Recently, I've seen a bunch of projects talking about "yield stacking" and shared security again.

I'm actually quite easily tempted, but I'm also afraid that what I'm stacking isn't actually returns, but illusions...
To put it plainly, if you repeatedly use the same collateral to back different positions, essentially you're also compounding the risk: confiscation, smart contract vulnerabilities, validation/node operation errors, some tricks on the bridge side, which could propagate layer by layer, ultimately leading to bigger losses.

And now there's still chatter about interest rate cuts, the dollar index moving up and down with risk assets, and when emotions run high, people are more willing to believe "it will go up anyway."
At such times, I tend to cut the expectations in half and first clarify the exit path and costs.

If I could only keep one habit: before each interaction, write a sentence about the worst-case scenario.
