Gold is an element on the periodic table. It is formed through supernova explosions throughout the universe. So, if you are referring to the amount of gold in the universe, it is quite a bit larger than what we have on Earth,
On Earth, we’ve mined about 171,000 metric tons and have discovered another 57,000 metric tons. These tons are believed to have been delivered to the planet about 200 million years ago during an asteroid bombardment (during the Earths formation, more gold and precious metals were subsumed into the prime dial Earths core. So we’re not getting our hands in that stuff). Absent another bombardment, it’s not likely we will find much more recoverable gold than we’ve identified. It’s rare to find gold; hence, it’s value. As other have pointed out, it has uses other than a store of value such as jewelry or other decoration, along with a growing amount of industrial uses in technology. That said, all of the gold mined in history still exists. Might be in Mike Tysons’s tooth, or buried deep in an Egyptian tomb, but it’s there. It’s nearly indestructible but, at the same time, malleable and with an attractive color. We can chemically verify it, so there’s no dispute whether it’s gold or not. And you can’t make something that isn’t gold into gold.
Another attribute of gold is that, for 99% of human civilization, it was money. Not kind of like money, but actual money. Sure, you could issue pieces of paper and use those pieces of paper to facilitate trade. But those pieces of paper, whether issued by a government of a bank, were not money. They were notes. Redeemable, upon presentation to the issuing entity, into an agreed upon amount of gold. Not just in Roman civilization, or the Middle Ages. As recently as 1971, gold was the anchor of the international monetary system. In fact, that’s why our dollars say Federal Reserve Notes. Nixon decided that these notes weren’t redeemable anymore in 1971. But before Nixon, it’s also the item which prevented countries from running persistent current account deficits into perpetuity. If we bought more from one country than they from us, gold would flow to our trading partner. They had more money. And it would reside in their banking system, allowing more loans to be issued within that country. The country that lost gold would see its monetary base shrink, and its amount of available credit shrink. It’s economy would likely contract, and pressure would fall upon merchants or producers to sell what they could often resulting in price declines, Today, we call that deflation. And in the country with more gold (read, money)? It would grow, and grow quickly leading to spikes in demand and, ultimately, higher prices. Those higher prices (inflation) would meet their match when the other trading partner’s now relatively lower prices would seem attractive., Guess what would happen? Purchases of their goods would increase, and gold would flow back. And the cycle would continue. It was a self correcting monetary system, not without volatility. Of course, the volatility would not come from the price of gold. It, after all, was money.
Funny thing, too. If you track the increase in the price of gold over time, and compare that to the purchasing power of the dollar, you’ll see an interesting correlation. In other words, even though gold no longer backs the dollar, the price of gold bears a strong relationship over time to the purchasing power of the dollar. Think of the inverse of the dollar price of gold as the gold price of a dollar. Amazing, but the market still views the relationship holding.
So, with that context, how to compare to bitcoin? It has no history. It wasn’t created in the explosion of a far off star and miraculously found its way to Earth, Some dude or dudes conjured it. It is not money. It’s price moves have nothing to do with changes in the purchasing power of any currency. No merchant or country of scale accepts bitcoin as payment or prices it’s products or services in bitcoin. It exists in a computer, conjured by someone or something that no one knows. It’s program says there is a limited number of coins. Maybe that’s true. Maybe it’s not. Others harness massive computing power which uses a TON of electricity to crack codes to release more bitcoin. That’s not a joke, more global warming to find things that don’t exist in the real world. That is truly sad.
When asked to explain, then, how one should consider bitcoin as a store of value akin to gold, the responses center around “things change,” or people who scoff at crypto enthusiasm are “closed minded.” I’d offer a suggestion. If you want to convince people that bitcoin is legit, show how it can become a medium of exchange or a non volatile store of value akin to gold. No one has, and that’s why, speaking for myself, crypto is viewed as a speculative gamble. Supporting it is a religious belief. Now, many have made money with that religion, so there is that. But what price to sell? What price to buy? What’s it worth? How do you determine what it’s worth? Questions demanded by investors seeking assets at a discount to value, but not questions asked by religious devotees.
