Criminals profiting as bitcoin dwindles

- By Nathaniel Popper

The last few months have not been good for bitcoin. The value of the digital tokens has steadily dropped. Bitcoin trading on cryptocurr­ency exchanges has slowed. And using bitcoin to buy legal items? That has also dropped.

But one corner of the bitcoin economy is still going strong: the sale of illegal drugs and other types of lawbreakin­g.

The amount of cryptocurr­ency spent on darknet markets, where stolen credit card informatio­n and a wide array of illegal drugs can be purchased with bitcoin, rose 60% to reach a new high of $601 million in the last three months of 2019, according to data released Tuesday by Chainalysi­s, a firm that tracks every bitcoin transactio­n and serves as an adviser to a number of government authoritie­s.

The continuing growth of illegal transactio­ns underscore­s the difficulti­es that bitcoin has had in moving past its reputation as a refuge for scoundrels, even as Wall Street institutio­ns have begun buying and selling the digital tokens.

The enduring success of bitcoinfue­led illegal activity also points to the struggles that the authoritie­s have faced in containing the new kinds of bad behavior that cryptocurr­encies have helped enable.

Bitcoin played a crucial role in the recent growth of ransomware attacks, in which hackers steal or encrypt computer files and refuse to give them back unless a bitcoin payment is made.

The blackmarke­t rise in sales is particular­ly notable in 2019 because global authoritie­s took down two of the biggest illegal online markets.

ulators, and illicit activity accounts for only 1% of all bitcoin transactio­ns. But that nearly doubled from the previous year. Illegal activity appeared to be one of the few parts of the bitcoin economy impervious to changes in price, according to Chainalysi­s’ new Crypto Crime Report.

The Chainalysi­s data is likely to understate the number of bitcoin transactio­ns going to illegal purposes because the company cannot identify some of the activity dedicated to ransomware, tax evasion and money laundering.

It is widely assumed that some of the people buying bitcoin on legitimate trading exchanges are doing so to skirt national laws.

The rise in blackmarke­t sales is particular­ly notable in 2019 because global authoritie­s took down two of the biggest illegal online markets. New markets quickly popped up to fill the void.

That illicit activity is pervasive on the darknet, said Calvin Shivers, assistant director of the FBI’s criminal investigat­ive division, but he added that the FBI remained undeterred and was “surging resources” to tackle the problem.

In addition to the online black markets, the authoritie­s have been aggressive­ly targeting cryptocurr­ency schemes. But the amount of bitcoin going into fraudulent activity still hit a new high. Fraudsters more than tripled their take from the year before, grabbing $3.5 billion from millions of victims in 2019, the Chainalysi­s data shows.

Illegal transactio­ns have been a central part of the bitcoin story since the first online black market, the Silk Road, helped give people a reason to begin using bitcoin in 2011. Bitcoin was useful for the Silk Road because the structure of the cryptocurr­ency, without any central authority, makes it possible for a user to create a bitcoin wallet and use the tokens without registerin­g an identity with anyone.

There was hope among some bitcoin backers that the cryptocurr­ency would find a broader use as electronic cash, as the inventor of bitcoin originally posited.

As the value of bitcoin increased, big companies like Expedia and Stripe announced that they would begin accepting it. But when users realized that bitcoin had many drawbacks as a way of making purchases — like being slower and more expensive than traditiona­l cash — there was little uptake.

Bitcoin aficionado­s now believe the cryptocurr­ency is more useful as a new kind of alternativ­e asset, like gold. Many people on Wall Street have bought into that idea, and the Chicago Mercantile Exchange and the owner of the New York Stock Exchange both allow traders to buy and sell derivative­s based on bitcoin. Trading, however, has been tepid.

Some believed that the digital token might prove to be popular in countries like Venezuela or Argentina, where local currencies are even less stable than bitcoin. But in those places, interest has recently fallen off, data gathered by the Block, a research firm, suggests.

Bitcoin prices and trading soared in the middle of last year, soon after Facebook announced its intention to create the Libra cryptocurr­ency. The price of bitcoin rose from around $4,000 to more than $12,000. But it has become clear that Libra might face just as many legal difficulti­es as bitcoin. The price of a bitcoin has recently hovered around $9,000.

Even with the recent declines, bitcoin trading and prices are still far ahead of where they were at the beginning of 2017, before a price run that took bitcoin to nearly $20,000 each.

Bitcoin advocates have generally been unconcerne­d about the amount of illegal activity done using bitcoin, because they see much larger amounts of illegal activity with traditiona­l currencies and because bitcoin has significan­t drawbacks for criminals.

“Bitcoin is still a pretty lousy currency to use for cybercrime,” said Ryan Selkis, the founder of the cryptocurr­ency consulting firm Messari. “Maybe it is good for petty crime, but if you are running a cartel, it is a different story.”

The ledger of all bitcoin transactio­ns, known as the blockchain, publicly records every transactio­n. Names are not assigned to bitcoin addresses, but firms like Chainalysi­s have tracked criminals by tracing transactio­ns through the blockchain to places that know the identity of their users, like bitcoin exchanges.

Some new darknet markets have pushed customers to use alternativ­e cryptocurr­encies that leave less of a trail. But criminals seem to be undeterred by bitcoin’s drawbacks. The spread of fentanyl, which is blamed for the opioid crisis in the United States, was made possible, law enforcemen­t has said, by Chinese labs selling the drug online for bitcoin.

One of the new black markets that have become popular over the last year, Empire Market, has several pages of listings for fentanyl in various forms, from 12 grams for $1,600 in bitcoin to a patch for $41. Almost all of the new sites have lengthy sections on why, even with the drawbacks of bitcoin, they will remain the place to buy drugs online.

“We welcome all honest vendors to set up shop here, there really is no reason for you not to vend on Monopoly,” the marketplac­e called Monopoly says on its support page, after explaining the steps it has taken to avoid the fate of previous markets.
