For many centuries, gold has been known as valuable item. There were so many important key events in the world caused or related to gold; one of the most popular was the attack from the Portuguese to Maya and Inca tribes. Because of the value, more people invested their money on it. Some of the kept bullions and some others were still conventional by choosing jewelries.
When gold investment compared with other metallic investments, there is a fact said that gold is safer and more profitable. We can take example from platinum. Even this gem has higher price but it is very risky because the fluctuation of the price cannot be predicted, besides, it is little bit hard to convert it to be cash. The same things happened on silver. It is not promising because the price is quite cheap and the price increases rarely.
It is easy to find gold because it is traded in many markets above this planet. The larger gold markets are in New York and London. They operate 24 hours a day. Gold markets are very important because it functions like a stock exchange. It is not only place for buying and selling but also the monitor to update price.
