Recently, I've seen a bunch of people promoting LST/re-staking for "an extra layer of yield," and honestly, the returns are not falling from the sky: either someone is paying (through lending, market making, derivatives counterparties), or you're taking on more risk (being penalized or confiscated, contract upgrades, nodes/intermediaries causing trouble, liquidity being drained and unsellable). Don't treat "stacked yields" as a printing press; it's more like repeatedly using the same collateral to generate invoices.

By the way, the funding rates are extreme, and the community is still arguing whether to reverse or continue squeezing the bubble... I just want to say: when the rates are high, the so-called "extra yield" you see is often just a premium for crowded trading, and it can turn against you quickly if market sentiment shifts. Anyway, whenever I see any "yield stacking," I first ask: who bears the losses/penalties/liquidations, and make the timestamps clear before discussing further.
