Recently, I came across the concepts of re-staking and shared security again, and everyone is arguing whether "yield stacking is just a Ponzi scheme."

As a spot trader who swings, I find it quite tempting, but a second of calm made me realize: where does the yield come from?
Essentially, someone is paying for security/incentives, or new projects are throwing subsidies to keep you in the pool;
adding an extra layer of tickets on-chain, money doesn't just multiply out of thin air.
The risks are pretty straightforward: contract/bridge/custody issues are one layer, if the underlying gets fined or rules change, that's another layer,
liquidity gets stuck and can't be sold, which is yet another layer...
In short, it's like the "invisible tail" keeps getting longer and longer as you stack more layers.
A couple of days ago, I almost FOMOed in, but then I lowered my expectations: just want some extra pocket money, not a salary.
It actually felt more relaxed, at least I can sleep well.
