Key Takeaways
• Cold wallets keep private keys offline, secured by hardware, offering unmatched safety for long-term crypto storage.
• OneKey Pro combines 4x EAL6+ secure chips, fingerprint auth, wireless charging, and SignGuard parsing for advanced protection.
• OneKey Classic 1S is fully open-source and affordable—great for storing BTC/ETH securely over years.
• Tangem and BitBox offer compact form but lack screens or deep interaction, making them risky for large or long-term storage.
• Ledger Stax is feature-rich but closed-source; Trezor Safe 5 is open-source but more basic—each with pros and cons.
• A great long-term wallet isn’t just secure—it must offer verifiable backups, open firmware, and sustainable support over time.
As the crypto market continues to mature, more and more users are realizing that long-term holding of cryptocurrencies is the most reliable investment strategy.
However, ensuring asset security over many years—avoiding risks such as hot wallet breaches or exchange hacks—requires a stronger safeguard: the cold wallet (hardware wallet).
By keeping private keys offline and protected by secure chips, cold wallets isolate your assets from online threats. For investors who don’t seek frequent trading but instead value security, stability, and longevity, choosing a reliable cold wallet is like adding an insurance lock to your wealth.

Equipped with a large color touchscreen, fingerprint authentication, and wireless charging, OneKey Pro balances strong security with usability. With multiple EAL6+ chips and SignGuard parsing, it ensures your BTC and ETH remain secure over many years. - OneKey Classic 1S
A cost-effective choice for long-term cold storage. Fully open-source with EAL6+ chip protection, making it an excellent option for securely holding BTC and ETH for years to come. - Ledger Stax
Feature-rich with strong branding, but closed-source design and higher price limit its appeal for those focused solely on long-term storage. - Trezor Safe 5
Known for transparency and open-source design, but its transaction parsing and multi-chain usability fall behind OneKey. Better for those who want basic long-term storage with auditability. - Ellipal Titan 2.0

Swiss-made, simple and compact, supporting BTC/ETH. Small screen limits user interaction, but solid for straightforward long-term storage. - Tangem
Card-style wallet, very portable. However, the lack of a screen makes it unsuitable for high-value long-term storage—better used for backups or smaller holdings.
