If your funds are tainted, you can then do more laundering and try to remove that association with criminal activity until you have clean coins," he said.Dr Robinson says it is a concerning new trend that could make their work and that of law enforcement harder. But luckily his researchers who tested it say the service isn't working very well at the moment."It actually wasn't very good at identifying links to criminal sites. However, it will inevitably improve over time. So I think this is going to be a significant capability for criminals and money launderers in the future."Governments around the world including in China, the UAE and UK are trying to grapple with the growing problem of money laundering through cryptocurrencies.There have been some high-profile arrests thanks to cryptocurrency tracking - such as US teenager Graham Ivan Clark, who is currently in prison for masterminding one of the biggest-ever social media hacks.<img src="https://ichef.bbci.co.uk/news/976/cpsprodpb/668A/production/_117605262_hackertwittere-1.png" alt="Graham Ivan Clark" class="fr-fic fr-dii fr-draggable " style="" />IMAGE SOURCEHILLSBOROUGH COUNTY SHERIFF'S OFFICEimage captionGraham Ivan Clark was arrested on 30 chargesClark found a way to take over the Twitter accounts of dozens of celebrities, including Kim Kardashian, Elon Musk, Bill Gates and Joe Biden.Clark and his hacker team then tweeted an advert for a cryptocurrency scam, receiving hundreds of transfers from the public hoping to cash in from the fake giveaway.In just a couple of hours Clark made more than $100,000 (£72,000) and began the process of moving the funds around to hide his tracks.It didn't work. In the charge sheet against him, the US Department of Justice said that officers had successfully "analysed the blockchain and de-anonymised Bitcoin transactions allowing for the identification" of the hackers.Clark, now 18, pleaded guilty and is serving three years in a Florida prison.[URL unfurl="true"]https://www.bbc.com/news/technology-58176113[/URL]</blockquote>
