Cryptocurrency “Cold Storage” Explained For Beginners! (w/ CRYPTOTAG Titanium Backup)

A device the size of a USB that has a metal casing for extra durability. The general design is very simple and compact, and its interface is incredibly easy to use. This device operates through Ledger Live, which is a desktop app that allows interaction with the device.

This device is notable not only for its portable design but also for the number of coins and tokens it supports. It supports over 1,000 coins and tokens. This includes Bitcoin, Litecoin, Zcash, Ethereum, Ethereum Classic, Dogecoin, and Dash. In addition, it supports a wide variety of ERC-20 tokens. Moreover, the device can interact with online wallets like MyEtherWallet, Electrum, and Mycelium.

Its potentially more secure from potential hackers thanks to the physical buttons that are necessary for executing transactions. It possesses a tamper-proof feature that frequently checks the integrity of the hardware wallet every time it turns on.

What Is A Cold Wallet

A cold wallet is a cryptocurrency wallet that is not connected to the internet. With cold storage, the generation and storage of the private keys is done in an offline environment. Online environments are vulnerable to hackers, who therefore actively attack online crypto wallets. Most exchanges and brokers have a large part of their cryptocurrency in cold wallets. This makes it impossible for hackers to steal the cryptocurrency from the wallets, because you need to be physically at this location.

This also means that not everyone can quickly withdraw all cryptocurrency from an exchange. An employee first has to collect it from the cold wallet and send it to the hot wallet. How this exactly happens is unknown. All the exchange I asked keep this a secret. The opposite of a cold wallet is a hot wallet.

For users it is also possible to store your cryptocurrency in a cold wallet. Take a look at the popular cold storage options below.

Basics Of Bitcoin Wallets

Before we can understand cold storage, we must first explore the concept of a bitcoin wallet. For the cryptocurrency user, wallets function in a somewhat similar way to physical wallets which hold cash. They can be thought of as a storage device for cryptocurrency tokens. However, in most cases wallets are not physical items, and neither are the bitcoin they hold. Rather, they are digital storage tools which have both a public key and a private key. These keys are strings of cryptographic characters which are necessary in order to complete transfers of bitcoin to or from the wallet in question. The public key, analogous to a username, identifies the wallet so that other parties know where to transfer coins during a transaction. The private key, similar to a password, is the wallet’s owner’s special access code and acts as a security device to help ensure others cannot access the bitcoin stored within.

There are various ways to secure a bitcoin wallet, the popular ones being encryption, backup, multisig and cold storage none is infallible though. The first way is to encrypt your wallet by using a strong password. The second way is to make a backup of the wallet. Even a computer malfunction can result in a loss of bitcoins, let alone hacking. Multisig is another method is to protect bitcoins. It involves creating a multi-signature transaction system under which more people need to approve the funds being released.

Public Adress Public Key & Private Key

Youve probably heard these terms being thrown around with crypto when talking about cold and hot wallets, so lets get into their meaning:

Public Adress: This is what you send to other people who want to pay you with crypto.

Public Key: This is a long string of numbers generated by the private key, it is used by the wallet to make the public address.

Private Key: This is a long string of numbers that allows you to access your crypto whenever youd like.

In summary, the private key is an extremely long string of numbers used to derive the public key. The public key is also made up of a long string of numbers so it is compressed and shortened to form the public address. Thus, the public address is a hashed version of the public key, and the public key is a public version of the private key.

This is why you only need the private key backed up, everything is derived from it. Most devices will offer a seed phrase so that you dont need to remember the private key. But, again, make sure to keep this away from ANYONE. Dont share your seed phrase with anyone because it is the equivalent of your private key.

Although cold wallets are storage devices, the other purpose they serve is signing transactions.

This is similar to signing a check and giving it to a person!

How To Set Up Bitcoin Cold Storage

Crypto Cold Storage

In this guide we will walk you through setting up your very own cold storage wallet. Before diving into the process, you may be wondering what is cold storage? In simple terms, cold storage refers to keeping your Bitcoin completely offline. Cold storage, also known as a cold storage wallet, is the opposite of a hot wallet where your Bitcoin is kept online. Since Bitcoin is a digital asset, keeping them online increases your risk or attack surface for having your bitcoin stolen when kept online using a custodial service. By keeping your bitcoin in cold storage, your attack surface is greatly diminished.

