By 2015, BTC-e was reportedly facilitating just over 3 percent of the worldwide daily volume of cryptocurrency trading. But, according to some sources, the company was also facilitating up to 70 percent of worldwide criminal activity involving cryptocurrencies. Washington alleges that the company was built on a model that relied heavily on the activities of criminal entities, as the latter sought the ability to conduct online monetary transactions without being tracked by governments.

In 2017, American authorities seized BTC-e’s website —a move that terminated the company’s operations. Washington also prompted authorities in Greece to arrest Vinnik, while he was vacationing at a Greek resort with his family. The Russian co-founder of BTC-e is today in a Greek prison, awaiting a decision by the Greek authorities to extradite him to the United States. If this happens, he will be tried on 21 counts of international money laundering and a host of other criminal charges.

Interestingly, however, shortly after Vinnik’s arrest, the Russian government filed a court order to have Greece extradite him to Russia, where he is reportedly wanted for relatively minor fraud-related charges. What is more, the Greek government was directly lobbied by no other than the Russian President Vladimir Putin —an unusually high-level approach, when one considers Vinnik’s trivial charges in Russia. France has also sought to have Vinnik extradited there, instead of the United States.

What lies behind these moves? There are many who believe that American authorities moved against BTC-e after realizing that Russian spies used the company to hide their traces while trying to meddle with the 2016 presidential elections in the United States. A recent report by the State Department’s RFE/RL news website claims that a number of London-based observers from groups such as Global Witness and Elliptic Enterprises believe there are strong links between Russian spy agencies and BTC-e. American authorities have managed to access information about the inner workings of BTC-e’s website. They are probably viewing Vinnik as an intelligence asset, who can potentially shed light on the company’s alleged role as a money laundering mechanism for Russian spies —and probably others as well.
