I just noticed that many newcomers to crypto are confused between hot wallets and cold wallets, so I want to share a bit of experience.

It can be said that a hot wallet is a type of wallet that is always connected to the internet, making transactions quick and easy. It can be an app on your phone like Trust Wallet or MetaMask, or a wallet on your computer, or even a wallet on major exchanges. The advantage of a hot wallet is its convenience — you can send money or receive it instantly without waiting or going through extra steps. But the downside is that it’s more vulnerable to attacks because it’s always online, so if security isn’t strong, there’s a risk of being hacked.

Conversely, a cold wallet is a wallet that is not connected to the internet or only connects when absolutely necessary. This type can be a hardware wallet (Ledger, Trezor), a paper wallet (printing out the seed phrase and keeping it offline), or a dedicated offline computer. The clear advantage is much higher security — it’s difficult to hack remotely since it’s offline. However, transactions are slower and more complicated, requiring multiple confirmation steps.

I often compare it like this: a hot wallet is like cash in your shirt pocket — easy to use but easy to pickpocket if you're not careful. A cold wallet is like a safe at home — much safer, but to access the money, you have to open the safe, which takes more time.

In practice, many people use both types: using hot wallets for daily transactions with small amounts, and storing larger amounts in cold wallets. This method is both convenient and safe.
