Recently, someone was talking about LST and re-staking again, asking me "where does the profit come from." Basically, there are two parts: one is you repackage the original staking rewards and continue selling liquidity; the other is re-staking to rent out "security" as a commodity, and when others want to use your collateral, they give you a subsidy. But once the sentiment cools down, that subsidy can turn into "everyone wants to run first." The risks are pretty straightforward: the more layers stacked on the chain, the more serious the problem if something goes wrong — it’s not just a skin-deep fall, but the whole system cramping up. I now avoid cross-chain bridge hacks at a glance, and when oracles report abnormal prices and everyone shouts "wait for confirmation," it’s not without reason. When a real mistake happens, you won’t even have time to manually stop it. Anyway, I now have one rule: don’t chase hype, don’t leverage, and accept lower returns so I can sleep peacefully.
