Cryptocurrency enthusiasts were pleased to hear that their long-held belief that Bitcoin’s main use is not, in fact, for illicit activity is true. This is according to a new report from the US Drug Enforcement Agency (DEA) who spoke to Bloomberg about Bitcoin’s illicit use cases.

DEA special agent Lilita Infante explained to Bloomberg that their research concluded that the ratio of legal to illegal activity has flipped in recent years to due to the mainstream adoption Bitcoin has seen. Infante explained that she initially saw the use of Bitcoin in cases she was investigating five years ago, and that her analysis of blockchain data showed that about 90% of Bitcoin’s transactions were related to criminal activity. Since that data was collected five years ago, Infante now claims that illegal activity has shrunk to about 10%, mainly due to speculative investments.

Infante’s special task force focuses on dark web and virtual-currency related crimes, and frequently collaborates with other departments including the FBI and the ATF. She explained the results of her task force’s analysis, saying:

“The volume has grown tremendously, the amount of transactions and the dollar value has grown tremendously over the years in criminal activity, but the ratio has decreased…The majority of transactions are used for price speculation.”

Most people with little understanding of cryptocurrencies associate the technologies with anonymous transactions on sites like Silk Road and other underground websites. This perception has been vocalized by Bitcoin’s critics, including US congressmen like Representative Emanuel Cleaver.

Following reports from the US Justice Department that Russia had used Bitcoin to purchase the domains used to post leaks from the hacked DNC servers, Representative Cleaver was the first one to blame Bitcoin, saying in a tweet:

“I’ve been warning about the potential dangers of Bitcoin being used by nefarious actors. Now, we know Russia used cryptocurrency to fund their meddling campaign in 2016. The crypto industry needs to step their game up.”

Many Bitcoin proponents commented on this tweet, asking the Representative why he doesn’t blame the US dollar for being the choice currency for things like drug purchases, human trafficking, and illegal weapons sales.

It is important to note that the public nature of Bitcoin’s blockchain works to the advantage of law enforcement, as it allows them to track patterns and connect cryptocurrency wallets to specific individuals.
