A big part of the reason why that is the case has to do with the fact that these people assumed that forex trading was something that you could just wake up one day and start doing, but suffice it to say that it is a really complicated process that you need to learn about before you can do it properly.
In order to avoid forexfear, you need to focus at least a few months researching and looking up the various aspects of this trading process. Some might be really eager to get started and they would therefore want to know how much time this learning curve would take to complete in its entirety, but there is no simple answer to this since everyone takes a different amount of time if you think about it.
