Best Practice #1: 2FA, You Know?
Turn on that 2-factor authentication, mates. It's like a digital bouncer at your Bitcoin club. Keep the riff-raff out!
This suggests using centralized services in first place like exchanges and custodial wallets that have a 2FA option. Using these services is discouraged to begin with...
Tool #2: Browser Shields
For our non-native pals, browser shields like MetaMask can help spot scammy sites. They're like your online bodyguards, savvy?
Apart from the fact that MetaMask is an altcoin wallet not a "shield"; technically you should keep your bitcoin offline so that getting your online system infected wouldn't affect them. And if you want protection install uBlock Origin and a decent Anti Virus on your system that has net protection.
