Did you even bother to visit the site and learn more about the service before trolling here ? did you even try one f the services that you listed above to know what is the difference between them ?
Yes and yes. I have successfully used spacechain and bitmixer, without any problems. And I don't see anything special in yours except that you mix the coin many times instead of just one or two times, let me know if I missed something else.
I am just informing you of the current "market" , there are lots of mixing services and if yours is not special enough it will never stand up to the ones that have already built up a good reputation. You need some promotions as well, and a few vouches .
