Dormant crypto wallets helped identify alleged Dream Market operator, DOJ says

U.S. authorities say dormant cryptocurrency wallets tied to the now-defunct darknet marketplace Dream Market played a central role in identifying the platform’s suspected main administrator years after the marketplace shut down.

The U.S. Department of Justice announced on 13 May that German citizen Owe Martin Andresen had been indicted on multiple money laundering charges linked to Dream Market, one of the largest darknet marketplaces before its closure in 2019.

German authorities arrested Andresen last week on parallel charges.

According to prosecutors, Andresen allegedly controlled the “Speedstepper” identity, believed to be the main administrator behind Dream Market. 

The marketplace allegedly facilitated large-scale sales of narcotics, counterfeit documents, stolen personal data, and fraud services between 2013 and 2019.

DOJ says dormant wallets exposed key suspect

The indictment alleges that Dream Market’s cryptocurrency infrastructure remained largely untouched after the platform shut down in 2019, including wallets that held millions of dollars in administrator commission payments.

Investigators say activity resumed in late 2022 when funds moved from the original “Dream Wallets” into newly consolidated wallets.

According to the DOJ, those transfers “could only have been initiated by someone with access to Dream Market’s original private keys,” making the wallet activity a critical piece of evidence against Andresen.

Authorities allege Andresen later used some of those funds to purchase gold bars through a cryptocurrency service provider based in Atlanta, Georgia. The gold was reportedly shipped to his home in Germany.

The DOJ said Andresen allegedly laundered more than $2 million between August 2023 and April 2025.

Authorities seized gold bars and crypto-linked funds

German and U.S. law enforcement coordinated raids and searches on 7 May following Andresen’s arrest.

During the operation, investigators reportedly recovered:

• approximately $1.7 million worth of gold bars,
• more than $23,000 in cash,
• and records linked to bank accounts and cryptocurrency wallets containing roughly $1.2 million in suspected proceeds.

Dream Market was one of the most prominent darknet marketplaces following the fall of Silk Road and AlphaBay.

Prosecutors said previous investigations convicted several high-level moderators and administrators, but the alleged main operator had remained unidentified until now.

Blockchain tracing remains central to crypto investigations

The case highlights how blockchain activity can remain visible to investigators long after darknet marketplaces disappear.

Authorities increasingly rely on dormant wallet movements, consolidation patterns, exchange interactions, and off-ramp activity to connect old crypto infrastructure to real-world identities.

The DOJ’s filing also reinforces a broader law enforcement message: even years-old wallet activity can resurface and become evidence in modern crypto investigations.

Final Summary

• The DOJ says dormant Dream Market wallets helped identify the marketplace’s suspected main administrator years after the platform shut down.
• Authorities allege the suspect laundered over $2 million through crypto transfers and gold purchases tied to old marketplace funds.
