Can I use other currency besides USD?

NordFX claims it is owned and operated by NFX CAPITAL VU INC, a company regulated by the Vanuatu Financial Services Commission (VFSC) under license number: 40289. We do find a match result to NordFX in VFSC.

However, VFSC is a popular offshore regulator among forex brokers as capital (or bond) requirements are relatively small. A Forex license covering the online activities of a brokerage is issued in 2-3 months, which is indeed extremely fast. Moreover, there is no income tax, capital gains tax and inheritance tax in the country. So VFSC-regulated brokers are actually not under as strong regulation as FCA, ASIC and NFA regulated brokers. 

Most importantly, some shady brokers will falsely use the regulatory information of a licensed broker by VFSC, as this regulator provides neither authentication details nor domains of the registered company for traders to verify. Consequently, it is not a hundred percent sure that the licensed entity is the one that runs the business under the trading name of NFX CAPITAL VU INC. We would recommend exercising caution when dealing with VFSC- regulated brokers.
