Forex is derived from "Foreign Currency Exchange". This is the process of changing one currency into another. The foreign exchange market is where currencies are traded. Trading currencies can be risky and complex and requires expertise to make money from it. As this is a lucrative venture, scammers pose as fake broker or gurus, purporting to give people tips or help people trade.
It is important to do an independent research on anyone or company claiming to be a broker so that you don't fall victim to this scam.
