It’s no surprise that the world needs some sort of a currency system to handle trade. Since it can be anything, such as stones and metals, why do we always hold gold so valuable compared to other metals? If you really think about it, for almost all major civilizations, gold had been quite steadily used and valued. There are many reasons behind this phenomenon, but some of the main ones are as follows:

a) Gold is universal. It can be used anywhere in the world, therefore making it flexible and trustworthy.
b) Trading gold has single pricing due to it being only one grade. You won’t have to deal with grades and quality.
c) Gold is very easy and affordable to test.
d) Gold does not corrode.
e) Last, but not the least, gold is extremely dense, which makes it easy to handle.
