Recently, the debate over re-staking / shared security has flared up again, claiming to be yield stacking. In plain terms, it might also be a "recursive stacking illusion." With my risk-tolerant nature, I get itchy at the mention of "an extra layer of yield," but now I hold back and take a second look: whose contract permissions are involved, whether it can be upgraded at will, and if the fund flow is obvious enough to confuse someone at a glance. Yield stacking is fine, just don't stack risks to the point where they become invisible... And once something goes wrong, everyone will run faster than my confirmation, and Gas fees will also teach you a lesson. Anyway, I treat it like a pressure cooker—survive one day at a time, don't treat it as a savings account.
