China sees a gold rush and silver crash as investors and a hotel cash in

China is experiencing a major surge in gold investment and production. The country's central bank has been buying gold for 15 straight months, and individual investors, including a billionaire who made $3 billion on gold, are actively trading. A hotel in Macau even ripped up its gold-brick lobby floor to sell the metal as prices rose.

At the same time, there's a sharp downturn in the silver market. A major Chinese silver fund has plummeted in value, and some traders, including the billionaire who profited from gold, are now betting against silver. One trading firm reportedly made $500 million from the silver price drop.
