This article focuses on storing cryptocurrency on a traditional USB drive and explains not only the benefits of this method but also how to do that.

Can you store bitcoins on a flash drive?

Flash drive or so-called USB drive has been a number one device for storing data for several recent years, but currently, it is being gradually replaced by cloud storage. However, this functional device has acquired a new important feature - it is widely used as reliable cold storage for cryptocurrency. It is a convenient and easy-to-use hardware wallet that does not actually store coins. But it keeps the information about user private keys or other important credentials required to access Bitcoins or another cryptocurrency you have purchased. At the same time, it is absolutely possible to create an offline wallet on your USB drive and make transactions with its help too.

Why store cryptocurrency on a USB?

It is a widely known fact that both crypto exchanges and web wallets are not considered safe storage for cryptocurrency since they can be stolen by hackers in case of their successful attack. They have already raised huge amounts of cryptocurrency worth millions of dollars and these losses cannot be fully recovered or compensated due to the decentralized nature of cryptocurrency. 

Cold storage like USB drives is considered to be one of the safest storage for cryptocurrency in the modern digital world. Why you may wonder? There are several reasons to confirm this viewpoint.

1. Theft prevention

Cold storage means you keep your Bitcoin reserves offline, so there is no constant Internet connection with it. Hot storage wallets like web, mobile or desktop can be easily attacked by viruses, malware, and bugs because of their online presence. It can also lead to the theft of user private keys and seed phrases due to their vulnerability to attacks. Being also called gap devices, cold storage wallets have isolation from unsecured networks due to the physical distance between a device and a computer. 

2. Low cost

There is hardly a new crypto investor who agrees not only to invest in a digital currency but also to purchase a quite expensive hardware wallet considered one of the most secure ones. Experienced crypto holders know about the Trezor or Ledger hardware wallets that support numerous coins but cost over $100 and should be ordered in advance due to their great popularity. 

A USB wallet is a cheap alternative to these innovative devices since you can take any flash drive you have for this purpose. Even the first flash drives with a minimum of storage space can become a reliable crypto wallet since a BTC private file does not take more than 256 Bits. It means there is no sense to look for a flash drive with much space, but you should definitely prepare it for becoming a wallet by removing all other files and downloading necessary software.

3. Availability

A customary USB drive is sold in many shops and does not require pre-orders or paying high delivery fees thanks to its popularity. They are also appreciated by compact design and ease of use as well as compatibility with most computers.

4. High-security level

Even if you once lose or damage your crypto stick, it won’t take much effort to recover currency with the help of private keys and a seed phrase. The last one is 12, 18, or 24 words long and can be a great backup for any information.

Another feature of a flash drive that improves its security is encryption. There are several examples of software that can be downloaded for this purpose and users can take advantage of built-in encryption tools provided by Windows.

5. Offline transactions

Though it seems quite strange for many crypto enthusiasts, flash drive wallets allow users to process transactions in a safe manner using private key files. It means you can prevent your financial details and other important credentials from exposure to potential hackers and malware.

How to store bitcoins on a flash drive

You can send Bitcoin to USB if you set up an offline crypto wallet there. How to do that? The most popular software for this purpose is Electrum wallet. However, prior to downloading and installing software, you should prepare your USB for becoming a safe wallet. Therefore, start with the first step and move forward gradually to achieve the goal.

1. Create a bootable flash drive

It should be one with permanent encryption storage. Tails can be a good choice for that. Prefer an unused flash drive that has been formatted and does not store any other files.

2. Download Electrum software from the official website and install it on your computer

There are wallets for Windows, Linux, Python, Android, and iOS. You can find links to any of them here. Before you begin the installation of the software onto the USB drive, it is necessary to disconnect the computer from the Internet. There are two ways to do that: direct unplugging and desktop connection disabling. 


3. Plug a USB drive and run a wallet installer to save it on this flash drive

It usually takes a couple of minutes to complete the installation process. When you are offered to choose the destination to install Electrum to, find your USB drive and select it. When the setup is over, invent a strong password and a seed phrase you won’t forget to secure your wallet. Apply changes to the wallet settings if you need any. 

4. Use the safe eject feature to remove your USB drive and reboot a computer

Don’t hurry to take your USB out since you can damage it if not ejected safely.

Now when your wallet is ready, there are two tips from crypto experts to consider:

  • Make a duplicate of your USB drive for extra security.
  • Set up an operating system to the USB drive to eliminate vulnerability to malware.
  • When your wallet is fully protected and can be used for operations, you can fund it with cryptocurrency or send funds to another wallet by completing the following steps:
  • Switch off your Internet connection.
  • Take your USB drive and plug it into the computer.
  • Open your wallet and generate a transaction using the private key file.
  • Remove a flash drive safely.
  • Turn on the Internet connection again.
  • Complete your transaction.

As you can see, your private key is never exposed to the Internet connection, so it contributes to a higher level of security.

Other hardware devices

Undoubtedly, a better but also a more costly alternative to a USB crypto wallet is a hardware wallet. Similarly to flash drive these types of wallets store a private key that opens the lock to the address on the blockchain. They are also characterized by super security, support for multiple assets, convenience, and wallet-to-wallet trading. These devices are immune to computer viruses and private keys are stored in a microcontroller-protected area, and so they can’t be transferred out of the device in plain text.

 They have a little different algorithm of work since you should not only plug the device into the computer, enter the PIN code, and create a transaction using a private key but also confirm one on the screen of the device used.

The most popular type of hardware wallets nowadays is Ledger Wallet. Its Nano S model is the world’s most popular hardware wallet with state-of-art security. It can be combined with the Ledger Live app to get the full power of crypto possessed. All company products combine a Secure Element and a proprietary OS designed specifically to protect user assets. 

The first Ledger product was launched in 2014. Currently, there are two most popular models called Nano X and Nano S. Each of them is made of brushed stainless steel and plastic with a USB connection. They are compatible with Windows 8+, macOS 10.10+, Linux, and Android 7+. Nano X model is also compatible with iOS devices and supports over 1,500 assets.

As you can see, there is an easy-to-use and secure way to store cryptocurrency, especially if you start with a Bitcoin flash drive. This can be an affordable solution for new crypto holders as well as used as a backup device too. No matter what hardware wallet you choose, it will be secure and convenient storage for your assets.
