Might be shift in customer from bitmixer to chipmixer have increased the amount of donation they are getting from few big users.
After bitmixer closure volume went up and donations went up but support requests went up (customers were used to simpler mixing process) and donation percentage went down (customers were used to automatic fee deduction).We are thinking about adding ChipMixerLite version that would work exactly like old BitMixer - you send output addresses, receive signed contract, send coins and wait a few hours to get them. The good part would be simplicity. The bad part would be split of mixers volume and less privacy. What do you think about it?
Honestly i don't think it's a good idea.
Chipmixer is a brand by itself and is the first to use private keys directly as a mixing tool to achieve 100% anonymity. Having a chipmixerlite will only confuse users, and probably create a split between the pathways to take which is not good.
I would consider adding a minimum fee instead of donation because as you said a lot of people from Bitmixer are used to having a mandatory fee charged alongside with their mixing process. After all you do need to pay for the transaction fees when you transfer funds into individual chips, pay for server, support, and advertising costs.
