Hardware Wallet


I’m sure by the time you get to this point in the crypto space, then you are likely to be in one of the following situation:

  1. You are a serious and long term cryptocurrency investor
  2. You have been hacked by someone
  3. You have the mindset of safe guarding your cryptocurrency from hackers or at least you can sleep well at night
  4. You just want to try one and see what it is like and how is it different from the other type of wallets out there
  5. All of above or none of the above.

So let’s start why you need a hardware wallet and how it’s different. You need a hardware wallet because it acts like your bank, you are in full control of your money, and your private keys are securely stored in the wallet only, can’t be extracted or exported even if you wanted to. The fundamental difference between a crypto hardware wallet and the other is how its private keys are stored and used at the time of transaction. As we all know if the private key is stolen, then your coins are gone. With hardware wallet, your private key always stays inside the IC or Integrated Circuit. The private key never leaves the IC so nobody including the wallet owner can’t even export the keys out or know what it is.

These wallets are designed to keep the private keys safe inside the wallet even if it’s connected to a virus infected computer. This is why it’s extremely safe from hackers. Every use of your wallet on the internet is securely isolated from any potential attacks. Only the person in possession of the wallet can sign for transactions or send crypto tokens by pressing a button to confirm that transaction, not a click of a mouse on a web wallet or mobile wallet.

Hackers are too crazy and they are always ahead of the game, so only hardware wallets have a known history of no successful attacks yet by any hackers.


Generally speaking, all the hardware wallet serves two purposes that is to provide extreme level of security for storing crytocurrencies as well as signing transactions. I like to categorize them into two types; wallets with displays and wallets without displays.

Currently bitcoin.org certified brands are only four of them as follows: Trezor, Ledger, Keepkey and digitalbitbox. They are made in Czech Republic, France, USA, and Switzerland respectively. All of them use open source protocol, mostly BIP 39 & 44 PATH. There is a detail comparison for each wallet below that I gathered.

Something interesting to mention about digitalbibox, they are the only one so far that offers a TF or microSD card slot that is being used to do your master seeds backup. It also supports the FIDO or U2F like the most of the other hardware wallets, see details below.


Always carefully write down your master seeds, normally 12, 18, or 24 English words, write them down on a piece of paper, never take photos of them, or put save them on computers. Keep multiple copies in different places. Let your loved/trusted significant other know about it if you like. Check them once every few months just to keep your memory fresh. Remember: The master seeds are your last line of defense should your wallet is lost, damaged, stolen. Without those master words, you will lose your bicoins or other tokens for good. Nobody on this planet can help you. Your wallet is your bank. Store your fortune on hardware wallets, and keep small amount in your mobile wallet for convenient uses.

Before you make large amount transfers, carefully check the addresses you are sending, be sure it’s copied correctly, you can alway send a small amount first to test. Always keep your hardware wallet up to date with the latest firmware. This is very important.

KeepKey Hardware Wallet

KeepKey was released in September 2015 and was the second hardware Bitcoin wallet to offer a screen. The KeepKey’s larger screen gives it some extra security features that the Nano S and Trezor lack. It doesn’t offer much in comparison to the Ledger Nano S or Trezor. Moreover, it is more than two times in size than its peers, and not so convenient to carry in your pocket.

It has same backup seed key feature with pin code enabled, and it works like the other wallets. At present, it supports six cryptocurrencies (including Bitcoins).
