Monkey make an exchange where you can change bitcoins for litecoins and all the others. Just among the crypto currencies and not bother doing the cash in and out crap. Make it so that on a single exchange multiple transactions happen behind the scene, one bitcoin to litecoin then to feathercoin and on and on, a dozen, hundred, thousand times. I dunno, enough to obfuscate the history of the coins. Sending the end transaction to a brand new wallet. It'd be like a pass service, the more passes they want the more "cleaner" it gets. Deviant minds would find that service useful. Regular simpletons could just do a simple currency exchange into some other coin. All digital for you, would only need to acquire your base of coins to make the magic happen.
I may be out of my element here, I'm drinking hot coco and it was 90 degrees at 8 in the morning and am watching the Sunrisers of Hyderabad.
I would do it and HQ it out of Venezuela, but, you know, coding and shit.
