Greek police arrested 17 people over an alleged cryptocurrency investment scheme that authorities estimate collected more than $8 million from at least 10,000 participants. Investigators say the unlicensed platform promised to double invested capital within 50 days. Two alleged leaders were among those arrested, and a case file was opened against nine additional members. Police identified 18 victims who invested a combined €55,970 and seized €295,090 in cash, along with phones, computers, storage devices, bank cards and other equipment. The arrested individuals were presented to the Prosecutor of the Court of First Instance of Katerini and referred to the Investigating Officer.
