Investment fraud causes substantial financial losses in Greece, with the HCMC maintaining one of the most active warning registers of any European regulator relative to national GDP. Social media advertising — particularly Facebook and YouTube — drives victims toward unlicensed brokers offering Forex trading, crypto funds and real-estate crowdfunding with guaranteed returns.
The HCMC investor education division reports that Greek victims are particularly targeted with real-estate-linked investment products, given the cultural and historical importance of property ownership in Greece, as well as with crypto products promising recovery of savings lost during the Greek financial crisis.
How this scam works on Greece
Facebook ads featuring photographs of well-known Greek landmarks or celebrities direct victims to platforms offering 'guaranteed' 8–25% annual returns on Forex or crypto funds. A broker calls the victim in fluent Greek and walks them through creating an account and making an initial deposit.
The platform displays impressive returns. The broker builds a regular calling relationship, encouraging escalating deposits. When withdrawal is eventually attempted, a request appears for a 'φόρος υπεραξίας' (capital gains tax) or a 'πιστοποιητικό HCMC' (HCMC certificate) that must be paid before funds are released.
In some Greek cases, fraudulent real-estate crowdfunding platforms collect investment in undeveloped Greek island properties, combining property ownership aspirations with crypto-era investment language to attract victims.
