As much as possible, you want to ensure your crypto assets are safe and protected from cyber-attacks. Cold storage crypto wallets are one of the investors' top-tier options for keeping their coins. This article will explain why the cold storage method is a preferred option and how it works.

What Is Cold Storage?

Cold storage is a term common in the food industry to refer to edibles prone to spoilage in a short period. These consumables are stored in cold storage environments, which preserve the items and increase their shelf life. So what is cold storage crypto wallet used for?

In crypto, cold storage wallets are not used to keep coins from spoiling but from hackers. These wallets are called cold wallets, and they are offline crypto wallets used to keep cryptocurrencies without connection to the internet.

Although an internet connection is required to send your assets to the wallet, it is not required to store and hold them. Once the internet connection is removed, the chances of a hacker stealing your private keys and accessing your wallet are eliminated.

The development of cold storage for cryptocurrencies was facilitated by the constant occurrences of private key theft leading to huge crypto asset losses. Today, crypto users bank on cold wallets to secure their assets and stay safe from thefts.

How Does Cold Storage Work?

To understand how crypto cold storage works, let's look at its design and functionality. Most cold wallets are designed to be hardware devices. They depend on the internet only to receive or send crypto assets from or to a web-based wallet. On the other hand, hot wallets are web-based wallets used to receive, send and store crypto coins while remaining on the internet.

Each cold wallet has two types of keys; public and private keys. When you use cold wallets, your keys are kept offline and inaccessible by anyone on the internet. When you connect your hardware wallet to the internet, the public key is required to identify the wallet address enacting a transaction, similar to how an email address helps differentiate one person from another.

On the other hand, the private key grants you access to receive or send cryptocurrencies in your wallet. After which, you disconnect your device from the internet, and the information on your public and private keys goes offline and remains in your cold wallet. Some of the best crypto cold storage include Ledger, Ellipal, and Trezor.
