While US has declared that all prevailing money laundering laws would apply to bitcoins, China has asked its banks and other financial institutions not to deal in bitcoins and the public has been asked to do so at their own risk.

"The real fear is that Bitcoin can be used to help money laundering," said V Rajendran, advocate and President, Cyber Society of India.
