barusan liat thread ann bestmixer, agak ironi setelah ngeliat judul awal thread mereka waktu pertama kali di buat Truly Anonymous Bitcoin Mixer!
-snip-
Padahal kalo berdasarkan informasi yang ada di ANN, best mixer menjanjikan bahwa pengguna tetap akan berstatus anonim dan rekam jejak 'order' bakal dihapus setelah 24 jam

We remove your order history completely and automatically in 24 hours after the execution of all mixing conditions
Kenapa bisa demikian... Mungkin om bisa melihat/mempelajarinya dari hasil thesis karya Felix Maduakor pada berikut ini:

...
The most important conclusion of my work is, that even though a mixing service/a mixing algorithm might seem to be reliable at the moment, through a single leak/implementation fault, an attacker could be able to deanonymize any past transaction which has been processed by the mixing services. Even though the leak/implementation fault gets fixed by the service, every transaction which has been processed prior to the fix is irreversible vulnerable.

bitmixer.io & coinmixer.se are offline now, however its still possible to use the bugs I describe in my thesis to reverse nearly all transactions which have ever been processed by these services.
In my thesis, I attacked coinmixer.se (at the time of writing it was the biggest centralized mixing service), however - except chipmixer.com1 - every other centralized mixing service I checked could be broken in a similar fashion.
...
1 Chipmixer was the only centralized mixing service which I did not break fully. However, I did not put much work into checking this mixing service.
