Cause that mean examples i send btc to As address and your systems will mix that address so no one can know As address right?
Send BTC from address A to mixer's address B
A -> B
Mixer does his trick and sends the coins from one of his addresses C to your final address D.
A (you) -> B (mixer)
C (mixer) -> D (you)
Now there is no link between A and D. Now if the mixer in specific is effective, we can't really assure.

Ohh I SEE. THAT'S LOOK THIS PROJECT IS VERY PROMISING. KEEP WAITING WHAT THEY PLAN TO DO.
