What are cold wallets

Cold wallets are crypto wallets designed for the safe storage of cryptocurrency assets. Their difference from hot wallets is that they are not connected to the network and are unavailable online. With cold wallets, users can store cryptocurrency assets offline, minimizing the risks of hacker attacks, hacks, and other cybercrime.

Cold wallets are physical devices that often look like USB drives. They are often presented as hardware devices specialized for storing cryptocurrency, or paper wallets, where private keys are stored on plain paper (or any other traditional medium that cannot be connected via a computer). They are ideal for long-term storage of Bitcoin and other cryptocurrencies.

A key aspect of cold wallets is that they generate and store private keys outside internet-connected devices. Private keys to access cryptocurrency assets are kept isolated, making them secure against cyberattacks. When performing cryptocurrency transactions from a cold wallet, the private key must be physically connected to the online device to confirm the transaction.

Types of cold wallets

Let's take a closer look at what types of cold wallets are there and how they differ from each other.

Hardware wallets

Cold hardware wallets are specialized devices for storing cryptocurrency. They provide a high level of security since the program and keys are installed directly on the device, which looks like a USB flash drive with a button or screen. Perhaps the best cold wallets for cryptocurrency are hardware ones, as they have additional security measures compared to the wallets we will discuss later in the article (desktop and paper).

Using a hardware wallet looks like this: the wallet is connected to a computer or phone, after which they log in using the keys for authorization. Then the wallet owner performs all the necessary operations with his assets and, after the session ends, disconnects the hardware wallet from the computer or phone. Even if such a wallet falls into the wrong hands, its security remains high since an additional password is required to start working with it.

Hardware cold wallets are the most secure way to store cryptocurrencies. They stand out from other types of wallets not only for their security but also for their price. Most devices cost around $100-$300, but such an investment is justified given the high level of protection they provide.

Desktop wallets

Desktop wallets are one of the categories of cold wallets that are installed on a PC. They allow you to interact with cryptocurrency even on a device not connected to the Internet. This category includes two main types of wallets: thick and thin.

  • Thick wallets require prior downloading and copying of the entire blockchain of the cryptocurrency with which it is planned to work. It was such a wallet that the author downloaded back in 2015, plunging into how Bitcoin works. Leaving the computer for the night, it was possible to have time to download the entire blockchain. After the operations are completed, the data is again uploaded back to the network, which updates the system.

  • Thin wallets, in turn, do not require downloading large amounts of data. The wallet exchanges information with the blockchain online. Thick cold wallets naturally have a higher level of security. However, thin wallets also provide vital protection and greater security than hot wallets, whose data is completely stored on the blockchain.

Paper wallets

The keys required to access the wallet are stored in printed form on paper. One of these keys is a public, in fact, wallet address, similar to a bank card number. This public key can be shared with third parties without risk, as they can only send you cryptocurrency, but do not have access to your assets.

The private key, like, for example, the pin code from your bank card, must be kept secret. This is an obvious thought - this private key is the key to your funds and provides access to your cryptocurrency assets. You shouldn't show it to everyone.

Keys can be presented as a combination of letters and numbers and in the form of a QR code. There are even special souvenir coins that display your keys.

The Best Cold Wallets for Cryptocurrency

In the author's opinion, hardware wallets are the best for security and convenience. They provide the maximum reliability of your crypto assets and are also quite convenient relative to others.

Hardware wallets are an established market where different companies compete for the title of the best, and as you know, to defeat competitors, you need to constantly develop and offer users advantages that others do not have.
