Frequently Asked Questions

Which hardware wallet is the most secure?

All major hardware wallets (Ledger, Trezor, Tangem) offer excellent security. Ledger uses a secure element chip, Trezor is fully open-source, and Tangem offers card-based security. Choose based on your specific security preferences.

What's the difference between Ledger and Trezor?

Ledger uses a secure element chip and supports more cryptocurrencies, while Trezor is fully open-source and offers better transparency. Ledger has a smaller form factor, while Trezor has a larger screen.

Are hardware wallets worth the cost?

Yes, hardware wallets are essential for securing significant cryptocurrency holdings. They protect against online threats, malware, and exchange hacks. The cost ($50-$ 200) is minimal compared to the potential losses from security breaches.

Can hardware wallets be hacked?

While no device is 100% secure, hardware wallets are extremely difficult to hack. They keep private keys offline and require physical access, as well as a PIN/passphrase. Follow best practices, such as buying directly from manufacturers and using strong PINs.

What happens if I lose my hardware wallet?

If you have your seed phrase backup, you can recover all your cryptocurrencies on a new device. This is why secure backup storage is crucial. Without the seed phrase, funds are permanently lost.

How many cryptocurrencies can I store?

Hardware wallets can store hundreds to thousands of different cryptocurrencies. Ledger supports over 5,500 devices, Trezor supports over 1,800 devices, and Tangem supports over 6,000 devices. Check specific coin support before purchasing.
