You then move the file to a USB drive or something similar in order to move it to your offline computer.

See Table 3-3 for examples of popular desktop wallets. Some advantages of desktop wallets (which fall into the category of software wallets) include the following:

       They’re a convenient choice if you trade cryptos from your computer.

       You aren’t storing your private keys on a third-party server.

       If your computer has never been connected to the Internet, a desktop wallet can be safer than an online wallet.

But desktop wallets do come with some disadvantages:

       Using your crypto assets on the go is more difficult.

       If you connected the wallet to the Internet, it turns into a less secure hot wallet.

       If you don’t back up your computer and it dies, you lose your cryptos.

      Hardware wallet

A hardware wallet can arguably be one of the safest types of crypto wallets out there. These wallets store your private keys on a device like a USB drive. You’re still able to make online transactions, but the wallets are offline most of the time, so you can consider them cold wallets. Check out Table 3-4 for a short list of popular hardware e-wallets.

      

For security purposes, a hardware wallet is an absolute must (and a bare minimum) for large crypto amounts. Keeping a ton of your assets on other, less secure types of wallets increases your risk of unrecoverable hacking attacks. Even safer than hardware wallets are paper wallets (see the next section).

Here are some advantages of hardware wallets:

       They’re one of the safest crypto wallet options.

       They’re great for storing large amounts of cryptocurrencies that you don’t want to use on a day-to-day basis.

      Some disadvantages of hardware wallets include the following:

       They’re the most expensive type of wallet.

       They aren’t as user-friendly as other wallets, especially for beginners.

      Paper wallet

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.
