@Lohoris There's good info there but everyone is focusing on securing a single transaction not the coin history and more broadly exchanging coins to other currencies. Example: If a government sees a coin go to a known "bad" address then to an exchange. They can then subpoena the exchange and the "bad" person is caught.

This is true, but likely criminals would find ways of laundering like they do with conventional fiat currencies - something like shared send (https://blockchain.info/wallet/send-shared) comes to mind.

@GeorgePearce Great link, I'm frustrated that kind of anonymity isn't built in but glad to know about that
