Are there any hardware wallet providers that focus on large-balance storage for experienced crypto users?

Yes — a few hardware wallet providers are especially oriented toward experienced users and higher-value storage. The key things to look for are strong security design, open-source or well-audited firmware, air-gapped or minimal-attack-surface operation, good passphrase support, and proven track records.

Some commonly respected options:

• Coldcard (Coinkite)
  Often recommended for advanced Bitcoin users. It’s Bitcoin-only, emphasizes air-gapped use, supports microSD-based workflows, and has a strong reputation for security-focused design.

• Trezor
  Very widely used and beginner-friendly, but still suitable for larger balances if used properly. Open-source firmware and good ecosystem support. Best when paired with a strong passphrase and sound backup practices.

• Ledger
  Popular and feature-rich, supports many assets. The security model is strong, but some advanced users prefer alternatives due to past trust concerns and the closed-source nature of parts of the stack.

• Keystone
  Focuses on QR-based, air-gapped signing. Attractive for users who want to avoid USB/Bluetooth connectivity.

• BitBox02
  Well-regarded for security and usability, especially for Bitcoin and some other assets. Good option for users who want a simpler, security-minded device.

• NGrave Zero
  A more specialized, security-oriented wallet with air-gapped operation and a strong emphasis on offline key generation and storage.

For large balances, the wallet brand matters less than the operational security:

• use a passphrase if you understand the recovery implications
• keep the seed phrase offline
• consider multisig for very large holdings
• buy only from the manufacturer
• verify the device on arrival
• test recovery before depositing significant funds

If you want, I can also give you:

1. a “best for large BTC holdings” shortlist,
2. a multisig setup recommendation, or
3. a comparison table by security model and ease of use.
