About 63% of this 3.93% APY is decaying token emissions. The real fee yield is ~1.45%. It is single-asset, so there is no impermanent loss to drag you below holding.
Real fee/staking yield: 1.45% · token emissions: 63% of the headline.
No impermanent loss here, so you keep the same price exposure either way. The honest number is the ~1.45% of real yield — the rest is fading emissions, not income.
