Hi there. First post/topic.
I'm about to put coins away in cold storage on a long term, to be forgotten about, basis and have some newbie questions:
1. I understand I can use the bitaddress.org HTML document, copied on a clean USB stick to a live USB version of Linux (Tails) which has never been connected to the web to generate a public address and private key. How do I know that the pair that's generated is unique and hasn't already been generated? What are the mathematical odds of someone coincidentally having the same private key?
2. Is there a "scene" for people using powerful computing technology (high-end GPU's etc.) to generate and test thousands of private keys in the hope that they'll stumble upon some coins?
In short, am I OK to store a couple of coins in a paper document and forget about them for a year or two?
Thanks muchly. I find this site very interesting, even though some of the more mathematical explanations can go over my head.
