I see you've been bragging about those 10 btc in escrow, but let's see if it DOES actually make sense: assuming you are a new market player and so have a relatively small amount of customers, your cap of simultaneously mixed coins is 100 btc (for simplicity) and that's where exit scam happens (for whatever reason, we are just assuming here). And let's say there were 100 people where everyone was mixing a single coin, which means that if the escrow will be WILLING to collaborate and allocate funds proportionally then everyone gets 0.1 btc.

Does only for me this thing look ridiculous and proves absolutely nothing? Keep in mind that we have an optimistic 1 to 10 ratio here (escrow/mixer), so if the real turnover is higher than you'll probably get like a few satoshis or so from the escrow.

Good luck with establishing trust but imo this is not the right way of doing it.
