Good practices Holding your coins on an exchange, even a reputable one, even with 2FA enabled, is risky. Someone could impersonate you and steal your funds within minutes, while you are sleeping. The exchange could get hacked. You will not get your coins back if that happens. Get yourself a Trezor or Nano Ledger S. A hardware wallet allows you securely receive and perform crypto-currency transactions even on a malware-infested computer.
Make sure to buy your hardware wallet from an official source. Do not use the hardwaret wallet if it comes with a scratch-off card!! Properly securing that passphrase is the most important step of the setup. This is the passphrase that you will stamp onto a plate of metal to preserve it for decades to come.
Losing or destroying your hardware wallet would not affect you in any way, as long as you safeguard that recovery seed, you will still have access to your funds. You must be the only person to see your recovery seed. Do not ask someone else to stamp it into metal for you.
NEVER enter your recovery seed into any electronic device, file, website, or even bip39 bitcoin exchange rates password manager. The recovery seed will be shown to you ONCE on the screen of your hardware wallet, but never leaves its memory. You may write it down on paper temporarily in a private location, until you have a chance to secure the materials for stamping on metal. Do this before you send large amounts of funds to the hardware wallet.
And repeat this every time you duplicate your recovery bip39 bitcoin exchange rates onto a new medium. Why you must test your recovery seed before sending large amount of funds Recovery Seed storage By default, the 24 word recovery seed is the only thing required to access private keys. This means it can survive even a sustained, severe house fire.

Properly securing and storing your recovery seed is much more important than securing your hardware wallet. In fact you should treat your hardware wallet as a disposable, fragile device which can be lost, destroyed, or wiped out any time, but can be replaced with a small amount of money.
Your recovery seed cannot bip39 bitcoin exchange rates replaced. Given the risk profile of my geographical location, I rate this probability as low.
