I'm currently in exchanges. But I also need advice on how to store it on hardware wallet. So I'm looking it up now, and purchase one where I know it's good to use.
1. Choose your hardware wallet. Search what's best for you based on feedback, reviews, recommendations of experts. Don't be in a hurry.
2. Buy from their official store/site.
3. After receiving it, dispose your hardware wallet's box/package without exposing it.
4. Set it up. Carefully follow the guide from your hardware wallet's official site.
5. You're probably given only 1 or 2 pieces of where you'd list your seed phrase. Keep more copies. Double, triple, quadruple check them. Make sure you got it right. Your backup is meant to be written on a piece of paper. Don't take pictures. Hide them in different places and locations. If you want, you can buy steel backups.
6. Activate your passphrase option. Make sure your passphrase isn't too short and predictable. Make use of capital and small letters, spaces, numbers, special characters. Write it down on separate pieces of paper and hide them separate from your seed phrase.
7. Do some tests first with small amounts. Make a deposit, make a withdrawal. If you want, wipe your wallet, recover your wallet, and check if your small test funds are still there.
8. Hide your device. It's not meant to be used as a keychain or necklace pendant.
9. Ask questions here.
