They say to do your Bitcoin transactions offline, and on a computer that doesn't hook to the Internet, or at least isn't connected to the Internet when transacting. I wonder how that works. If you are running a Bitcoin bank, you should probably have nothing else on that computer than the apps you need to run the bank. Better to see through what is going on in the hacking department that way.

Going to the authorities probably wouldn't do any good, anyway, except to give more permission to a different group of thieves.
