American law enforcement is adopting new strategies against illegal financial networks, focusing on money brokers using cryptocurrencies for organized crime. This shift reflects the recognition that traditional methods are insufficient in the digital age. Cryptocurrency offers cartels speed, anonymity, and cross-border transactions, complicating tracking efforts. New challenges require innovative approaches combining financial law, cybersecurity, and blockchain analysis. Targeting critical financial flows can significantly disrupt cartel operations, demonstrating the necessity of a comprehensive attack on their infrastructure, including cryptocurrency schemes.
