Argentine Prosecutors Arrest 24, Seize Over $8M in USDT in 'Fake Coins' Crypto-Fraud Sweep
Argentina's Buenos Aires Public Prosecutor's Office executed 90 coordinated raids, arresting 24 individuals and freezing more than 8 million USDT—roughly $8 million—in what officials call the province's largest crypto‑seizure. The operation also uncovered nearly 60 million pesos in cash (about $48,000) and 80 mobile phones, and it dismantled three distinct fraud rings targeting retail investors, WhatsApp hijacks, and a Chinese‑origin infostealer scheme. Prosecutors estimate the total economic damage at almost 3 billion pesos, roughly $2.4 million, across more than 100 complaints. The bust underscores the challenges Argentina faces in regulating a rapidly expanding, largely unregistered crypto‑advisory market.
