Recently, I saw a bunch of people talking about LST and re-staking again, honestly, the returns are just a few types: the basic interest from underlying staking, plus subsidies that projects give out to attract TVL (this part is the most volatile), and then there's lending out the same "security/reputation" to collect rent. It sounds great, but the risks mostly come from these areas: subsidies stopping causing yields to collapse, contract issues/oracle failures, de-pegging causing panic, and the most annoying part — thinking you're earning steady interest when in fact you're just relying on others' willingness to keep paying you.

I'm still slowly picking up the cheap deals myself, preferring lower yields so I can understand better "who's paying, why they're paying, and for how long." Recently, there's been a heated debate in the community about privacy coins/mixing and compliance boundaries, which is somewhat similar to re-staking: if the rules change, the previously normal cash flow might suddenly become invalid... Anyway, don't get too caught up, better to stay steady.
