Bitcoin wallet safety: the basics

Your seed phrase is your wallet. Whoever holds it controls the bitcoin. Three rules: 1. Generate the seed on a trusted device — preferably a hardware wallet. 2. Back it up offline, in at least two physically separate places. Steel plates beat paper. 3. Never type it into a website, photograph it, or store it in cloud notes. For larger amounts, look into multi-signature wallets (multi-sig). A 2-of-3 setup means a thief needs to compromise two different devices in two different places.
