...MixTum itself will not need to spend too much money when operating, From there, it is possible to reduce transaction fees from 0.0007 to lower fees.
The
"problem" with your idea is that at any moment the fees can change drastically, and it is difficult for any service to automatically react to such changes, and therefore they set some kind of fixed fee that serves as a protective mechanism.
MixTum also needs income and profits to maintain its service, and users who really need it will worry too much about transaction fees. As I estimated in the table, when the amount of BTC needed to be mixed is over 1 BTC, the fee will return to nearly 5%.
Such a fee may seem too high compared to other mixers, but MixTum has (as far as I know) a unique mixing method, which consists in the fact that the user does not receive coins that are the product of mixing coins that arrive in the mixer, but they are BTC that come directly from various CEXs. In this way, a much higher level of privacy is obtained, and then it must have a slightly higher price.
I can also confirm that the mixer is down, we hope it's just regular maintenance, and this has happened in the past, so for now we have to wait until the situation is resolved.
