As cryptocurrencies enter the lives of the ordinary people cybercriminals start using them to facilitate crime. Europol last year estimated that about 3-4% of crime proceeds are laundered through the use of cryptocurrencies and that this figure is rising steadily. There are two main reasons - lack of regulation and anonymity. Recently, Anderson et al. showed that it is both computationally and legally possible to follow the 'taint' that a stolen coin leaves as it propagates through the network. In this paper we present new visualisation mechanisms for taint propagation in Bitcoin that display how cyber criminals launder money.
