Back then all the hype online was mining the coins, which was still very practical back then.

I agree that an online bitcoin isn't going to help you in a survivalist situation because no one will give something of value up like food or ammunition for a bitcoin.

Hell, I worry how useful my gold coins and silver coins would be. Probably must more accepted, but still. Even now I have to pay ridiculous premiums on every transaction of gold/silver at a coin shop.
