http://onlygold.com/Info/All-The-Gold-In-The-World.aspJust something to keep in mind for all the people including myself who think or thought we might now or might have in the past been in a bubble. Given cryptos have become more popular than gold from a media reporting perspective, not necessarily from an average joe investing perspective (though really few people own substantial amounts of gold either), and people love to invest in new technology and new ideas, I wouldn't be so quick to dismiss the idea that this space could end up becoming a 1.5-3.0 Trillion dollar space, or even more.
