With the sending of Bitcoin back and fort the only thing that you will accomplish is you loose some coins along the way because of the fee's and charges while you can always use a mixer like Bitmixer and if you are not satisfied and still in doubt you can use another mixer like Bitblender I think that will break any link you.
