Yes, XCY Global LTD appears to be a scam.

XCY Global LTD exploits forex broker templates for fraud, creating identical content and regulatory claims. Despite claiming registration with Financial Crimes Enforcement Network (FINCEN) and the National Futures Association (NFA), no records exist. In addition, the UK Financial Conduct Authority (FCA) issues a warning against XCY Global LTD for unauthorized financial services. 

XCY Global LTD's limited communication options and hidden operator details complicate fund recovery and scam reporting. Traders with XCY Global LTD risk fraud and identity theft. We strongly advise investors to avoid XCY Global LTD and similar unlicensed platforms, opting for strictly supervised ones instead.
