In the fast-evolving world of cryptocurrency, securing your digital assets is no longer optional—it's essential. The Ledger Nano X (Onyx Black) stands out as one of the most trusted hardware wallets on the market, offering robust security, expanded storage, and seamless integration with mobile and desktop platforms. Designed for both beginners and experienced crypto holders, this compact device provides peace of mind by keeping private keys offline while still enabling convenient access to manage and grow your portfolio.
Whether you're holding Bitcoin, Ethereum, or a diverse range of altcoins, the Ledger Nano X delivers a secure environment for transactions, staking, and long-term storage.
🔐 Advanced Security for Your Crypto Holdings
At its core, the Ledger Nano X is built around security-first principles. It uses a Secure Element chip—a technology trusted in banking and government systems—to protect your private keys from online threats. Even if your computer or smartphone is compromised, your crypto remains safe because the private keys never leave the device.
Every transaction must be manually confirmed on the device using two physical buttons, preventing unauthorized transfers. Additionally, a 4- to 6-digit PIN code locks the device; without it, even someone who steals your wallet can’t access your funds.
"Your Ledger cannot be used without first entering a 4-6 digit PIN, so even if someone steals it, it’s useless if they can’t get past the PIN."
This combination of offline storage, hardware-based encryption, and user-controlled verification makes the Ledger Nano X one of the safest ways to store cryptocurrency.

💾 High Storage Capacity for Diverse Cryptocurrencies
One of the standout upgrades from the Ledger Nano S is its enhanced storage capacity. With enough space to install up to 100 apps, users can manage a wide variety of cryptocurrencies—from mainstream assets like BTC, ETH, XRP, and XLM—to niche tokens supported through third-party integrations.
Unlike software wallets that limit accessibility based on platform support, the Ledger Nano X allows you to add different crypto “apps” via the Ledger Live desktop or mobile application. This modular approach means you’re not locked into a fixed list—you can download only the coins you need.
"It stores mainly the mainstream coins like ETH, BTC, XRP, XLM, or any big traders on exchanges."
For long-term investors managing multiple assets, this flexibility eliminates the need to juggle several devices or worry about running out of space.
📱 Bluetooth Connectivity: On-the-Go Crypto Management
The inclusion of Bluetooth functionality sets the Ledger Nano X apart from its predecessor. Paired with the Ledger Live app on iOS or Android, users can securely manage their crypto from a smartphone without needing a USB cable.
This feature is particularly useful for checking balances, initiating transactions, or engaging in staking while traveling. Many users report smooth pairing with Apple devices like the iPhone 15 Pro, noting that connection within a one-foot range works reliably.
However, feedback on Bluetooth performance is mixed. While some praise its convenience, others have encountered issues such as:
- Failure to pair with certain Android models
- Inconsistent connectivity during transaction signing
- Requirement for close proximity between device and phone
Despite these challenges, Bluetooth remains a valuable tool for mobile-centric users who want flexibility without sacrificing security.
⚙️ Setup and Usability: Intuitive but Requires Attention
Setting up the Ledger Nano X typically takes between 20 to 30 minutes for tech-savvy users. The process involves:
- Connecting the device to a computer or charger
- Installing firmware updates
- Creating a 24-word recovery phrase (critical for asset recovery)
- Setting a secure PIN
While many find the interface straightforward—especially those familiar with tech gadgets—others report frustration due to the repetitive button navigation required across the small monochrome screen. Unlike touchscreen competitors, every menu action requires multiple clicks.
Additionally, the screen automatically locks after 10 minutes of inactivity (adjustable), requiring frequent PIN re-entry. Though this enhances security, it may feel cumbersome during extended use.
"Using the actual device isn't too difficult, you have 2 buttons that scroll through lists."
Still, once configured, daily operations run smoothly for most users.
🔋 Battery Life Concerns: A Notable Drawback
One of the most frequently cited issues is battery degradation. Numerous customers report that their Ledger Nano X units eventually stop charging or fail to power on altogether.
Key concerns include:
- Devices arriving with low battery (e.g., 34% charge)
- Rapid battery drain during active use
- Complete failure after months of regular use
- No option for battery replacement due to sealed design
"Now the bad. From the start I had the dreaded battery problem."
Since there’s no replaceable battery, hardware failure could result in permanent loss of access unless proper backup procedures were followed. This underscores the importance of securely storing your 24-word recovery phrase, which allows you to restore assets on another Ledger device or compatible wallet.
💰 Value for Money: Premium Features at a Premium Price
Priced higher than entry-level options like the Ledger Nano S, the Nano X justifies its cost with added features: larger storage, Bluetooth, and improved build quality. Most users agree it’s worth the investment—especially for those holding significant crypto value.
"The Ledger is the only way to keep your crypto safe. It's a great little device that stores your crypto without worrying if it will go under or disappear into thin air."
That said, some consider it overpriced given reported hardware flaws and lack of future-proofing (e.g., non-replaceable battery). For users prioritizing longevity and simplicity, a non-battery model with expanded storage might be preferable.
