A paper wallet is a super-cold crypto wallet; see Table 3-5 for examples. To use it, you print out your private and public keys. You can send funds by transferring the money to the wallet’s public address, and you can withdraw or send your currencies by entering your private keys or by scanning the QR code on the paper wallet.

Some of the advantages of paper wallets include the following:

 They’re ultra hacker-proof.

 You don’t store them on a computer, mobile phone, or third-party server.
