It’s a good point that most protocols have a higher volatility in its early days. Taking cue from your comment, I went back to crunch the numbers from 1st Apr - 26th Apr (26 days) vs previous data of the full 31 days of March. Seems that the transaction fees actually rose, bear in mind the data written as annualised fees for 1st Apr till 26th Apr is technically not annualised since I took 26 days of fees and times it by 12. In fact, the numbers may be much higher.
Back to your point after reducing the ASTRO emissions it via governance, Astroport has a fixed emission of 100mil ASTRO in its first year, therefore a method to reduce its emission is to dilute the emissions from the other LPs to incentivise these Prism Pools. The amount I proposed is 1,374,900 ASTRO out of 100,000,000 ASTRO emissions in the first year. That’s 1.374% of the total first year emissions for 5 LPs for an annualised fees of ~$1.2mil.