Getting started

The first step to getting your Bitcoin into cold storage is creating an offline Bitcoin address. This address will have both a public and private key-pair which never goes online . With this guide, we will show you how to make a free cold storage wallet using the paper wallet method.

Why Cold Wallets Are Superior To Hot Ones

If youve read the whole tutorial up to this point, youre probably thinking – how can cold wallets be superior? They are worse than hot ones!. Well, there is one simple reason which makes cryptocurrency cold storage the way to go:


Cold wallets are the staple of security when it comes to cryptocurrency storage.

I have purposely kept this part out of the hot and cold wallet overviews. I have done this because it truly is so important that it deserves a section of its own.

Hot wallets are the most vulnerable wallets in the world. All of the digital walletsstore your security keys and codes in their online servers, which are extremely vulnerable to hacker attacks, scamming attempts and other ill intent-driven actions. Sure, most of the high-profile hot wallet offering sites and companies have major security measures put in place, but all it takes is the smallest loophole for your savings to be gone forever.

When it comes to digital crypto storage, there is only one option worth considering – insurance. Sites like automatically grant you 100% insurance if you choose to trust them with your cryptocurrencies, which is a very rare and reassuring option.

When thinking about appropriate crypto storage wallets, security should be your number one priority. Who cares if you get the best free wallet available if you are left broke and empty-handed just a few days later? The best cold storage wallets are most definitely the safest ones, too.

Why A Cold Wallet Is The Best Crypto Storage

When you buy crypto, you have a few different storage options:

  • Keep it wherever you bought it. Some of the best cryptocurrency exchanges keep coins in their own cold storage for security. However, this still isn’t recommended. The exchange will technically have control of your crypto, and there’s also the risk of your account being hacked.
  • Move it to a hot wallet, which is a digital wallet on the internet, a computer, or a smartphone.
  • Move it to a cold wallet, which is any type of storage not connected to the internet. The most popular types of cold wallets are hardware wallets .

Both hot and cold wallets store your private keys, which are what give you access to your crypto. If someone else obtains your private keys, they can steal your crypto.

What Is Crypto Cold Storage

Normal, online digital wallets, whether provided by a crypto exchange or a third party, all require internet access. That’s why they are typically called “hot wallets” by the community. Although they are safe enough, a lot of investors aren’t comfortable with keeping their crypto in third-party apps rather than keeping it in their own hands.

That’s where cold storage comes in. Cold storage simply means taking your cryptocurrency and transferring it into an offline storage vehicle. This most commonly refers to a hardware wallet, like the Ledger Nano X, in which users transfer their crypto onto the USB-based hardware wallet. Once stored there, you can put that hardware wallet wherever you want and access it later.

The benefit to crypto cold storage solutions is that they are impossible to hack. While someone could crack Coinbase one day, they can’t hack into a secure USB that’s not connected to the internet. However, there are disadvantages to hardware wallets as well. This includes the possibility of damage or simply losing them.

Best Of Both Wallet Worlds

How to Move Crypto QT Wallet to Cold Storage

Given the trade-offs when using either type of crypto wallet, a combination of cold and hot wallets is usually ideal. You want to strike a balance between the accessibility of a hot wallet, and the peace of mind and security of a cold wallet. Many will end up with several versions of each: an exchange account hot wallet, a mobile hot wallet, and a hardware cold wallet. Each crypto wallet can be used for a specific purpose, thus creating a balance between ease of use and security when using and trading cryptocurrency.

Another popular trend is using a second phone that functions only as a mobile crypto cold wallet. When using a cell phone as a cold wallet, you would only turn it on when you want to make a transaction. The secondary phone acting as a cold wallet is then connected to your primary phone via bluetooth or WiFi and funds are transferred to your hot wallet for the transaction. After the transaction is made, the WiFi or bluetooth connectivity is turned off and the secondary phone is powered down.

Many find this more convenient than a hardware wallet, while also offering the peace of mind that comes with knowing your cryptocurrency is safe and secure. This method of using a secondary phone as a cold wallet would be more secure than a typical mobile hot wallet but less secure than a hardware cold wallet. This approach would typically store an intermediate amount of cryptocurrency.

Dont Support All Cryptos

Another common disadvantage is the limited support of different cryptocurrencies by each wallet. This means that the wallets may not be able to hold all kinds of crypto because they dont yet support them. This is very common because the number of cryptocurrencies is growing faster than the options of wallets that support more crypto varieties.

