Recently, someone asked me again, "That APY on the yield aggregator looks pretty attractive, should I buy?"

I usually first check the contract and who the money is actually lent to: some split your funds into multiple parts, and if the underlying protocol has an issue, it can lead to a chain reaction;
there are also counterparties that are actually just a market-making/lending pool, claiming "auto-compounding," but basically betting that others won't withdraw first.
No matter how attractive the APY numbers are, they can't hide the fact that a contract might have a single permission or upgrade point that isn't clearly written.

Recently, Meme and celebrity shoutouts have also drawn a lot of attention, and I agree with veteran players advising newcomers not to take the last step.
The same applies to yield products: when it's hot, everyone thinks it's "safe"; when things cool down, you realize there's just a door.
Anyway, I’ve written in my logs: if I don’t understand the fund flow or know the liquidation/pause conditions, I just cross it out.

A colleague also said a couple of days ago, "Why do you always focus on risk?"
I can't really explain, and if my reaction is slow, I can only rely on rules to survive, so that's how it is for now.
