&gt;And if you mix enough coins you can decrease the chances of being pinpointed exactly as the source, but you cannot definitively remove yourself from the bucket of suspects.<p>Not in my understanding. I have some coins X that are tainted. I send them to you, Y. You, Y, happen to have other coins completely unrelated to the address I sent my X coins to, and you send them to me at address Z. There&#x27;s no blockchain link between X and Z.<p>I suppose physically tracking you down, assuming you keep logs, could hurt me, but if I trust you not to keep logs then I&#x27;m safe after you delete the logs.
