Answer:
Most companies claim to have the best forex trading system, and some 'guarantee' great profits almost instantly. I would be very wary of any site that is guaranteeing you quick gains as forex is a system that takes time to learn and there are many different strategies you can adopt. I would check out the reviews on a site such as forex trading reviews, where the author gives advice on different systems and tries to identify which are genuinely good systems, such as Everest Forex, and which are just scams.
