This document compares hot and cold cryptocurrency wallets. Hot wallets are connected to the internet and allow sending and receiving tokens but are less secure since private keys are stored online and vulnerable to hacking. Cold wallets have no internet connection, storing private keys offline for enhanced security, making them suitable for long-term investors. The best cold wallets are Ledger Nano X, Ledger Nano S, and Trezor T due to their security features like offline private key storage and confirmation buttons.
