Metals

Metals have always been used as means of exchange between traders and as a store of wealth, with gold being the metal most commonly used for this purpose. Today there are many ways to invest and trade in gold and other metals.
Why people usually buy metals:
Systemic financial concerns. When banks and money are perceived as unstable and/or political stability is questionable, gold has often been sought out as a safe store of value. 
Inflation. 
War or political crises. Conflict and political upheaval have always sent people into a gold-hoarding mode.
