I've been googling and trying to figure out how to be anonymous dealing with BitCoins. What I've learned is that I some how have to break the chain of transactions.
Are mixers/tumblers out of date? Is there anything I'm missing? All the threads and info I find on the subject is over a month old, which is kinda old for BitCoin if you ask me. Maybe I'm wrong?

Consider the following scenario:
I have a web shop that sell services for BitCoins. When I cash out I don't want Mt.Gox or whatever exchange I use to be able to trace the money to the buyer of my service nor the shop.

How would I do that? Or is it not possible right now?

Im sorry if the question has been asked and answered somewhere else. If so, just point me in the right direction please.
All I can find is out dated answers that doesn't explain how to do it today.

Ps. To those who will go down the line with "don't do anything illegal and you don't have to be anonymous". It's not about that. I have my reasons why I want to be anonymous and that's the end of that.
