I'm ultraparanoid. It should be my username...
I have my wallet on my Linux box who's / is under 4 concurrent layers of DM_crypt. I ran that system before I ever heard of bitcoin. I'm not doing anything illegal, I just don't think my business is anyone's damn business. I take my wallet offline with a flash drive using TrueCrypt. I use the triple cascade encryption option on a file container. I even use that tiny new lexar echo drive and geocache a backup of the wallet in a similar container file. It's tiny, and even if somebody finds it, what can they do? That degree of encryption is just stupid. I'm considering a MicroSD geocache instead, it's even smaller.
If I could do that to the cash in my wallet, I would. You can't hide cash in a geocache as an off-site, off-line backup, and still be assured of it's safety. BTC is the best.
I only wish I could find someone local to buy BTC from w/ cash... The locator services are useless. If the forums had a geographicaly organised section, it would be a dream...
Incredible! With that much encryption, changing your username is almost prerequisite...
