What would be a popular mixer with plenty of volume?
https://bitmixer.io/FULL OBSCURITY FOR THE PEOPLE! jokes, I bet the mixers keep records.
If you are that paranoid, go through 2 different mixers.
It is double the fee, but the chance that they are in cohoots is very low
Just learning the ropes at the moment, interested in how DarkWallet is going to fair in the up and coming months

last time i checked zero coin was in better position than darkwallet, because it was based onf zero-knowledge proof
i would simply use monero for now, if i want to avoid tracking, you sell monero for goods here on bitcointalk, i'm sure there are those who can accept it, it's pretty stable as a currency
Had a glance at ZeroCoin but never really gone any further.
How would it be possible to track back to the origin source if the transactions were mixed, broken down and distributed across random intervals- all to different addresses?
Magic. IT would be very difficult to tell and maybe even impossible in some cases but it all depends on how well they're mixed.
It would be impossible in all cases unless the mixer sites store information on the customers as they don't forward payments but mix with other payments and the original will have no connection with the final one.
Thanks for rounding the point up. My thoughts exactly bud
