Ledger Nano X
Bluetooth mobile wallet with huge coin support — convenient, but closed-source and controversial with purists.
Overview
The Ledger Nano X is Ledger's mobile-friendly flagship of the Nano line, built around the same certified secure element as its cheaper siblings but adding Bluetooth and a rechargeable battery. That combination lets you manage a Bitcoin and multi-coin portfolio from your phone through the Ledger Live app without a cable, which is genuinely convenient for people who send on the go.
Under the hood it works like any hardware wallet: private keys are held inside the secure element, and every transaction is signed on-device and confirmed on its screen. The Bluetooth link only carries already-signed data and public information — your keys never travel over it — but Bluetooth does widen the attack surface compared to a wired-only device. You can disable Bluetooth and use USB-C if you prefer.
The Nano X supports thousands of coins and has large app storage. The honest downsides are the familiar Ledger ones: closed-source firmware, the controversy around the opt-in Ledger Recover service, and a battery that degrades over years (your keys are safe regardless, since the seed is what matters). If you want open-source firmware, consider a Trezor Safe 5 or BitBox02; if you want full air-gap, look at a Coldcard or Keystone.

Ledger Nano X: frequently asked questions
Is Bluetooth on the Nano X a security risk?
Your private keys never leave the secure element and are never transmitted over Bluetooth; only signed transactions and public data are. Still, wireless adds attack surface, so use USB-C if you want the smallest surface.
Why do some Bitcoiners dislike Ledger?
Mainly the closed-source firmware and the 2023 Ledger Recover announcement, which showed the device can export an encrypted seed if you opt in. Critics prefer wallets whose firmware they can fully audit.
What happens if the battery dies?
Your bitcoin lives on the blockchain, secured by your seed phrase — not inside the device. A dead battery just means you restore your seed onto a new wallet.
Is the Nano X worth the extra money over the S Plus?
Only if you specifically want Bluetooth and mobile untethered use. The security and coin support are otherwise comparable.
