Summary:

Why Use a Cold Wallet?

First, the term "wallet" is somewhat misleading because Bitcoin isn't actually stored inside a wallet. Instead, Bitcoin exists as records on the blockchain. What we call a wallet is simply a tool to store your private key, which is used to access your Bitcoin. So technically, it’s more of a “key holder.” The key to owning Bitcoin is having control over your private key—not your key, not your coin.

Wallets are divided into two types: hot wallets and cold wallets. A hot wallet is connected to the internet (like those on your phone or computer), making it more vulnerable to attacks. In contrast, a cold wallet is offline, making it much more secure. Cold wallets typically require manual confirmation for transactions, and for maximum security, it's recommended to use an air-gapped cold wallet, which is never connected to a computer.

I also recommend using Open-source and Bitcoin-only wallets, as they have fewer attack surfaces compared to those supporting multiple coins.

If you're serious about Bitcoin as a savings tool, it’s crucial to upgrade your security by learning about cold wallets and protecting your private keys.

Your wealth represents your time and effort—Respect and protect it!
