why don't you use a mixing service like bitmixer?
Why not get a darkcoin wallet then use shapeshift.io to turn your bitcoins to darkcoins and then back to bitcoin, they will be completely mixed and no one can track them back to you.
I agree that the darkcoin switch is a good way to go.
Have you tried
https://poloniex.com/ ?
You could lend out some coin for margin traders and then pull it back in with profit and send out.
poloniex requires your personal information to let you withdraw from your account, and that defeats the purpose of OP.
you can use bittrex instead, i think the number of confirmation isn't high and it requires only the standard fee of 10,000 satoshi. with no need to any personal information. it has 2fa too.
Yeah, bittrex is you're best option if you do not want to give any personal information out. It is your choice but some sites offer lower fees in exchange for little person information.
