Cold vs Hot: Choosing the wrong Wallet may result in losing coins, this guide can save your life.

Many newbies just put coins in the exchange when they first enter the circle, not realizing that this is playing with fire. Today, let's uncover what a Cold Wallet really is and why experienced users are using it.

How to Protect Your Coins with a Cold Wallet

Your private key is like a bank card password, but there is a fatal difference - it can never be changed. Once leaked, the game is over. A Cold Wallet is a place specifically designed to isolate private keys.

Imagine this: a hot wallet (exchange wallet) is like a convenience store that is open 24 hours, always available but also always at risk of being robbed; a cold wallet is like a safe, not connected to the internet, and no matter how skilled the hacker, they can't touch it.

private key vs public key

• Private Key: A password known only to you, be sure not to disclose it.
• Public Key: An account address that can be shared publicly, allowing others to transfer coins to you.

Store these two items separately: keep the private key in a Cold Wallet and share the public key freely. This is the safe way.

What Types of Cold Wallets Are There

1. Hardware Wallet (most common)

It's like a crypto version of a USB drive. Unplug the network cable, and hackers are powerless.

Trezor Model T ($250)

• Colorful touch screen, the best operating experience
• Supports 1200+ coins and NFTs
• Industry-leading security, but expensive

Ledger Nano X (around $150)

• Cheaper by $100, the security level is the same.
• Supports iOS, but only button operations
• Suitable for people with a limited budget

Disadvantages: Each transaction requires an internet connection, which can be cumbersome, and Newbies may easily get confused.

2. Paper Wallet (Old Antique)

Print out the private key. Since there is no network, theoretically it cannot be hacked. The problem is: if it gets lost, soaked in water, or burned, your coins will be completely gone. It has gradually been phased out.

3. Air Gap Computer

More advanced gameplay, used only by professional miners or large holders.

In simple terms: Are you a coin hoarder? Use a Cold Wallet. Are you a day trader? Use a Hot Wallet + diversify risks.
