For long-term storage of bitcoins (or giving as gifts) it's not safe to store your bitcoins in an exchange or online wallet. These types sites are regularly hacked. Even keeping a live wallet on your own computer can be risky.
Be your own bank.
By printing out your own tamper-resistant bitcoin wallets and generating your own addresses, you can minimize your exposure to hackers as well as untrustworthy people in your home or office. Just transfer your bitcoins into your new wallets, and use common sense to keep your wallets safe the way you would jewels and ordinary cash. Or give them away!
The Bitcoin Foundation contracted with BitcoinPaperWallet to design a limited editioncommemorative paper wallet design for distribution at the 2014 IFCA convention. You can also provide your own JPG images to create one-of-a-kind personalized wallets.
What's special about this design?
1. Tri-Fold Template
This bitcoin key generator guides you to print both a front side and a back side for your paper wallet. All sensitive details on the front side (the private key and QR code) are folded up and securely taped shut so as to stay hidden. For additional security, you can seal your wallets with the tamper-evident serialized hologram stickers available for purchase on this site—though any sufficiently opaque (light-blocking) tape will work fine.
2. Tamper Resistant
One risk with a paper wallet is that someone with physical access to your wallet may "sneak a peek" at the private key and withdraw your funds without your knowledge. This wallet's folding design and obfuscating security patterns resist "candling" -- the process of shining a bright light through the paper to reveal what's printed inside. Serializedhologram stickers guard against stickers being removed and simply replaced with new ones.
3. Perfect for Giving
Want to give bitcoins to someone who isn't tech-savvy? Need to send bitcoins by mail? Use a pre-loaded paper wallet. The sealed-shut folded design helps to ensure that the recipient won't accidentally reveal the private key. For recipients unfamiliar with bitcoin, the reverse side of the wallet has printed instructions for checking the wallet balance and withdrawing funds.
