however if you know of a miner who is willing to trade your coin for his fresh mined coin. you obtaining fresh mined coin without the fluff of mixer rounded mount tagging is better for you
Why should on earth any miner accept your dirty coins and give you their fresh mined coins? What's the benefit for the miner? Well, if you give them the double money, then they might think about it but otherwise, I think no miner will accept such an offer.
Some mixer claim they offer option to give their customer freshly mined coin. IIRC the fee is around 4% - 10%. So if they're not lying about it, i can see some miner would work together with mixer.
