If you follow the instructions on this page, you'll have better security than most Bitcoiners. Your Bitcoin will be secure. And if anything goes wrong, you'll know how to recover it.
Seven easy steps.
1. Buy a hardware wallet direct from the manufacturer. Not sure which to get? You can't go wrong with a Trezor.
2. While setting up your wallet, write down everything you do, so you'll know how to do it again.
3. Let the hardware wallet generate a random seed phrase for you. The words represent numbers that generate your Bitcoin wallet.
4. Write your seed phrase on paper. This is the backup of your wallet. Never type the words on your computer or phone, no matter what. Make a metal backup, in case the paper gets damaged.
5. Store the paper and metal backups of your seed phrase somewhere only you have access to. A thief can't use it to rob you if the thief can't find it.
6. Before sending Bitcoin to a new wallet, save a copy of the wallet's first address on your computer or phone. Then wipe out the wallet and restore it using the seed phrase you wrote down. If you got the same first address, you proved you know how to restore your wallet if anything goes wrong.
7. Don't tell anyone you own Bitcoin. Keeping it secret helps keep it safe.
Hodl!
