Hot wallet vs hardware wallet

• A hot wallet is an app on your phone (MetaMask, Trust Wallet). Quick and easy for trading, but only as safe as your phone, because it's online.
• A hardware wallet is a small device that keeps your keys offline. You confirm every transaction on the device, so a hacked phone or computer can't sign for you.

A simple rule: a hot wallet for trading money, a hardware wallet for savings you won't touch. Either way, your 12 words are the master key. Keep them offline.
