First we take a look at the total fees collected Curve Finance. Curve hit ATH in mid May 2020 with over 400K USD of fees collected in one week and went downhill from there to 50K per week. Recently (September onwards), we saw gradual increase in fees collected.

If the fees collected denominated in ETH, we saw steep downtrend from March 2021 until July, and the value sideways from there.

Total number of unique active users has been declining since early last year to this year to date.

But for ankETH, the fees collected peaked in first few weeks and gradually decreasing but in September, it caught second wind and increased.
