Gregmal nails it here, I would add that I think 99% of the time, trying to do what this guy is suggesting ends up losing you money... it's fun conversation while holding a cigar, and a glass of whisky while playing armchair napoleon with your friends by the fireplace, but you will lose money... and if you don't lose money, its actually worse, since you will then have the illusion that you were a genius and you are then likely to lose even more money by trying to repeat what was likely just plain silly luck
