Since BTC transactions are public you can see where stolen coins are moved. You could use blockchain.info.

With TC container I mean a TrueCrypt container. TrueCrypt is an encryption software, you would then keep your wallet in an encrypted file, that is the TC container. BEWARE you must know exactly what you are doing before playing with Truecrypt.

Mixing Services are used to mix one's funds with others', with the intention of confusing the trail back to the funds' original source. A thief could use one to hide the BTC trail.

Best regards.
