I use Kraken where the maker fee is 0.12% and the taker fee is 0.22%

I don't think there are any reputable exchanges with extremely low fees.

The exchange would need huge volume to be able to be profitable at a lower fee, and the volumes just arn't there anymore. Lots of exchanges expanded in the 2017/2018 spike, and then the volumes fell away, leaving them with a lot of staff and fixed costs and falling revenue.
