Recently, I've seen people monitoring on-chain large transfers and fluctuations in exchange hot and cold wallets, then interpreting it as "smart money coming/going"... Frankly, you can't see the full picture of others' routes, but you're fully responsible for your signatures.

Those red lines for wallet security should really be avoided: never put your mnemonic phrase into a webpage/form, and don't leave screenshots in your photo album;
When pop-ups ask you to "Approve/Authorize," don't be quick to click—first check exactly who you're giving permissions to and how much, and avoid unlimited permissions if possible;
Phishing sites love to make things "very simple and straightforward," but I see simplicity as a trap.
Anyway, I now prefer to take an extra few seconds, slow down by ten seconds, rather than pay for a moment of impulsiveness.
