A 
recent report from the joint Bitcoin analysis team of FDD and Ellicit, a Bitcoin forensics company, indicates that less than one percent of all Bitcoin transactions involve money laundering.
The report, written to help analyze the flow of funds and the danger of money laundering, has indicated that money laundering isn’t nearly the problem some critics of cryptocurrency believe. The report states:
“The amount of observed Bitcoin laundering [is] small and darknet marketplaces such as Silk Road and, later, AlphaBay are [generally] the source of almost all of the illicit Bitcoins laundered through conversion services.”
The report also indicates that the vast majority of illicit transactions using Bitcoin were processed in Europe, receiving more than five times as many illicit transactions as North America
