Its easy to same and its not to some. But what is easy and what is not? A person who likes to cook say its easy to cook. A person who does not like to cook say its hard to cook.Actually it's not, but some people may say that it is perhaps each one of us has their own point of view regarding this matter because we may earn easily in here, but we can also equally lose easily in here so when you earn today, and you will lose at the next day you will end up with no profit at all.
In short if you want to trade then its easy to learn but if you don't have intention to learn how to trade then its hard. Because in my part I really don't think its hard to learn in forex. What you only need is commitment. Learning in forex is in your own time. You can study forex when ever you have free time and so on. But if you really don't give time to learn forex then I'm sure its really hard to learn.
