$450K Bitcoin Romance Scam: Following the Blockchain to a Mixing Service

Background

Over 8 months, a victim was manipulated through a sophisticated romance scam into sending a total of $450,000 in Bitcoin. The scammer claimed to be a U.S. military officer stationed overseas. When the victim realized the deception, they engaged TraxinteL.

Investigation Methodology

1. Transaction Graph Analysis: All 23 Bitcoin transactions from the victim were mapped, revealing a complex web of receiving wallets, intermediate hops, and consolidation points.
2. Mixer Analysis: Approximately $270,000 was routed through a known Bitcoin mixing service. We applied time-volume correlation analysis to trace funds exiting the mixer.
3. Scam Network Mapping: The receiving wallet cluster was compared against known scam wallet databases and linked to other reported victims.

Key Findings

• The scam operation received funds from at least 14 other victims, with total proceeds estimated at $2.8M.
• Despite the mixing service, 60% of the victim's funds ($270,000) were traced to withdrawal wallets on two regulated exchanges in Southeast Asia.
• The scammer's "military officer" persona was recycled across at least 6 different romance scams on different platforms.

Outcome

A comprehensive blockchain forensics report was delivered to the FBI's IC3 and the victim's attorney. Exchange cooperation requests were filed in two jurisdictions. Estimated recovery viability: Moderate.
