But it can't be emotional move because of situation became scary for you at the moment. Only if such move was planned from the start.
Not everyone has planned from the start. The new people who start trading without the knowledge of market spread wont be able to decide on what price to set buy or sell orders. They will end up buying high and selling low - leading to a huge loss and then they will go to their friends and say "Trading is usless and exchanges are scam." 
We all fail to notice our own mistakes. Its true that mistakes happen but then you must rectify it and learn from them not to repeat them.
