I have a paper wallet you can buy for $5. It allows you to hold bitcoins without any risk of them getting hacked, if that's what you're looking to do. See my signature line below, visit
http://www.casascius.com.
I created this as a solution to all the recent hackings and theft. Hackers are stealing bitcoins by breaking into computers and making a copy of people's wallet file. Bitcoins can only be spent once, so if they get your wallet file and spend it first, your copy becomes worthless. But if your wallet file is strictly on paper, they can't get it.
The paper wallet has nine Bitcoin addresses. When you receive the paper wallet in the mail, these addresses are yours. You can have someone send you Bitcoins to any of those addresses, no computer is required. When they send coins to these addresses, the coins are still "out there in limbo", but inaccessible to everyone. They will stay that way safely forever until redeemed by you.
A redemption code (also known as a "private key") printed on the page allows you to spend them later, and as long as you keep it secret, your coins can't be stolen.
The private key and the address are mathematically related in a way the Bitcoin network recognizes. When you re-import the key into a website or the Bitcoin software (when supported in the future), you're able to spend the coins.
If you're wondering where they are in the meantime, the coins are located on what's called the public "block chain" until you redeem and spend them. The website
http://www.blockexplorer.com is a public tool for examining the block chain, and you can see the balance of each of your nine addresses just by doing a simple search there.
I can help redeem your coins to another address with a private key (to others reading this post, please never e-mail me a private key without encryption, or at least contacting me first and letting me know ahead of time). If you have either bought my paper wallet, or can give me a good rating on #bitcoin-otc, this is a free service.
