It might be worthy to add that 'only' using TOR doesn't obscure everything enough to never be found/tracked.
While using the TOR browser does help a lot, the privacy also highly depends on the user.
Can someone please tell me why bitcoin mixers seem typically seem to have both a darknet and clearnet address? Maybe I'm missing something obvious, but just now I can't imagine what the point is.
The whole point is privacy.
Thats also the same reason why some mixing services (eg. ChipMixer) do offer a non-java script mixing service. Reducing the graphical animation, increasing the privacy.
