These days I've been looking at LST/re-staking again, honestly, there are only two sources of profit: one is the consensus rewards from basic staking, and the other is selling the "security" again, to give other protocols backing in exchange for points/subsidies/fee sharing or similar. It sounds pretty good, but the risks are quite straightforward: adding another layer means another point of failure, contracts, oracles, governance changing parameters arbitrarily, even redemption queues can block you. Recently, with extreme funding rates, the group is arguing whether to reverse or continue squeezing the bubble. I'm actually more worried that everyone, in pursuit of those extra gains, is pushing liquidity into the same narrow exit... Don't rush, understand the cash flow first.
