We investigate opportunities and limitations of anti-money laundering (AML) in Bitcoin, a decentralized cryptographic currency proliferating on the Internet. We analyze several services offering increased transaction anonymization that have emerged in the Bitcoin ecosystem -- Bitcoin Fog, BitLaundry, and the Send Shared functionality of Blockchain.info. In a series of experiments, we use reverse-engineering methods to understand the mode of operation and try to trace anonymized transactions back to our probe accounts. While Bitcoin Fog and Blockchain.info successfully anonymize our transactions, we can link the input and output transactions of BitLaundry.
