What is a Cold Storage Bitcoin Wallet?

In the world of cryptocurrencies, “cold storage” bitcoin refers to bitcoin (or altcoins) stored offline. Because cryptocurrencies are digital, this really means storing the private keys offline, where they are safe from hackers.

While the usage of virtual currency is rising in popularity, so too are cases of fraud and hacking.

Unlike with traditional currencies, there is no designated regulatory organization overseeing virtual currency, or any means of legal recourse if your bitcoins or altcoins are stolen. Therefore, the responsibility to protect your investment falls solely on the investor.

Thankfully, there is a way to store your bitcoins and altcoins securely: Cold storage bitcoin.

Cold storage bitcoin is widely considered the safest way to store cryptocurrencies because by keeping your investment off of the internet, you can place your currency out of reach from hackers.

There are several cold storage options for bitcoin and altcoins, such as:

Each of these methods has pros and cons. For example, a paper wallet is not only susceptible to wandering eyes, but if it is hand written, human error or illegible script can be an issue. Those choosing to use physical bitcoin have to put their trust in the manufacturer’s operational security as well as their delivery method.

The responsibility of managing your cryptocurrencies is not to be taken lightly. Owners of bitcoin or altcoins must act as their own bankers, which means they have to make choices to balance ease of access with security. Understanding the available storage options is the best place to start. A cold storage wallet, or “hardware wallet” is a great option, proving both security and easy access to your bitcoin.

What is a Hardware Wallet?

A hardware wallet is a cold storage wallet that securely stores the owner’s private keys in a hardware device.

Unlike software wallets, a bitcoin hardware wallet is not susceptible to computer viruses. Unlike the paper version of a cold storage wallet, the private keys in a bitcoin hardware wallet do not need to be imported to software for access. You can use the cryptocurrency interactively and securely from the device. Additionally, the wallet protects your private keys, making it impossible for them to be transferred in plaintext.

However, there are a few theoretical ways in which a bitcoin hardware wallet could be compromised. As your own banker, it is important to understand every angle of cold storage.

For example, a corrupt production or shipping process could potentially allow for the insertion of a hardware backdoor. As with any computing device, a bug in the hardware, firmware or software could pose a threat. If you are sending cryptocurrencies through your computer, a bitcoin hardware wallet cannot protect you from malware on your computer that is designed to tamper with recipient bitcoin addresses.

At this point, the above mentioned threats are merely theoretical. As of the writing of this article, there have been no documented thefts from Hardware Wallets. For many reasons, bitcoin hardware wallets are generally thought to be the safest method of cold storage bitcoin.
