Beyond Hardware Wallets: 5 Alternative Ways to Secure Your Bitcoin

Hardware wallets have long been considered one of the recommended ways to protect Bitcoin, as they keep access keys away from devices constantly connected to the internet. However, security incidents involving Ledger wallets and recent concerns regarding Coldcard wallets have brought back the debate over whether even supposedly secure storage solutions can fail. Here are five alternatives, each with its own advantages and disadvantages.

1. Bitcoin ETFs

Instead of holding coins directly, investors can buy an exchange-traded fund that holds Bitcoin through a financial institution or custodian. This eliminates the need to manage private keys and back up wallets independently. However, the investor holds a security rather than Bitcoin that can be transferred directly on the blockchain. Furthermore, they depend on the fund manager and asset custodians, while paying management fees.

2. Passkey-Based Wallets

Digital access keys, known as passkeys, allow users to authenticate via biometric tools like fingerprint recognition, facial scanning, or PIN codes. Solutions like Coinbase Smart Wallet, Clave, and Infinex make crypto usage simpler and reduce reliance on long recovery seed phrases. Nonetheless, users must carefully check how to recover access if a device is lost or a passkey is compromised.

3. Multisig Wallets

This method requires multiple keys to authorize transactions. For example, in a two-of-three setup, three entities hold keys, but any two must sign off on a transfer. This minimizes the risk that the theft or loss of a single key leads to a total loss of funds. Services like Casa offer such solutions, but managing multiple keys can be complex and requires robust security.

4. Crypto Exchanges

Leaving coins on an exchange transfers the responsibility of key management to the operating company. This suits active traders and those prioritizing convenience, but users remain exposed to exchange solvency, security standards, and withdrawal restrictions. Proof of reserves does not fully guarantee a platform's ability to meet obligations.

5. Paper Wallets

Private keys and wallet addresses can be written down on paper without dedicated hardware. However, generating keys in an insecure environment risks exposure, and the physical paper can be damaged, stolen, or lost. Therefore, while offline, it is not inherently safer.

The ultimate takeaway is that no storage solution is flawless. Diversifying assets across various methods helps reduce risk, but requires careful planning and comprehension of who controls the keys.
