This 3.67% is mostly real staking / lending yield (~3.67% of it). No meaningful token emissions. It is single-asset, so there is no impermanent loss to drag you below holding. It can still fall, but it isn't a disappearing subsidy.
Real fee/staking yield: 3.67% · token emissions: 0% of the headline.
No impermanent loss here — the ~3.67% is real income on the very asset you'd be holding anyway. Only any emissions portion fades.
