I'm not very good at writing those formal "profit models," but when it comes to LST/re-staking, honestly: returns don't just fall from the sky. Either someone is paying for it (fees, lending spreads, protocol subsidies), or you're taking on more risk. On the surface, it's just interest, but behind the scenes, there may be multiple layers: reducing risks through staking itself, LST de-pegging, smart contract hacks, re-staking using the same security to back other systems... When things go wrong, it's all accounted for together. Recently, memes and celebrities shouting about it are starting to grab attention again. Newcomers get excited and want to "stack more yield," but I really believe in that old saying, "Don't take the last baton." I treat it as high-risk investment now—keep your position small, only play if you understand it, and if you don't, it's okay to just miss out.
