For beginners venturing into Bitcoin paper wallets, this guide demystifies the process—from understanding its utility to executing each step securely.
What Is a Paper Wallet and Why Use It?
A paper wallet is a physical document containing the private and public keys of a Bitcoin address, enabling offline storage of BTC holdings. It’s a cost-effective, hacker-resistant solution that keeps keys cold (offline), ideal for long-term savings or gifting.
Before spending BTC from a paper wallet, a "sweeping" process is required to transfer funds to a hot wallet (e.g., mobile or desktop). Note: Hardware wallets like Ledger or Trezor bypass sweeping.
Step-by-Step Guide to Creating a Bitcoin Paper Wallet
Step 1: Secure Your Computer
- Run a full antivirus/anti-malware scan.
- For advanced security, use tools like Tails OS (secure boot disk) or Glacier Protocol (multi-device setup).
- Disconnect printers from the internet.
Step 2: Download the Wallet Generator
- Never generate keys online. Use Bitaddress.org offline by downloading its ZIP file (includes a local copy of the site).
- Verify the author’s PGP signature for authenticity.
Step 3: Go Offline
- Disconnect all devices (PC, printer) from the internet.
- Use Chrome or Firefox with extensions disabled.
Step 4: Generate Wallet Keys
- Open the extracted
Bitaddress.org.htmlfile in your browser. - Move your mouse or type random characters to generate entropy.
- At 100% randomness, your Bitcoin address and private key will appear.
