It's because a whole lot of the people here aren't actually trading based on analysis and experience, but are just blindly speculating on the market to increase or decrease. This is called gambling -- some times you end up having done the right thing, and some times you have to swallow a loss. It's the wrong attitude of course, but it shouldn't really surprise anyone that most people here don't know what they are doing when trading. Eventually when they have lost their entire capital due to their stupidity, they will realize what they have done wrong, but then it's too late already.
