This week, the world's top 500 richest people lost a total of $500 to $1 trillion - the largest wealth evaporation in Bloomberg's history. From Silicon Valley to Wall Street, from cryptocurrencies to commodities, there is no exception. Someone evaporated billions of dollars overnight. The only one who made money against the trend is the investor who has always been slow, steady, and ridiculed by many as "old-fashioned" - Warren Buffett. When the foam burst, cash was king, and value investment was no longer outdated. The tide has receded, and this time there are even more swimsuits to wear than before.
