About 10% fee:
Many times we have lost and frozen our own funds due to users sending high risk funds. Questions about these transactions appear after we complete orders. You can't even imagine how much money was lost due to users like this one. This is our rule. If some user does not agree with our rules, he can use another exchanger.
Since the user did not provide any evidence of using ChipMixer, we have every reason to believe that the funds were stolen. Refusal to provide additional information confirms this. Many times, such freezes allowed the thieves to be stopped and the funds returned to the rightful owners.
there are many illogicalities here.
You hold 10% of user funds to protect your own. now there is obviously no danger to your funds and you return the remaining 10% to the user.
would you have returned it even if this drama had not happened on Bitcointalk?
how will you behave in the next similar cases? Returning 100% depends on your frozen funds or if a negative story is started about your business (like this one)?
why are there even cases where you kept 10% of such funds, although, in the end, it turned out that it had no negative impact on your accounts?
