Bitcoin Wallet on a Budget?


Ledger Nano S is the most popular cryptocurrency hardware wallet (more than 1.4 Million units sold). The Nano S is the most secure and affordable option to store cryptocurrencies. This review will help you decide if the Ledger Nano S is the right hardware wallet for you, looking into elements like security, design, mobility and supported coins. This year, Ledger released a new model called the Ledger Nano X.

However, the Nano S is not obsolete and in our opinion is still holding strong. It is still a good choice for casual cryptocurrency traders who do not trade a lot of altcoins, or those want to store their cryptocurrencies in multiple devices for security. The Ledger Nano S retails for USD$59.

Key features of the Ledger Nano S

  • Top of the line security to keep your cryptocurrencies safe and secure from hackers.
  • Affordable price- suitable for beginners who want a cheap and reliable hardware wallet.
  • Unique staking features so you can EARN cryptocurrency whilst keeping them secure. Learn more about staking here.

Staking and earning

Ledger Live allows for staking Tezos ($XTZ), Tron ($TRX), Cosmos ($ATOM) and Algorand ($ALGO). Users can lock up their cryptocurrencies and in return they get interest. This feature expands Ledger into more than just a secure place to store your cryptocurrency, it can even help you grow your digital assets.

Staking your digital assets can be done in 3 simple steps. First, freeze your assets by logging onto Ledger Live, choosing the relevant account for the asset you wish to stake and click “earn rewards”. A popup window will appear. There you will be allowed to select the amount in your wallet you wish to freeze. Secondly, vote for your validator(s) who will be making the blocks on your network and the cryptocurrency earned by making these blocks will be redistributed to voters. Lastly, claim your rewards by clicking “Claim” in your relevant account. Rewards are claimable every 24 hours.


Ledger has released a Ledger Swap feature which allows users to exchange their cryptocurrencies through their partner Changelly. How this works is you send your cryptocurrency from your device to Changelly, who will send you back the swapped cryptocurrencies.

To use this feature you will need: Ledger device, Ledger Live, the app for the crypto you want to swap and receive, and finally the exchange app.


Ledger is working with Compound ($COMP) to allow users to lend DAI, USDT and USDC through Compound’s decentralised finance (DeFi) protocol. The purpose of doing is is that the lender could earn an Annual Percentage Rate.

There are numerous benefits when using Ledger to lend:

Control: You have control and proof that the crypto you lend and generated interest belong to you. This is because this feature is done through Compound, and when you lend on the platform you get “cTokens” in return. cTokens represent proof of your ownership of the cryptocurrencies lent and the interest generated. These cTokens are stored by you until you want your lent assets and interest back, and in which case all you need to do is to send the cTokens back to the smart contract.

Security: cTokens are stored on your ledger hardware wallets.

Convenience: Compound’s lending features are available directly through Ledger Live.

Lending crypto using Compound and Ledger Live is done in 3 simple steps. Firstly, on Ledger Live’s Manager, install the application for the cryptocurrency you want to lend and create an account. Secondly, enable your account to authorise Compound’s smart contract to interact with your account. Finally, select the amount of cryptocurrencies you want to lend and issue a transaction to Compound, verify and approve the transaction on your device.

Security features

Ledger Nano S Security Features
Ledger Nano S features 2 hardware chips: ST31H320 & STM32F042

One of the key reasons to buy Ledger hardware wallets is the firms reputation for security. Cryptocurrencies hardware wallets are like bank accounts – they contain full access to funds and need banking grade security. Ledger Nano S contains two hardware chips:

  • Secure Element:  ST31H320 (secure) is independently certified CC EAL5+ and stores the private key and signs transactions
  • Operating system:  STM32F042 chip is responsible for Ledger’s BOLOS proprietary Operating System.

Secure elements are separate pieces of hardware (second layer of security) with their own storage and limited functionality that cannot be breached by hackers.

Even if your computer is hacked or compromised, the Ledger will still keep your cryptocurrencies secure. Devices like the Trezor One and Trezor Model T have chosen not have secure elements and only have a single layer of security.

The Nano X and Nano S are also the only cryptocurrency hardware wallets on the market to received CSPN (First Level Security Certificate) certification issued by the ANSSI (National Agency for Information Systems Security). The certification scheme evaluates multiple aspects of a device’s security including firewall, identification, authentication and embedded software by putting it through multiple attack scenarios.

Similar to the Nano X, users can also protect their funds using a PIN code and passphrase. The PIN code is to generally unlock your device to use it. Whilst you can also set up wallets protected by a passphrase in addition to your primary PIN code.

So say you are threatened to unlock your device, you can give them the PIN code to access wallets with fewer funds. Meanwhile, the bulk of your crypto assets are contained in passphrase protected wallets.

With firmware version 1.6., the security of the Nano S has been further enhanced.

  • Randomised order of digits and symbols for PIN code entry. So other people can no longer guess your PIN code by counting how many times you click the buttons.
  • The device’s operating system chip will be updated by its secure element. Ledger says this will increase the security of the update process and improve user experience.
  • Added screen jitter and partial screen aversion. This update was Ledger’s response to comments that hackers may be able to recover confidential information displayed on the device’s OLED screen by measuring its power consumption. Below are two pictures showing the power consumption of the device before and after the firmware update.
Before the firmware update
Before the firmware update. The power consumption is in a predictable pattern.
After the firmware update. The power consumption is in an unpredictable pattern and the PIN code display is inverted.

