What is a cold storage crypto wallet?

A cold storage crypto wallet is an offline wallet that is never connected to the internet or any other network. This provides security against remote hacking attacks as there is no way for a hacker to electronically access your wallet or steal your private keys without having physical access to the storage medium.

Some examples of cold storage crypto wallet include hardware wallets like Trezor or Ledger, paper wallets, and even offline computer storage or external hard drives. The main aspect they all share in common is complete disconnection from the internet or any network.

This is contrasted against hot wallets which are software or hosted web-based wallets that remain connected online. Though convenient for transacting, they lack the enhanced security benefits of offline cold storage crypto wallet. Hence, savvy cryptocurrency investors often utilize both hot and cold wallets in tandem.

Benefits of cold storage crypto wallets

There are several excellent reasons why you should consider utilizing a cold storage crypto wallet for a portion of your cryptocurrency holdings:

- Extremely Secure Against Remote Hacking Attacks: The main benefit is enhanced security against hacking attacks since cold wallets remain completely offline. Even if a hacker breaches an exchange and attempts to drain your cryptocurrency holdings, your cold storage crypto wallet funds remain inaccessible to them.

- Full Control of Assets/Private Keys: With cold storage crypto wallet, you retain full control and possession of your cryptocurrency private keys. There's no third-party reliance like web wallets. Only you have access to the private keys needed to sign transactions.

- Long-term Storage for Investment Holdings: Cold wallets are ideal for long-term portfolio holdings for investment or savings purposes since they are disconnected from the volatility of the market. You don't need to worry about constantly trading or transacting these funds.

- Geographic Mobility: With a hardware wallet like a USB drive or paper wallet, you can physically carry your cold storage crypto wallet anywhere on your person or store it in a safe location like a safe deposit box. This makes it handy for travel while knowing your holdings are still safe.

Types of cold storage crypto wallets

There are several ways you can implement a cold storage crypto wallet:

Hardware Wallets

Perhaps the most popular implementation is purchasing an offline hardware wallet device:

- Ledger

- Trezor

- KeepKey

These operate as a special secure USB flash drive device engineered specifically for securely storing cryptocurrency private keys offline while still enabling you to conduct transactions. They have a small display screen to visually verify and confirm transactions with manual buttons. Hardware wallets start at around $50 USD.

Paper Wallets

As the name suggests, a paper wallet involves printing out your cryptocurrency private and public keys in QR code form on a piece of paper:

- Creating paper wallets is free as it only requires a printer.

- However, generating paper wallets securely can be more technically challenging.

- durability issues with ink fading, rips, moisture, etc

Offline Computers

You can also dedicate an old computer or laptop for a complete cold storage crypto wallet. It should be wiped completely clean and never connected to the internet again. Though this forms an air gap from the internet, it still leaves more vulnerabilities than a hardware wallet solution.

Setting Up and Using a Cold Storage Wallet

The first step is to acquire your preferred cold storage crypto wallet medium, whether a hardware wallet or generating paper wallets. If going the hardware wallet route, purchase a recommended brand device like a Ledger Nano S or Trezor.

Next, you'll generate your wallet addresses and private key backups. Be sure to create the cold wallet completely offline and store any backup recovery phrases or data securely in an offline format. Never digitally transmit or take a photo of sensitive wallet recovery details. Physically writing down on paper is most secure.

To add cryptocurrency funds to your cold storage crypto wallet, you'd start by initiating a send transaction from your regular online hot wallet or exchange account to the receiving public wallet address of your offline cold storage crypto wallet.

When ready to sign outgoing transactions from your cold storage crypto wallet, you'd manually connect your cold storage crypto wallet temporarily to an internet-enabled device, verify the transaction details, sign it manually with your private keys, and then disconnect again once completed. This keeps exposure of the cold wallet to the internet to a bare minimum.

Security Tips for Cold Storage

Here are some key security best practices for maximizing protection of your offline cryptocurrency cold storage:

- Generate private keys and recovery phrases completely offline, not just on a different machine

- Physically write or etch recovery phrases into stainless steel plates to withstand moisture, fire, etc

- Pick obscure locations away from prying eyes to stash steel plates or paper wallets

- Use a BIP39 passphrase along with a recovery phrase for added security

- Enable any available PIN code and built-in encryption on hardware wallets

- Purchase hardware wallet directly from the manufacturer instead of Amazon, eBay, etc

By rigorously following security best practices, your offline cryptocurrency holdings will have unmatched protection against online hacking attacks. Just be sure your heirs know how to access the wallets if anything happens to you!
