yes i agree that greed is the main factor , but i will alsoo blame the unawairness off the trader , when a trader dont follaw the basic fundamentals of trading and go for big risks on the very early stages, to get big money , but he forgets to learn 1st than earn , i m trying to learn main technical ones to understand fluctuations of the market, soo in future i will be able to take the decision that rewards me money , will also away from loss.best of luck