Using the device after the update, we find that being unable to enter PIN code digits in order anymore may be prove slightly inconvenient. However with cryptocurrencies, security always comes up top over convenience. And with the added partial screen inversion, we see that Ledger’s bounty program is not just a PR stunt. Ledger actually looked into submissions and made the security improvements even when the suggested hack was only hypothetical.

Ledger hack?

In July 2020, Ledger confirmed they suffered a data breach whereby an unauthorised third party accessed Ledger’s e-commerce and marketing database. As a result, around 1mil email addresses were exposed. Further, 9,500 customers’ had further information exposed such as their first and last names, postal address, phone number and ordered products.

Ledger had reported the matter to authorities and are working with Orange Cyberdefense to investigate.

Subsequent to the data breach, users have been reporting receiving phishing emails and texts by asking them to download a new version of the Ledger software. If users click on the link in the email, they will be redirected to a fake cloned version of the Ledger site. Afterwards, if users download the “update”, which is in fact a malware, it would ask users for their Ledger’s recovery phrase. The entered recovery phrase is then used by the attacker to recover the user’s wallet and send the user’s cryptocurrencies to the attacker’s wallet. For a full explainer on how the phishing attack works see the report from Kraken.

Therefore this incident was a “data breach” rather than a “hack”. More importantly, this breach had no link or impact on the Ledger hardware wallets or the Ledger Live app. Cryptocurrencies stored on the Ledger devices have never been at risk.

Even before the firmware update the Nano S scored full marks on security, and we note that the hack does not affect the Ledger device itself, so our scores remain unchanged.

Multi Currency Support

Supported Coins on Ledger Nano S
Supported Coins on the Ledger Nano S

Ledger has one of the most diverse support for different cryptocurrencies such as NEO, Vechain and Monero. With their open policy to development from project teams, the Ledger Nano S supports 1100+ different assets. Many of these assets like Vechain or NEO are not found on competitors like the Trezor Model T or KeepKey, making Ledger the only hardware wallet available for many coins.

One of the initial weaknesses of the Nano S was that it was only possible to fit 2-3 apps on the device. However the NEW Firmware Version 1.6 released on 13 November 2019, users can now install 5-11 apps (depending on the type of app installed). This will certainly answer the prayers of a lot of average cryptocurrency holders who generally hold around 5-10 different coins.

If you still need more apps, one way around this limitation is to uninstall apps that are not being used and reinstall them in the future. Uninstalling apps will not delete coins – all account information will be retained. The newly released Ledger Nano X fixes this problem by increasing the internal memory to 2 MB.

Ledger’s firmware update directly addressed a significant weakness in the Nano S. Whilst it still can’t beat the Nano X in terms of multi currency support, the update will certainly be good enough for your typical cryptocurrency trader. For this reason, we give our thumbs up and bumped the score up from 4/5 to 4.5/5 for multi currency support.

Hardware Design

Ledger Nano S Screen
Ledger Nano S compared with Nano X

Ledger Nano S has two hardware buttons – located on the top of the device. These two buttons allows us to access menus (hold both buttons), make selections (press both buttons), and even input recovery phrases (use buttons to scroll). We found that entering PINs and recovery phrases to be tedious with only 2 buttons – perhaps a touchscreen or additional buttons could of helped.

With the new update 1.6, the Ledger Nano S has an improved display UI where the full cryptocurrency address is shown without scrolling. This allows for easier verification of the target destination. The Nano S uses a USB micro-B interface for charging and connecting to the PC.

Why use a Hardware Wallet

With traditional currencies, you, the user, are the most important person. If you have ever lost your bank card, you can always go to the bank with some sort of identification and request for access back to your account.

Cryptocurrencies, however, don’t care about the physical person but rather the private key associated with the wallet. The private key is used to verify the account and transactions. Anyone who has access to this key can send funds and that is why you must keep it safe. Another thing is that cryptocurrency transactions cannot be reversed.

Hardware wallets can protect you against these things. They add an extra layer of security by storing the private key on the device itself. The only way to hack it would be to have physical access to the hardware wallet or with the backup phrase.

Ledger Nano S worth it in 2020?

The Ledger Nano S is the most affordable hardware wallet at only USD$59. Even though it’s the least expensive device, it has top of the line security with a CC EAL5+ secure element (military grade security). This device is great for any cryptocurrency HODLer who doesn’t to hold many different assets.

One slight downside of the Nano S is that the new firmware 1.2.4-5 and Ethereum application update (Ethereum 1.6.0) is only available on the Ledger Nano X. These updates will allow users to derive an Ethereum 2.0 public key and validate that the withdrawal public key used in the deposit contract actually belongs to that device.

However the Ledger team are working on integration for Nano S.

Ledger is maintaining its support for the Nano S and showing users that the device is still relevant even with the newer Nano X. Therefore it is clear that Ledger still expects customers to seriously consider the Nano S a device worth getting even in 2020.
