Crisis and Opportunity a system that goes back to early 1800s, when British investor Barron Von Rothschild said, “the time to buy is when blood runs in the streets, even if that blood is your own.” And he should know; the good Barron made a fortune buying during the panic that preceded Waterloo. This is a money-making method that is famously used by Warren Buffett: Back in late 2008, as presidential candidate John McCain panicked and rushed to Washington from the campaign trail to save the banks, Mr. Buffet was stepping in to buy GE at a steep discount. The Crisis & Opportunity system can be summed up with four words so simple, a five-year-old can understand: “Buy Fear. Sell Greed.”
