Open Source Hardware Wallet

Those who do not yet know what a Hardware Wallet is should read the explanation. Bitcoin Hardware Wallets are considered the safest way to store your own Bitcoins.

At the same time, the bitcoins can be actively used. Beginners make no mistakes with a hardware wallet and do not risk a total loss of digital currencies.

Here, the individual Bitcoin Hardware Wallets were examined and compared with each other. The test winner has been determined:

TREZOR One – Open Source Hardware Wallet

The Trezor Bitcoin Hardware Wallet is the prehistoric Bitcoin Hardware Wallet. Although the Trezor One weighs only 12 grams and is 60 x 30 x 6 mm small, it does a great job.

The code of the Bitcoin Hardware Wallet is open source and therefore publicly available. This has the advantage that hackers can try – which they will – to crack the Bitcoin Hardware Wallet.

Up to now, all security gaps, which were not really alarming, have been closed as quickly as possible.

The design of the Trezor takes getting used to and does not appeal to everyone. The price is in the range of 130 €¹ and is more than reasonable for the features it offers.

Although the Trezor One costs more than the Ledger Nano S, the Bitcoin Hardware Wallet still ranks first, which speaks for the Hardware Wallet.


The SatoshiLabs company behind Trezor One also deserves recognition. It works professionally, actively uses the social media channels and publishes factual reports on updates and security problems.

The Bitcoin Hardware Wallet does not only support Bitcoin. More than 12 currencies and ERC20 tokens can be used with this device.

Ledger Nano S | The inexpensive Bitcoin Hardware Wallet
Half open ledger Nano S The ledger Nano S is ranked second. The Bitcoin Hardware Wallet costs 94 €¹, making it the leader when it comes to value for money.

The device has a nice design, an easy to use interface and this hardware wallet supports more than 23 currencies and ERC20 tokens.

The Bitcoin Hardware Wallet is 98 x 18 x 9 mm and is about the size of a USB stick. At only 16 grams, the Nano S is not a heavyweight either.


Ledger(Wallet) is SatoshiLabs’ biggest competitor. Unfortunately, this criticism is not so well handled by the competition.

Security problems are more likely to be swept under the carpet and dismissed as harmless than discussed openly and objectively.

Another, often mentioned criticism is that the code for the ledger products is not open source. This leads to a feeling of security, although it is not possible to check whether the code is really secure.
