I think that's a misstatement; I'm fairly certain that AES works well as a composite function (with non-related keys), altho' I would personally use a second cipher for the second round. Even in the case of the 3DES MITM style attack, 3DES remained more resilient then just DES, just not 3x as effective.
I missed the part where you explained why it's a misstatement.  . It's note barely useful, it's useful, just closer to 80% useful. Depends. For znort987, I recommend a chain of multiple ciphers for composite encryption, and unrelated random keys.
If the user can secure the key of such system, he could as well secure the bitcoin key directly. Depends on his setup. But I like the comic! |

If your neighbourhood gets hit by an EMP, where do you think you will get the electricity to run your computer with on which your bitcoins reside(d)?

Agreed. If a nuclear EMP happens your way you're gonna have *plenty* of other things to worry about, like, oooh, WHY IS MY SKIN FALLING OFF?  ?? |

Google Faraday cage,
you can buy little bags or large bags that can protect your Thumbdrives and HHD, SSD or what ever from the end of the world.

Do common metal safes work like faraday cages? If yes, that's a nice 2 for one deal...

presumably, but only if the metal is grounded. |

What? EMPs aren't magic devices that permanently disable electricity by hacking reality... |

They do, in a way. Depending on the material used (specific conductivity, magnetic permeability and thickness) and the severeness of the EMP they protect to a certain degree. |

presumably, but only if the metal is grounded. Grounding is of no concern. |

FWIW, modern data centers have EMP protected walls.
The datacenter where my servers are also has a flywheel UPS for short power outages, and a diesel generator that can supply power up to 4 days for longer ones.

They don't disable electricity but they can fry the stuff that brings electricity into your home
