While cryptocurrency has plenty of legitimate uses, it has been identified as a payment method in transactions involving illegal drugs, firearms, explosives, human trafficking, child sex and child pornography.
Although cryptocurrency is a global phenomenon, it has real local impacts. If you are in an area that has seen a spike in opioids deaths recently, you also have a cryptocurrency problem as well. A couple of notable cases are Peter the Great and Aaron Shamo. Both of these involved cryptocurrencies as the means of payment for massive amounts of fake opioid pills that were actually fentanyl tablets.
But narcotics are just one incidence of illicit cryptocurrency use. Another concern for law enforcement and the financial sector is the peer-to-peer cryptocurrency trader. This person advertises themselves as a person willing to exchange real currency for cryptocurrency or vice versa outside the traditional financial system, which requires real names and reporting of activities.
If there is money to be made, the criminal element will be the first to exploit new technology. This was true of cryptocurrencies, and law enforcement is just now catching up and beginning to assign real identities to cryptocurrency transactions. Today, law enforcement can use software to track and trace bitcoin transactions and give them the leads they need to follow the money trail.
The peer to peer exchanger most often is acting as a money launderer for dark web activities. In theory, a buyer and seller can anonymously exchange goods for money by using a dead drop , but either party to the transaction could lie in wait for the other. Law enforcement might also be able to determine the location of a dead drop and arrest both participants.
Therefore, dark market vendors are moving to cryptocurrency as a means of payment for all types of illicit goods. People become anonymous by using software to connect through multiple computers so that no one knows where they are actually sitting, operating on the dark web see below , using encrypted communications and by conducting transactions via cryptocurrency.
They further their anonymous activities by seeking out and using peer-to-peer cryptocurrency exchanges to transfer from fiat money to cryptocurrency and back again. Think of the internet as a smart phone map where you enter the name of a place like Amazon. Once you are on the dark web, you could have accessed sites such as Alphabay, Silk Road 1 and 2 and Valhalla Market, which offered a whole new world of illicit commodities until they were shut down by law enforcement.
It is important to understand that sites on the dark web only can be shut down if law enforcement determines that they do exist and where they are located. But like any criminal enterprise, new suppliers pop up to take the place of any which go dark. It is a game of cat and mouse using some of the most advanced technology on the planet. But there are ways to find ghosts lurking on the dark web.
What appears to be anonymous at first glance might not really be anonymous at all. Blockchain Intelligence Group has created a suite of solutions to trace bitcoin transactions, giving law enforcement the tools they need to follow the money trail. From this point, the law enforcement officer can get a warrant to force the exchange to divulge the real identity of the account owner. Some uses of cryptocurrency are perfectly legal, even if morally questionable, and these legitimate users of cryptocurrency have little to fear.
However, for bad actors using cryptocurrency, Blockchain Intelligence Group is the new sheriff in town. While it may be impossible to use a single clue to solve a crime, a handful of clues might help you nail your suspects. For example, you have one suspect that you are pretty sure of, but you think he had an accomplice. You know that he goes to one of the same three restaurants every week for two months, and witnesses can pick him out, but no one else.
Now you have a suspicious pattern that needs to be looked at.
