Digital Currencies, Another Step in the Evolution of Money
Throughout history people have used different mediums of exchange: cattle, salt, and even seashells. Metal coins became a useful currency as they are perceived to hold inherent value. When people got fed up with carrying around piles of metal, paper money started being used.

The Evolution of Currency
Barter initially existed before money came into play; this was an exchange in which people traded items for other items. Commodities such as salt, seeds, weapons, food, cattle, tools, clothes and anything else of value were traded amongst people. Livestock such as camels, sheep, and cows were commonly accepted currency by around 10,000 years ago. Grain was also commonly used as currency.
