I must be dumb. I do not get what Paul meant when he said “if you lose you could lose real big”. He said not to use one strange rule to buy stock, since, if you lose you could lose real big. He is not sure Blaise was right. He thinks joy and pain can be just so big. Why does he care that if you lose you could lose real big. If you buy by that strange rule the chance you lose is so so small. If the chance is so so small and if Blaise was wrong, who cares ? Why are the one strange rule guys dumb ? Help me smart guys. I do not get it.
