Darknet markets are increasingly returning to bitcoin (BTC) as their primary cryptocurrency

After major exchanges delisted XMR, we observed a significant increase in bitcoin inflows, according to Eric Jardine, cybercrime research lead at Chainalysis.

Darknet markets are increasingly returning to bitcoin (BTC) as their main cryptocurrency due to rising liquidity and accessibility challenges associated with privacy-focused coins like monero (XMR), according to Chainalysis.

This shift follows the delisting of XMR by major crypto exchanges, which has decreased the coin's accessibility and liquidity.

"After major exchanges delisted XMR, we observed a significant increase in bitcoin inflows as a result, and reduced accessibility is steering users back toward bitcoin," said Eric Jardine, cybercrime research lead at Chainalysis, in an interview with CoinDesk.

Many Western markets on the darknet - a part of the internet hosted within an encrypted network and accessible only through specialized anonymity-providing tools - had either fully moved to monero or operated with it in parallel with bitcoin before the delistings. XMR dropped off after it was removed from major exchanges.

OKX removed XMR and other privacy-focused tokens including dash (DASH) and ZCash (ZCH) at the end of 2023. Binance announced in February that it planned to de-list monero.

"In order for a coin or token to be listed on Binance, it must meet our internal listing standards and the requirements of the industry at the time of listing," Binance said.

"When a coin or token no longer meets this standard, or the industry changes, we conduct a more in-depth review and potentially delist it."

On-chain data from BitInfoCharts shows that the daily number of monero transactions has halved from this time last year.

"In order to be an effective kind of medium of exchange, you need a certain amount of liquidity and a certain amount of accessibility," Jardine said.

Jardine emphasized that illicit cryptocurrency transactions represent only a minor share of total crypto activity.

"Typically, illicit transactions constitute or below 1% of total crypto activities. While addressing these issues is essential, broadly labeling crypto negatively is inaccurate and counterproductive."

Chainalysis data shows that about 0.14% of all transactions in crypto, some $50 billion, involve illicit activity, with a rise in stablecoins as an illicit payment mechanism.

The stablecoin issuers are fighting back, with the Tron-led T3 Financial Crime Unit, a group comprising of Tron, USDT-issuer Tether and TRM Labs freezing over $100 million in illict funds.

Jardine also noted that law-enforcement agencies prioritize darknet markets primarily based on their size and involvement in the fentanyl trade.

Its presence significantly escalates the likelihood of a darknet market attracting attention from law enforcement, as fighting the drug is a priority for international authorities.

"Markets have sort of varying levels of sensitivity to fentanyl-related sales," he said.

"Some claim they don't do it, then don't police vendors; some claim they don't do it, but then they do. Some will be selling precursor products but not finished products."

Indeed, one of the most recent darknet market busts was the Nemesis online market. The U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) specifically cited the market’s role in the fentanyl trade as a reason for the bust.

And, as a result, OFAC sanctioned a number of crypto wallets tied to its operator, Behrouz Parsarad: 44 BTC addresses and 5 XMR wallets.
