A Kenyan man is among six Africa-based suspects charged in the United States over an alleged cryptocurrency investment scam run from scam compounds in Madagascar. Nicodemus Hingima Monyancha is accused of working with Cameroonian national Gislen Neukeu, Ugandan national Shamusa Ninsiima, Rwandan nationals Clement Mugiraneza and Merveille Macacumura, and Chinese national Chui Kok Wa, identified by prosecutors as the alleged leader. US prosecutors said the case is part of a broader crackdown on cryptocurrency and online investment fraud linked to transnational criminal networks, targeting people through fraudulent NFT investment platforms. Authorities allege scammers posed as attractive women on dating websites and used social media and messaging apps to build relationships with victims before pushing them to invest. Once victims connected their cryptocurrency wallets to fake websites, they were reportedly encouraged to deposit more funds that the scammers allegedly stole. FBI investigators identified about 74 cryptocurrency wallets tied to roughly 800 US victims who reported losses after dealing with the fraudulent platforms. Court affidavits say the group set up scam compounds in Madagascar in early 2025, moving operations from Cambodia after law enforcement action there. Investigators also traced stolen funds to cryptocurrency accounts associated with Wa. Prosecutors say Wa’s phones contained employment contracts showing workers in Madagascar operated overnight shifts aligned with daytime and evening hours in the US. The devices allegedly included scripts instructing workers on emotionally manipulating victims to secure investments, including language describing the scheme as an “emotional scam.” The charging documents also point to staff rosters listing names, passport details, salaries, working hours, disciplinary records, and cryptocurrency wallet addresses. The case follows an FBI-supported operation in Madagascar in August 2026, when authorities dismantled 13 suspected scam compounds and seized more than 3,200 electronic devices. The US later faced difficulties interviewing people linked to the case after Madagascar repatriated many suspects to China. The defendants are charged in the US, and investigations are ongoing as prosecutors seek to identify more participants, trace cryptocurrency, and pursue alleged perpetrators.
