What does the fact that I'm wearing a signature with MixTum has to do with me recommending people to not use exchanges as mixers as they aren't designed for that?
In my understanding people who wear signature associated with a specific entity are essentially endorsing the services offered by that entity. MixTum openly acknowledges its utilization of coins from exchanges to deliver mixed coins to its clients. However, it appears that you hold a stance against incorporating exchanges into the mixing process started by individual saying exchanges are not mixers. It appears that you primarily care about the signboard but not a result.
