I am with @Asu. We need dedicated DEX-swapping-marketing in order to 10x the trading volume in mid term, in order to reduce the rewards and move the ROI to be created through the actual business model.
A draft proposal I made a few days ago, can be found here.
That said, the rewards and inflation scheme is not per se bad. It allows the expansion of the ecosystem. It’s just to much and takes too much importance. Its a marketing tool to attract LPs, in my eye (could be interpreted as cost, rather than the profit in that sense).
