Everyone please say, What is the best way to protect a Bitcoin account?
If you're refer to a centralized exchange, you're only can tightening your security with anything offered by the exchange since you say "Bitcoin account"
If you're refer to a non custodial wallet, you're not own an account, but a wallet.
To protect it make sure you're buy a trusted hardware wallet, using a secure PC or laptop, back up your seed phrase in steel plate, using a decentralized exchange, never expose you're holding Bitcoin and learn about privacy.
