhere safe.
I am for some reason extremely paranoid of storing in paper wallets long term. I have the feeling that I would eventually screw up. That I would lose the paper, unless I did a ton of copies or something. But something could happen, like a flood, or some guy going into my house and stealing it or something. With digital copies, you can have thousands of copies anywhere you like, and encrypted and hidden so they don't even show up as a wallet file.. seems more safe to me than some piece of paper.
To prevent such damage from theft or natual disasters, use a reinforced safe that is both water and fireproof. You can encrypt your paper wallets too, no problem, there is even a BIP on that. With digital copies, it is much more suseptible to corruption and theft. Even with the wallet files renamed, it is still a very expensive method.
