To find out best method of protection, we can try to remember when the last time we were hacked or scammed. And what has lead to it. I was hacked once, and I think it was done due to me being unexperienced. Fund were stolen from my wallet. And I still cant remember what exactly I did and how it happened. Either I have connected wallet to a scam page or gave access. Or when trying to receive reward (it was when bounties were popular), instead of copy/pasting wallet address, I have copy/pasted private key. All that happened 6 years ago. Since then nothing happened.
