What is cold storage in cryptocurrencies?
When cryptocurrencies are no longer in use, they are "refrigerated". Every cryptocurrency wallet, whether it's Bitcoin or any other cryptocurrency, has a private key and a public key. Cold storage helps protect your crypto assets from hackers and malware attacks.
If a thief attempts to steal the hardware, you can prevent him from obtaining your funds by creating a PIN code. You can even recover your money by entering a backup code or a recovery phrase.
The advantages of cold storage
It is an excellent place to store a large number of tokens for a long time.
It can keep money away from network servers and ensure its security.
Disadvantages of cold storage:
Carelessness may cause external damage, but if you have a recovery seed phrase, this damage can be recovered.
For beginners, setting it up can be a challenging task.
Compared with online trading, this is not an ideal choice for quick and daily transactions.
Here are some of the most popular cold storage options for cryptocurrencies:
1. Cryptocurrency hardware wallet (the safest
A hardware wallet is an electronic device that uses a private key stored offline to sign transactions. If the device is damaged or lost, it also allows you to recover your funds using the backup seed key. Hardware wallets are the safest cold storage option for cryptocurrencies, but they are not cheap.
2. Paper wallet
A paper wallet is a way to store cryptocurrencies offline. It involves printing the public key and private key on a piece of paper in the form of a QR code. Every time you need to make a transaction or exchange, you can complete it by scanning the code. Since you store the key in a place far away from the network server, the possibility of it being stolen is minimal.
It must be noted here that paper wallets are not suitable for partial fund transfers. When transferring or using part of your funds, the private key of your paper wallet must be imported into your desktop wallet. Some paper wallet providers offer tamper-proof designs to enhance security. Due to the offline nature of paper wallets, they are completely immune to malware, viruses and hacker attacks.
After setting up the paper wallet, it is necessary to ensure that the website code can run offline. After the paper is printed, you can put it in a sealed plastic folder, laminate it or store it safely in a bank vault.
3. Cryptocurrency storage on a USB drive
One of the simplest ways to refrigerate tokens is to use a USB drive as a cold wallet. You can use it to export the private key and save it to a USB drive. However, this option has a drawback because anyone who can access your USB can access your cryptocurrency.
4. Desktop wallet
A desktop wallet is a client that can only be accessed through your computer. In an offline environment, they can be used to export files containing encrypted private keys. The private key is stored offline on your computer in these software programs. However, when you receive or send funds through them, they are online.
Digital (hot) wallets and cold wallets
A digital wallet, also known as a hot wallet, is another type of encrypted storage connected to the Internet. Here are some of the main differences between cold wallets and hot wallets:
Security: Cold wallets are more secure than hot wallets. Although hot wallets can offer a high level of security, their online nature means they are vulnerable to hacking.
Convenience: Hot wallets are more useful. They enable you to send and receive cryptocurrencies quickly, while cold wallets sacrifice speed to ensure security.
Cost: The vast majority of hot wallets are completely free. The most common type of cold storage is the hardware wallet, with prices typically ranging from $50 to $150. However, since the encryption key can be stored on paper, free cold wallets can be created.
