Even if you do not know much about gold you are surely aware that it is a rare and precious metal. Before the implementation of the paper notes and coins that we accept today as money, gold was used as the medium of exchange. Even in the present time, gold is used as a store of wealth and value. Investing in gold historically has very good returns on investment in the long term. Because it is a precious and rare metal and its supply is limited, demand for it always keeps on increasing. There has never been enough production to meet the world demand of gold.
