This morning, I tidied up my desk and saw that old charger, and suddenly I thought that the returns from LST/re-staking are pretty much the same: you give others the "electricity" (security/staking verification rights), and they pay you some "electricity fee." To put it simply, the sources are twofold: the underlying staking itself, and the extra subsidies/incentives earned by selling the same security to more services through re-staking.

But the risks are similar to a charger—plugging into too many outlets can cause overheating: first, if the protocol/contract encounters issues; second, when the penalty mechanism on the re-staking side is actually implemented, it might not be just a "small loss" as you imagine; third, liquidity and exit timing—when the market panics, it can get stuck. Recently, everyone has been complaining that on-chain data tools and tagging systems are lagging and might even feed false signals. I, for one, am less willing to just look at dashboards and rush in; I prefer to hard-code my process: small amounts, diversified, and able to withdraw at any time—doing it this way first.
