Cold wallets use a storage device that looks like a pen drive, and you can store your crypto.
In general, crypto wallets come in two main types: hot and cold wallets. Hot wallets require an internet connection to function, and you can use a specific app to store your crypto. Cold wallets use a storage device that looks like a pen drive, and you can store your crypto. But it also refers to any storage that does not require an internet connection – it can be a physical box, a piece of paper, a hardware wallet, or a list of numbers and letters that you keep in your head. If you opt for a hardware wallet, Ledger Nano X and Nano S are the most popular cold wallets on the market.
