Keep it secret. Keep it safe.
— Good Advice
If you follow the instructions on this page, you'll have better security than most Bitcoin holders. Your Bitcoin will be secure. And if anything goes wrong, you'll know how to recover it.
Five easy steps:
1. Buy a hardware wallet direct from the manufacturer. Not sure which to get? You can't go wrong with a Trezor. Trezors are easy to use and open source. Never use a hardware wallet that isn't open source. Bitcoin is open source. Your hardware wallet should be, too.
2. Let the hardware wallet generate a random seed phrase for you. The words are used as entropy to generate a unique Bitcoin wallet.
3. Write your seed phrase on paper. This is the backup of your wallet. Make a metal backup, in case the paper gets damaged. Never type the words on your computer or phone, no matter what. Never type your words in an app, no matter what. This keeps you safe from hackers.
4. Store the paper and metal backups of your seed phrase somewhere only you have access to. A thief can't use your seed phrase to rob you if the thief can't find it.
5. 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 from scratch 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. Hooray!
P.S. Don't tell anyone you own Bitcoin. Keeping it secret helps keep it safe.
Hodl!
