Ledger Nano X Review: Bluetooth Meets Bitcoin Security

What Is Ledger?

Ledger is a French company founded in 2014 that builds hardware wallets for cryptocurrency. They've sold over 6 million devices worldwide, making them the best-selling hardware wallet brand by a wide margin. Their main products are the Nano X (flagship, $149) and the Nano S Plus (budget, $79).

The core idea behind any hardware wallet is simple: keep your private keys offline, away from internet-connected devices where hackers can reach them. When you want to send Bitcoin, the transaction gets signed inside the Ledger device itself. Your keys never touch your computer or phone.

Ledger pairs with its own software called Ledger Live, which runs on desktop (Windows, Mac, Linux) and mobile (iOS, Android). Ledger Live handles the user interface: checking balances, sending and receiving, installing apps for different blockchains. The device itself is the security layer.

With support for over 5,500 coins and tokens, Ledger is designed for the multi-coin crowd. If you hold Bitcoin, Ethereum, Solana, and a handful of DeFi tokens, Ledger handles all of them from one device. If you're Bitcoin-only, that breadth is unnecessary, and you might prefer something more focused.

Nano X vs Nano S Plus

Ledger sells two devices right now. They share the same secure element chip and run the same firmware. The differences come down to connectivity, screen size, and price.

Our take: The Nano S Plus is the better value for most people. Same security, same firmware, $70 less. The Nano X only makes sense if you genuinely need Bluetooth for mobile use. If you're plugging into a desktop anyway, save the money.

Setup and Daily Use

Setting up a Ledger takes about 15 minutes. Here's what the process looks like:

Day-to-day, Ledger Live is genuinely nice to use. The interface is clean, portfolio tracking works well, and managing multiple accounts across chains is smooth. It supports staking, NFT viewing, and DeFi app integrations. For Bitcoin users, most of that is irrelevant, but it's there if you need it.

Security: The Closed-Source Debate

This is the big one. Ledger uses a proprietary secure element chip (the ST33, with CC EAL5+ certification) to store your private keys. It's the same type of chip used in passports and bank cards. Extremely resistant to physical attacks like power analysis, fault injection, and side-channel exploits.

The trade-off? The firmware running on that chip is closed-source. You can't read the code. You can't audit it. You're trusting Ledger to do the right thing. They say the firmware only signs transactions and never exposes your keys. But you can't verify that yourself.

Compare this to Trezor, where every line of code is open-source and auditable by anyone. Or Coldcard, which is also open-source and air-gapped. The Bitcoin community has a strong preference for "don't trust, verify," and Ledger asks you to trust.

Ledger's argument? Secure element chips require closed-source firmware by design. The chip manufacturer (STMicroelectronics) restricts code disclosure as part of the certification process. Ledger says this is a necessary trade-off for physical security that open-source alternatives can't match.

There's merit to both sides. The secure element is genuinely harder to crack physically. But the inability to verify the code creates a trust dependency. For most users, Ledger's track record (no compromised private keys in 10+ years) is enough. For the "verify everything" crowd, it's a dealbreaker.

Ledger Recover: What Actually Happened

In May 2023, Ledger announced Ledger Recover, an optional subscription service ($9.99/month) that backs up your seed phrase to the cloud. The backlash was immediate and intense.

Here's how it works: if you opt in, the device splits your seed into three encrypted fragments. Each fragment goes to a different custodian (Ledger, Coincover, and a third party). To recover, you verify your identity, and the custodians reassemble your seed. It's designed for people who are terrified of losing their seed phrase.

The problem isn't the service itself. It's what it proved. For years, Ledger users believed their seed phrase physically could not leave the device. Recover showed that the firmware has the ability to extract and transmit the seed. Even though it only happens when the user explicitly opts in, the capability existing at all shattered assumptions.

The reality: Ledger Recover is completely optional. If you don't activate it, your seed stays on the device. The firmware update that enabled Recover doesn't change anything for users who don't opt in. But the trust damage was done. Many longtime Ledger fans switched to Trezor or Coldcard after the announcement.

Our recommendation? Skip Ledger Recover. If you're worried about losing your seed, get a steel seed backup for $25 to $50. It'll survive fire, flood, and time. No subscription required.

Pros and Cons

Ledger vs Trezor vs Coldcard

Three different philosophies for the same goal: keeping your Bitcoin safe offline. Here's how they compare:

Bottom line: If you want open-source and the best value, get a Trezor Safe 3. If you need Bluetooth and hold multiple coins, the Ledger Nano X does the job. If you're a hardcore Bitcoiner who wants air-gapped security, the Coldcard is in a class of its own. Check our full hardware wallet comparison for the detailed breakdown.

Who Should Buy a Ledger?

Ledger isn't for everyone. But it's genuinely the right choice for certain users:

• Multi-coin holders. If you own Bitcoin, Ethereum, and other tokens, Ledger's 5,500+ coin support and 100+ app capacity make it the most versatile option.
• Mobile-first users. The Nano X's Bluetooth lets you manage crypto from your phone. No other major hardware wallet does this as well.
• People already in the Ledger ecosystem. If you've used Ledger Live for years and trust the brand, upgrading to a newer model makes sense.
• Beginners who want polish. Ledger Live is one of the friendliest companion apps. The setup wizard holds your hand. The UI is clean.

Who should skip it: Bitcoin-only holders who value open-source. Anyone who was unsettled by the Recover controversy. Security-focused users who want air-gapped signing. For all of these, a Trezor or Coldcard is a better fit.

The Verdict: 7.5 out of 10

The Ledger Nano X is a well-built hardware wallet with the best mobile experience in the market. Ledger Live is polished, multi-coin support is unmatched, and the secure element chip has a proven track record against physical attacks.

But the closed-source firmware is a real issue. The Recover controversy made it worse. And the 2020 data breach showed that Ledger's operational security doesn't match the hardware security. For a Bitcoin-focused audience, these aren't minor quibbles. They go to the heart of what self-custody is about: not trusting third parties.

If you hold multiple coins and want mobile access, Ledger is still the best option. If you're Bitcoin-only, the Trezor Safe 3 gives you open-source transparency at a lower price. That's why we give the Ledger a 7.5 instead of a 9.
