Cinkciarz.pl Founder Arrested in US, Faces €43.6M Fraud Charges and Extradition to Poland

Polish prosecutors charged Marcin P., founder of Cinkciarz.pl, after he was arrested on May 19 near Chicago. The arrest followed an Interpol Red Notice issued in October 2025. Prosecutors accuse him of defrauding more than 7,000 customers, laundering money, and breaching Poland's payment services law. Estimated losses total PLN 185 million, approximately €43.6 million. If convicted, he faces up to 25 years in prison.

Cinkciarz.pl filed for bankruptcy in March 2025 and was approved by a Polish court in October. The online currency exchange was once a leading name in Poland's foreign exchange and payments market before its collapse.
