You're being paid 0.28% to absorb price risk. Only ~0.28% of it is real fees — and they stop covering impermanent loss if USD₮0-USDC.E diverges more than the pair moves.
Real fee/staking yield: 0.28% · token emissions: 0% of the headline.
The real fees here (~0.28%) can beat holding if USD₮0-USDC.E stays calm, but a sharp divergence flips that. It's a genuine short-volatility bet, not free income.
