Top 5 Bitcoin-Only Hardware Wallets, Reviewed for 2022
Holding bitcoin can be simple, but finding the right hardware wallet to store your coins can be tricky. Web and mobile wallets are usually preferred but have a risk factor of your coins being stolen through cyber hacks or phishing scams. Therefore, hardware wallets are the most secure option when it comes to storing your bitcoin.
In this guide, we will explain how hardware wallets work and list some of the most popular bitcoin-only hardware wallets in the market.
What Is a Hardware Wallet?
A hardware wallet is an encrypted portable device that is used to store your cryptocurrency in cold storage. However, it is not your coins that are stored directly on the device but the private keys that give you access to the coins that remain on the blockchain. Through a hardware wallet, you can conveniently manage your private keys and take self-custody of your assets.
Hardware wallets are effective in securing your crypto by giving you an extra layer of security against hacking, phishing sites, and malware. A hardware wallet, which often comes in the form of a USB device, enables you to access your crypto from anywhere. You can plug a hardware wallet into your computer and manage it through its proprietary software to interact with decentralized applications, as well as send and receive cryptocurrency.
Moreover, hardware wallets can support multiple digital assets simultaneously. For your convenience, different crypto assets can be backed up by a single recovery phrase. The recovery phrase can be used to access your cryptocurrency if your device containing your private keys is destroyed or stolen. That is why it is important to keep a copy of your recovery phrase and store it safely.
Why You Should (Probably) Use a Hardware Wallet
The main advantage of using a hardware wallet as opposed to a software wallet is that your entire bitcoin holdings remain offline. Remember, most theft and scams involving crypto assets happen because the web and mobile wallets are directly or indirectly connected to the internet by default.
When using a hardware wallet, the likelihood of being hacked reduces significantly since it’s a separate device where cryptocurrency transactions are manually and physically signed on the device itself. Only the cryptographically signed transaction hits the internet.
Hardware wallets also often possess extra security features like Two-Factor Authentication, a lock PIN, biometric security, and more. Moreover, the wallet device typically has a display that allows you to enter your PIN as well as confirm your address when transacting.
How to Use a Bitcoin Hardware Wallet
Using a Bitcoin hardware wallet is not that complicated, although they l differ from one manufacturer to another.
- The obvious first step will be to set up your hardware wallet. To do that, you will have to buy a hardware wallet from the device manufacturer. You should do the shopping for the device directly on the manufacturer’s website. Only then can you make sure that you do not buy a manipulated version of a hardware wallet. You can also order a bitcoin hardware wallet on a trusted e-commerce platform like Amazon though this opens you to some degree of counterparty risk as the wallet could potentially be manipulated.
- Once you obtain the physical device, you then proceed to install the custom software that will assist you in setting up your wallet. This you can do by connecting the USB device to your computer. Once the hardware wallet application is running on your PC, several prompts will be issued for you to follow.
- Begin the setup process and follow the prompts to their conclusion. At some point, you need to set a PIN code or receive one. Ensure you securely write down your PIN code so you won’t forget. Equally, be sure to write down your recovery phrase and store it offline in a secure location or several locations. The backup of the recovery phrase will make sure, you will always be able to restore your assets.
- The application will then go on to create the wallet address that you can use to send and receive bitcoin. To transfer your bitcoin to your hardware wallet, copy your wallet address from the app’s front end and paste it into the sending tap within your sending wallet. Initiate the transaction, whereupon you will see the transaction details appear on your hardware wallet.
- You can then check the display on your device that is connected to the PC to confirm the transaction details are correct, and that you are sending your bitcoin (BTC) to the correct recipient wallet. Only if everything is correct, push the button on the hardware wallet to finalize the transaction.
In this example, we are assuming you are using a USB-stick-like hardware wallet device that comes with a display. However, hardware wallets come in all shapes and sizes, so the setup process can vary quite substantially, and some hardware wallets don’t really require any setup at all.
