Testosterone...for traders I know, bragging rights...quick tell everyone how much money they've made...but personally I'd go with experience...there's nothing new in the game, just new ways of attracting the greatest fools. I find once you've done the due diligence and research emotions have minimum influence on your position; though I'm not much of a trader, more of an observer and long term investor.
