A cryptocurrency wallet is a ‘storage’ where people can keep their cryptocurrency reserves. A wallet can be a physical device, for instance, a piece of paper, a flash drive, a USB, it can be an online wallet on platforms that offer wallet services, an app that can be downloaded on your gadget or a desktop app designed for various computers. In this article, we will mainly concentrate on cold storage wallets and see what they have to offer to their users.

What is cold storage wallet?

One of the basic concepts a cryptocurrency enthusiast needs to know about is cold storage wallet. Cold storage in the crypto world means merely reserving cryptocurrencies offline.

Cold storage becomes necessary due to security reasons, especially for those who deal with a large number of bitcoins or altcoins.

The reason why it is not recommended to store large sums of cryptocurrency on hot wallets is that those are online storages. In case of online storages, hackers can steal your coins by hacking the online wallet you are using. Many companies that offer online wallets work very hard to make their platform as secure as possible, however, the risk is always there. This is the primary reason, why a lot of people prefer the cold storage wallet options rather than the hot storage ones. When you get yourself a wallet you will be provided with two addresses – a public and a private one. The public address is the one you are supposed to share with the people or companies that you are executing transactions with. As for the private address – you should never share it with anyone. Those who have your private address can very easily steal your cryptocurrencies stored in the given wallet.

The safety of cryptocurrency wallets even varies within the cold storage wallet category. For instance, some devices are safer than the other ones, or some people prefer paper wallets rather than the devices or vice versa.

Types of cryptocurrency cold storage wallets

As it has been mentioned above, there are several types of cryptocurrency cold storage wallets. Those are:

Paper wallets

As you can guess from the name paper wallets come in form of a paper. These are classified as cold storage wallets as the cryptocurrencies stored through this method are not anyhow connected to the Internet. Paper wallets are very easy to generate and they do not cost any money. It is the printed version of your public and private keys on a piece of paper. Some paper wallets may also have a QR code that you need to scan and add to your software wallet for making the transaction processes fast. As offline wallets they are safe from hacks, however, you need to be careful and watch out for damaging the paper, losing it or sharing it with someone else.

Offline hardware wallet

Cryptocurrency hardware wallets are currently one of the most preferred digital wallets due to the high safety features it offers to its users. The hardware wallets usually need to be purchased beforehand and some of the most reputable ones may be quite costly. However, when it comes to safety a lot of people are ready to pay as much as needed. Some of these devices are even waterproof. Usually, similar wallets support multi-signature transactions. Due to the competitive market of the cryptocurrency hardware wallets, which keeps getting bigger and bigger, many companies pay a lot of attention to the design of the products. As a result, many devices have great designs, good screens, small size but at the same time are convenient to use and so on.

Storage devices and sound wallets (e.g. USB drive, CD, hard drive etc.).

The storage devices are primarily keeping your private keys. The sound wallets keep the private keys in encrypted files such as vinyl disks or CDs.

How to use a cold storage wallet?

First things first, you need to get an offline aka cold storage wallet for yourself. Make sure that the wallet you choose is compatible with the cryptocurrency you are planning to store on it.

Paper Wallets >>

Getting paper wallets is a very easy and simple process. All you need to do is:

  1. Choose a website where you can generate a paper wallet. There are different websites that allow people to create paper wallets. When you end up choosing a secure website, make sure to check if it supports the cryptocurrency you are interested in. The process is mainly the same from website to website.
  2. Go to the section called “Create a new paper wallet”.
  3. Start moving the mouse of your computer or randomly clicking on our keyboard to make sure that the sequence is completely random.
  4. A couple of minutes after step 3, you will get two addresses. A public address – the one that you can share to make transactions and a private on – that should stay as confidential as possible for the safety reasons mentioned above. Please note that most of the time when people lose their private address they fail to recover their coins.
  5. You can either print out the addresses or choose the option to print out the QR code whichever one is convenient for you.
