Recently, I was again browsing the "High APY" page of yield aggregators, and honestly, those numbers are like the signboards at the entrance of an archive, whether they are lit or not doesn't mean there are no traps inside.

Clicking in to take a look, it's often not a single strategy, but layered with multiple contract authorizations, lending pools, re-staking, and other counterparties, any one of which going wrong could turn the yield into a story.
Now sharing security and yield stacking are being criticized as "nested dolls," which I can also understand— the more layers, the less it relies on the market, and more on everyone just not running away first.
Last night, I also experienced a withdrawal that required refreshing and retrying, waiting in line for a long time, and immediately my mindset became clear: whether I can make a profit is secondary, I first need to think about the worst-case scenario— can I sleep well?
Anyway, I now prefer to keep it a bit lower and the structure clearer.
