Perhaps being careful is not just enough but also educating ourselves with the right knowledge regarding scams, phishing links etc is very important hence to protect us a little bit more as the internet itself is not a safe place.
I agree with that. But you cannot deny that being careful is most important. For example, I knew how these phishing scams work. But I was careless one night, and I was scrolling through social media, and I suddenly received an email. I was kind of sleepy and saw the email was from an airdrop hub website, and the email said I had some unclaimed reward. I went ahead without checking the sender of that email and connected my metamask wallet. It takes less than 30 seconds to wipe out my entire wallet. I realized right after signing, but that was too late already. I revoked the connection but the wallet was drained already. It's not like I didn't know how these scams works. It happened because I was careless.
