1) How to start:
Create an offline bitcoin address.This address will have a pair of public and private keys that never connect (until you're ready to spend it). With this guide, we will show you how to make a free cold storage wallet using the paper wallet method.
- While you are on the paper wallet page saved on your PC and while you are disconnected from the Internet, click the Print button. To do this make sure that your printer is also disconnected.
- Print the page.
- Keep the paper wallet in a safe place.
- Reconnect to the Internet safely.
The next step is to add bitcoin to the wallet. As with any other bitcoin transaction, you just need to use a wallet you have online, scan the QR code of the public cold storage wallet or copy the address and send the funds to your cold storage. You can check the status of the funds at any time using the Bitcoin block explorer.
When you are ready to use your bitcoins from the cold storage wallet, you will need to import the private key into a Bitcoin wallet that is online. Any wallet that supports importing private keys will work.
For that, you have to do this:
- Open the client and click Help
- Select the debug window and click on the Console tab
Type in the "importprivkey <bitcoinprivkey>" field (replace <bitcoinprivkey> with your private key and remove the quotes)
- Press enter to import the private key; this will require a re-scan of the
Blockchain which may take a few minutes to synchronize.
Other way to import your private key
Another online wallet alternative that supports the import of private keys is Blockchain.info. To import your private key into this wallet, simply follow these steps:
-Open the wallet online
-Click on Settings and then Addresses
-Click Import Address
-Copy and paste the private key from the cold storage wallet and click Import / Transfer.
