Review of the Best Cryptocurrency Hardware Wallets: Ledger, Trezor, Keepkey, CoolWallet, and Bitlox

A cryptocurrency hardware wallet is intended for “cold” storage of digital money, which means without constant access to the Internet. All user’s private keys are stored remotely and are not moved to any servers or even to the network. Outwardly, the device looks like a flashcard and does not occupy much space.

The review provides descriptions of the best crypto hardware wallets as follows:

  • Ledger
  • Trezor
  • Bitlox
  • CoolWallet
  • KeepKey

In terms of reliability and usability, hardware wallets lead among the other ones. Security is provided by three algorithms:

  • a PIN code for access to device management;
  • a password that opens access to the account balance;
  • a secret phrase that allows you to recover your password in the case it was lost.

Your funds are kept offline until a cryptocurrency hard wallet is connected to the computer. But even then, you will need to enter a password to manage the balance or send transactions. Therefore, even if the device is lost or stolen, the new owner cannot do anything with it.

Ledger Hardware Wallets

Ledger was founded in 2014. The founders of the company are eight specialists in the field of cryptography and business. At the present day, the number of employees has grown to 130, and offices of the company are located in several countries around the world.

Ledger Nano S

Ledger Nano S

Ledger Nano is the most popular crypto hardware wallet in the market in 2018. The cost is $59. 

It supports the following cryptocurrencies: Bitcoin, Ripple, Ether, Litecoin, Dogecoin, Komodo, and more than 40 other in-demand coins.

Pros: 

  • The high reliability due to encrypted storage of private keys on the device itself
  • A proprietary Ledger Live interface for easy wallet management
  • A wide and regularly updated list of supported currencies
  • The ability to connect a second account with your own password and PIN code
  • A robust and compact body

Cons:

  • Problems with conducting microtransactions. You will either have to accumulate large amounts or use third-party services.
  • Ledger Nano S is considered to be the best option for storing Bitcoin or other well-known cryptocurrencies. 
  • The developers have tried to make this crypto hardware wallet as simple and convenient to use as possible, without causing damage to security.

Ledger Blue

Ledger Blue

Ledger Blue is a premium cool hardware wallet. The large touch screen enabled a full user interface to be incorporated into the device. The price is $285. 

It supports the following cryptocurrencies: Bitcoin, Ethereum, Ripple, Stratis, Bitcoin Cash, other popular coins, and all ERC-20 tokens.

Advantages:

  • The lightweight with a fairly large size (almost of the palm)
  • Locking the device after three unsuccessful login attempts
  • A high level of comfort thanks to the touch screen
  • Equipping the screen with really working scratch protection
  • Operation without recharging with the screen turned on for three hours

Disadvantages:

  • An inconvenient way to enter a key phrase
  • The screen turns off after 30 seconds of operation (this setting cannot be changed)
  • Screen flickering when being turned on. By the way, this problem was promised to be fixed in the last batches
  • The possibility of errors with displaying address formats

In general, we can say that the Ledger Blue crypto hardware wallet does not surpass Ledger Nano S in terms of the security of storing cryptocurrency. The overpayment is for increasing the comfort of use, and whether it is worth it – everyone decides for himself/herself.

Trezor cryptocurrency hardware wallets

Cryptocurrency hardware wallets under the Trezor trademark are flexible and compatible when you need to go from offline mode to cryptocurrency exchange.
