A Bitcoin paper wallet is an offline method of storing your cryptocurrency by printing your public and private keys on paper. This form of “cold storage” keeps your Bitcoin safe from online hacks, making it an attractive option for long-term holders who prioritize security over convenience.
What Is a Bitcoin Paper Wallet?
A paper wallet contains two key pieces of information:
-
Public Address: Used to receive Bitcoin.
-
Private Key: Grants access to spend the Bitcoin stored at that address.
These keys are often printed as both text and QR codes for easier use.
Advantages of Using a Paper Wallet
-
Offline Security – Immune to online hacking, malware, and phishing.
-
Low Cost – No need to buy a hardware wallet.
-
Long-Term Storage – Ideal for holding Bitcoin without frequent transactions.
Risks and Limitations
-
Physical Damage – Paper can tear, fade, or get wet.
-
Loss or Theft – If someone finds your paper wallet, they can spend your Bitcoin.
-
No Password Recovery – Losing the private key means losing your funds forever.
