Isn't it sufficient to transfer from your wallet => any exchange => a second wallet you own (where no one knows the addresses belong to you)?
Now it's only you and the exchange that knows the second wallet belongs to you. If you registered with a false name, not even the exchange knows.
Am I right?
deposit them into an exchange and then withdraw. you end up with different coins, as exchanges act like a mixer. and the better part is you dont have to touch legally dodgy sites like silk road.
other options are to swap it for litecoins. and take those litecoins out and then use the litecoins on another exchange to convert back to bitcoins
Both of the above are correct. I find it funny seeing people chasing a thief through the block chain. The thief kept using mixers but even then, he was still relatively easy to chase.
If the thief were to simply use an exchange that doesn't use ID Verification, the outgoing coins should be unrelated.
