There are some guides on the net for how to set up a perfectly secure (baring crazy things like top secret cia robot mosquito cameras) wallet to use as a bitcoin "savings account". example: (https://en.bitcoin.it/wiki/How_to_set_up_a_secure_offline_savings_wallet) But they all seem overly complex. Can anyone think of any flaws in this simpler alternative method?

1) navigate to bitaddress.org and "save page as" to a usb drive.
2) boot ubuntu from live cd.
3) make sure the computer is physically disconnected from the internet
4) run bitaddress.org.htm and generate a private key
6) physically write the private key down on a piece of paper and save a text file with a copy of the private key to the usb drive
7) lock the piece of paper and the usb drive away in a fire proof safe

If one can not confer upon another a right which he does not himself first possess, by what means does the state derive the right to engage in behaviors from which the public is prohibited?

If you are going to do that it might be best if you then later typed back in (by reading from your written down version) that private key into say an offline version of brainwallet.org (just to be certain that you didn't write it down incorrectly as that could be a disastor).

With CIYAM anyone can create 100% generated C++ web applications in literally minutes.

Obviously you should be careful, but it isn't a disaster to have to check all possible typos after you realize it isn't right.

True - although the stress of thinking that you even *might* have lost your bitcoins could itself be. Smiley

How about you use Armory offline wallets?  That's precisely why I built Armory, was to make this feature dead simple.  Create a full wallet on an offline computer, make a one-time-ever backup.  Make a watching-only copy for your online computer.  Generate millions of addresses without fear.  Send coins using a USB key to get transactions signed.  It's mostly described in the program itself.

(unfortunately, I would link you to the tutorial on the website, but I just got notification that the website is down for the day.  gah!  you can download the latest version from here:  https://code.google.com/p/bitcoinarmory/downloads/list)

EDIT:  Website backup.  Checkout the Armory Quick-Start Guide and the Offline wallet tutorial.

I freaking love Armory. Always people on the forums asking about features that Armory already has...why aren't people aware?

...
I love offline transactions!