Hardware Cryptocurrency Wallet And Cold Storage

Many people are confused over a hardware wallet and cold storage as a way to store your bitcoins and other cryptocurrencies. The difference between Hardware Cryptocurrency Wallet and Cold Storage is mostly in wording though. It basically means that Bitcoins and other crypto are stored offline, i.e. that your private key is nowhere stored on a computer that itself is connected to a network such as the internet. Lets evaluate these main differences between hardware wallet and cold storage in the crypto industry and explain in more detail what they mean.

A hardware wallet is a small computer device that is used to store cryptocurrency. According to some it is a form of cold storage because the wallet itself is not connected with the internet and the private key is not stored on a server, phone or any other computer. Another form of cold storage is by writing out your private key on a piece of paper, this is called a paper wallet. Most people use a paper wallet as a backup in addition to using a hardware wallet.

Cold storage is just the name for any method where your private key is not stored on a networked computer where it could be stolen from: it can be as simple as a piece of paper with your private key written on it.

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 , protected by security protocols, and only having the minimum amount of cryptocurrency needed for short-term liquidity in hot wallets.

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

Benefits Of Cold Storage Vs Hot Storage

Why store your crypto assets in a cold wallet? The advantages of cold storage dont only boil down to security – theres myriad benefits that users can reap.


Being the major concern for holders, the protection of hot wallets is under question. Even major exchanges become the victims of fraud and hacking at least once. This means that your assets might be stolen without compensation. Besides, errors in smart codes also contribute to vulnerabilities.

24/7 access

What will you do if the famous crypto exchange you entrusted your crypto savings to suddenly becomes inaccessible? Hacking, attacks and technical maintenance might create downtime. With crypto asset custody services and cold storage, you can avoid such problems.

No limits

Some platforms impose strict limits on deposits, withdrawals and on the account balance amount. With a hardware wallet, you are free to hold, send and receive as much as you want without the hassle of KYC procedures.

Offline access

Some devices and platforms for cold storage allow for offline access . This feature comes in handy when one needs instant access to the cryptocurrency.

Safety in the long-term

While some exchange platforms and their wallets might cease their existence because of hacking and attacks, cold wallets are not accessible to any third party. If you plan to hold your crypto assets for many years to come, cold storage is the best solution.

Which Crypto Wallet Should I Buy

If you’re storing a large amount of cryptocurrency, or plan to “hodl” for a long period of time, it’s a good idea to invest in a hardware wallet. After all, if your investment is going to be worth thousands of dollars more than you invested in the years to come, what’s $100 or so now to protect it?

The best crypto cold wallet for you, very much depends on how in-depth you want to get with the technology, what other security measures you have in place, and how many hoops you’re happy to jump through to protect your Bitcoin or other cryptocurrency. The Trezor Model T or Model One represent some of the easiest hardware wallets to protect your cryptocurrency, without requiring heaps of technical know how. The Ledger Nano S is slightly more secure on the hardware front, but Ledger itself has had some backend security scares worth taking into consideration.

If you want the best cutting edge security, the Coinkite Coldcard is the best hardware wallet, but it is a little more complicated to use and setup. If you already have a hardware wallet but want to further improve your security, a metal backup for your seed phrase is the best way to go.

Hot Storage: Whats The Difference

Hot wallets refer to any type of cryptocurrency wallet that connects to the Internet. In general, these wallets are very easy to set up and access and they also accept more types of tokens. With that said, they can be vulnerable to hackers, possible regulation, and certain other technical susceptibilities. While cold storage is more secure, hot wallets accept more cryptocurrencies and provides a higher level of usability than cold storage options.

Overall, the primary distinction between a hot wallet and a cold wallet is one crucial thing: Internet exposure. Investopedia editor, Jake Frankenfield, explains that:

There are different reasons why an investor might want his or her cryptocurrency holdings to be either connected to or disconnected from the internet, and so its not at all uncommon for cryptocurrency enthusiasts to hold multiple wallets, some of them hot and some of them cold.

People who want to trade or make frequent purchases with their cryptocurrency assets will often choose a hot wallet over cold storage. But often, they only store the amount needed for the short term, with the bulk of the digital assets safely cold stored away. This is usually due to holdings in the cold wallet are not transferable across the Internet. Be that as it may, hot wallets tend to face security issues much more frequently than cold storage methods.
