Cold Storage Wallet for Cryptocurrency

A wallet is where you store your coins. A crypto wallet is just that: storage for your cryptocurrency. A wallet for Bitcoin or other cryptocurrencies is essential for storing your digital assets. The most secure type is called a cold wallet.

What is a cold wallet?

Cold storage, in this case, refers to storing your cryptocurrency offline. Specifically, the private keys that actually control access to the crypto wallet, which should never be online.

a Bitcoin wallet, taken too literally

Every crypto wallet, whether for Bitcoin or other crypto coins, has a public and private key. The public key is your address. People need to know it to send you coins. The private key is what gives you access to the coins so that you can withdraw and spend them. That’s why it’s important to keep it in cold storage or, in other words, offline. If something isn’t accessible via the Internet, then it isn’t vulnerable to hackers or malware.

Types of cold storage

In theory, any storage method that involves keeping your private keys offline counts as cold storage. This can range from the latest hi-tech solutions to the downright primitive. Types of cold storage include:

  • Writing down your private keys on a piece of paper
  • Printing your private key as a number or QR code on a ticket
  • Storing your private keys on a USB drive
  • Keeping the private keys on specialised offline wallet software on a computer
  • Using a dedicated hardware wallet
  • A crypto exchange with reserves in protected, secure servers

Cold wallets vs Hot wallets

A hot wallet is a form of cryptocurrency storage that is connected to the Internet. We’ve established that cold wallets are more secure, so why use hot storage for your Bitcoin? Here’s a useful way to think about the two kinds of crypto wallet:

The hot wallet may be more vulnerable, but the risk is necessary for a certain level of convenience.

A hot wallet is necessary to enjoy all the services that we’ve become accustomed to in online banking, such as transfers, deposits, exchanges, and everything to do with money management.

Just like other online services, hot wallets can be secured. Methods like passwords, PINs, two-factor authentication and more are all employed. Of course, these security measures can still be overcome by sufficiently determined or skilled hackers, so the best crypto exchange platforms will use cold wallets in addition to the hot storage required to provide financial services.

Cold storage vs Hardware wallets

Hardware wallets are standalone devices made to store your private keys offline. Trezor, Ledger and Keepkey all make hardware wallets with differing designs. They often come with keypads or limited user interfaces, so that you can access your keys via a PIN or other type of code.

Hardware wallets are very secure, and your keys are even protected when the wallet interfaces with an Internet-connected computer. However, you need to physically have the wallet on hand every time you want to actually use your cryptocurrency, which is inconvenient if you’re an active crypto trader. Cryptocurrency in a hardware wallet also can’t accrue interest.

Cold wallet for crypto exchange

Crypto exchanges manage huge reserves of cryptocurrency, and they also facilitate exchanges, deposits and withdrawals for many users. As such, they must pay extra attention to security. The famous Mt.Gox hack, in which 740,000 Bitcoins were stolen, remains a cautionary tale for the crypto community.

A reputable crypto exchange uses both cold and hot wallets. This is made possible by keeping the majority of the assets in cold hardware (offline data storage or secure servers), protected by security protocols, and only having the minimum amount of cryptocurrency needed for short-term liquidity (withdrawals, etc.) in hot wallets.

Cybersecurity is essential for a crypto exchange

This is akin to keeping physical money locked up in vaults, as opposed to being available over the counter.
