The leader of Spain's largest cryptocurrency scam FX Winning has been arrested in Dubai, with the amount involved exceeding 460 million euros

According to CriptoNoticias, Spanish citizen David Merino was arrested in Dubai for allegedly leading the cryptocurrency Ponzi scheme FX Winning. This scheme is the largest cryptocurrency-related Ponzi scheme in the history of Spanish investigations, involving over 460 million euros and affecting approximately 15,000 investors. Merino operated the scheme from behind the scenes after officially leaving the company in 2021, attracting funds by promising high returns on forex and cryptocurrency investments. Its operating model involved using funds from new investors to pay early investors, and the scheme operated in about 30 countries.

Spain typically has 15 to 40 days to submit extradition documents to the UAE. Additionally, FX Winning is also under investigation in the United States and Mexico, with the U.S. Drug Enforcement Administration believing the scheme involves 100 billion dollars. Merino released a video in March 2026 denying that he retained others' funds and placing the blame on other members of his team. The Spanish National Securities Market Commission has warned since 2021 that FX Winning is unauthorized to provide investment services.
