"Hey Bro, I'm about to download a crypto wallet but I'm confused with Hot Wallets vs. Cold Wallets. What's that Bro?"
Bro, think about the difference between the Leather Wallet in your back pocket and a Steel Safe bolted to the floor in your basement.
The Wallet in your pocket is for spending. It's fast, easy to grab, and perfect for buying coffee. But if you walk down a dark alley, you might get mugged.
The Steel Safe is for saving. It takes ten minutes to open, but even if robbers break into your house, they probably can't get into it.
That Pocket Wallet is a Hot Wallet.
That Steel Safe is a Cold Wallet.
The terms "Hot" and "Cold" just refer to the Internet Connection.
