You're being paid 10.1% to absorb price risk. Only ~3.68% of it is real fees (the other ~64% is decaying emissions) — and they stop covering impermanent loss if MSUSD-MSETH diverges more than the pair moves.
Real fee/staking yield: 3.68% · token emissions: 64% of the headline.
The real fees here (~3.68%) can beat holding if MSUSD-MSETH stays calm, but a sharp divergence flips that. It's a genuine short-volatility bet, not free income.
