You're being paid 15.3% to absorb price risk. Only ~15.3% of it is real fees — and they stop covering impermanent loss if PRIME-USDC diverges more than the pair moves.
Real fee/staking yield: 15.3% · token emissions: 0% of the headline.
The real fees here (~15.3%) can beat holding if PRIME-USDC stays calm, but a sharp divergence flips that. It's a genuine short-volatility bet, not free income.
