What makes me go hmm? The hysterical nature of the internet.
Even though it's been mined for many centuries gold is still very rare which is why it's so expensive. Melt it down and you can fit all the gold on earth into 2 olympic sized swimming pools, not a huge amount when you think about it.
Man has been mining gold from the earth for thousands of years.
In the last 200 years the speed and efficiency has increased dramatically. Gold is being pulled and refined from areas of the world that were previously inaccessible.
Where is it?
Where is all this gold that it's not visible in daily life? At least not as visible as it should be by now. What countries are still on the gold standard and actually have piles of gold still? The U.S. and U.K. don't have any.
