It would be better at 0.01 btc rather than 0.10 btc in my opinion
Thanks, we had it previously at 0.01 btc but since we cover network fees (which are crazy high right now) and since we go through at least 6 mixing rounds ( we pay the network fees 6 times) this means that we will be losing money at 0.01 btc, except if we have many mixing orders at once we are barely making any money even at 0.1 BTC.
We hope that the block size issue will be solved ASAP.
Then you should come up with Regressive rate system. More and more amount = less and less fee
So it will make users super comfortable to use and to make decisions based on the fee rate and will profit you as well
