Gold trading investment requires a simple approach. In the 14th century, Oakham proposed the principle of simplicity, or Oakham's razor principle.

He stipulated that if there is a set of theories that all explain the same thing, the preferred one is always the simplest, the one that requires the fewest assumptions. At Princeton, when the two "lone rangers" Einstein and G?del met by chance on a dense forest trail, they may both be thinking about one theme involuntarily: simplicity. The former said when explaining physical theory that simplicity is beauty. When summarizing mathematical principles, the latter lamented that there are actually very few theorems that humans can truly prove. In Cambridge, Keynes usually made investment decisions by sitting on the bedside before getting up in the morning, spending a little time reading various newspapers and periodicals. In Omaha, Nebraska, the life of Buffett and Menger, the best partners far away from the hustle and bustle, is even simpler. Living comfortably in the small town, they are still the most successful investors in the last century.

Investing requires a simple strategy. Former U.S. Treasury Secretary Rubin once proposed four principles for decision-making: first, the only thing that can be certain is the uncertainty of other things; second, every decision is based on the weighing of probabilities; third, use decisive action to deal with Uncertainty; fourth, excellent decision-making procedures are more important than excellent decision-making results. These are a good remedy for people who spend all day in K-lines and numbers.

The same is true in the gold investment market. It is impossible to be too conservative or too risky. You must first survive safely and then consider making money. In the words of rugby, soccer, go and chess, the surest offense is the best defense. In the language of risk control, making funds appreciate quickly and controlling investment risks are basically the same thing. "Excessive risk appetite" often becomes the biggest weakness of losers. Business talents who are eager for quick success are often not as good as evergreen businessmen who believe in doing business with common sense.
