Let's see how gold and Bitcoin stack up against each other.
Satoshi Nakamoto envisioned Bitcoin as a kind of digital gold, and Bitcoin has often been positioned as a kind of competitor to gold.
But despite that, they're more similar than they're different. To highlight this we compare their respective scarcity, as measured by stock to flow ratio, the culture of value that's emerged around both and the practical applications of both gold and Bitcoin.
In this guide:
At a glance: Buying gold vs Bitcoin
Gold
Why buy?
- Proven value
- Wide range of ETFs and funds
- Little correlation with other asset classes
Bear in mind:
- Physical asset requires physical access
- Storage and transport expenses
- Potentially smaller profit opportunity
Bitcoin
Why buy?
- Potentially larger profit opportunity
- Purely digital, globally accessible, easily transferred and stored
- Little correlation with other asset classes
Bear in mind:
- Volatile market
- Few ETFs and funds
- Unproven value
You can skip ahead to learn more about reasons to buy Bitcoin and gold as well as what to consider.
Scarcity of gold vs Bitcoin
To compare their scarcity, we'll use stock to flow ratio.
This measurement refers to the ratio of the new annual supply (flow) to the total existing supply (stock). To find the stock to flow ratio, simply divide the stock by the flow.
| Gold | Bitcoin | |
|---|---|---|
| Existing supply | 190,040 tonnes | 17,560,000 BTC |
| Inflation rate | 4,000 tonnes | 657,000 BTC |
| Stock to flow ratio | 54 | 27 |
You could think of stock to flow ratio as an all-in-one "scarcity score".
Gold has a scarcity score of 54 (very scarce) and Bitcoin currently has a scarcity score of 27, which is also pretty darn scarce.
For perspective, no other well-known asset comes close to the stock to flow ratio of gold or Bitcoin. Silver's stock to flow ratio is estimated to be about 20, while most usable commodities such as non-precious metals tend to have a stock to flow ratio closer to 1, meaning the world produces and consumes roughly the same amount each year.
When a commodity has a stock to flow ratio near 1, it's highly vulnerable to market conditions. With a stock to flow ratio closer to 50, it's much more resistant.
How scarcity insulates value
Stock to flow indicates how robust the price of something is in the face of outside influences.
For example, demand for gold often increases in India around the festival of Diwali, because it's traditionally celebrated with gold and jewellery, so there's typically a corresponding bump in local gold prices.
But gold prices globally would barely notice if Diwali was cancelled one year. An asset with a lower stock to flow ratio would crash in the same situation because the market would end up grossly oversaturated in anticipation of the Diwali that never was, but gold would barely notice. Even if you were to double the total supply of gold produced in one year, you'd only make a small difference to the total amount in circulation.
Bitcoin's stock to flow ratio may be imbuing it with a similar robustness.
At its current rate, it would take 27 years of Bitcoin mining to double the current supply.
But it won't stay at its current rate. Bitcoin's stock to flow ratio is designed to increase over time, with periodic cuts to the supply, commonly referred to as "halvings" or "halvenings" if you want to be cute about it.
Despite all its volatility and mania, Bitcoin prices have been consistently finding a price floor in a way that correlates with the asset's stock to flow ratio.
| Year | Bitcoin yearly low | BTC stock to flow ratio most of that year |
|---|---|---|
| 2009–2011 | $0 | 0 |
| 2012 | $4 | 9 – the first halvening |
| 2013 | $65 | 10 |
| 2014 | $200 | 11 |
| 2015 | $185 | 12 |
| 2016 | $365 | 25 – the second halvening |
| 2017 | $780 | 26 |
| 2018 | $3,200 | 27 |
The next halvening is on track for late May 2020. And as you can see, the market has historically priced it in beforehand, so assuming that trend holds, 2019 is going to be a big year for Bitcoin. It certainly has been so far.
Practical applications of gold vs Bitcoin
But scarcity alone isn't enough to give something value. Gold, Bitcoin and everything else need something to make them valuable in the first place.
Let's start with the more interesting stuff: a culture of value.
Practical applications in gold
Gold gets dug out of the ground in Africa, or someplace. Then we melt it down, dig another hole, bury it again and pay people to stand around guarding it. It has no utility." – Warren Buffet
We can see this in gold, where a small nugget of practical applications in electronics and other industrial applications exists, but most of the gold mined each year goes to jewellery, bars, coins, ETFs, central bank purchases and other purely store of value applications.

The thing about many of those more utilitarian applications is that gold is the single best material for them. It's a highly efficient non-tarnishing conductor and a consistently reliable non-reactive metal. The high price is actually a downside here, but gold is still the best tool for the job.
There is no practical substitute for gold there and a cultural undercurrent of value wrapped around a core of practical applications makes the metal an effective store of value.
Practical applications in Bitcoin
[Bitcoin is] just dementia. It's like somebody else is trading turds and you decide you can't be left out." – Charlie Munger
Bitcoin also has a core of practical applications. The primary function of the Bitcoin digital currency (BTC) is to serve as the incentive mechanism which powers the Bitcoin blockchain. Bitcoin miners are rewarded with BTC, so the more valuable BTC is, the more energy they can afford to put towards mining it.
And the more energy that goes towards mining it, the more resilient the Bitcoin blockchain becomes. Resilient, in this case, means immutable and tamper-proof. Having a properly immutable and tamper-proof digital ledger opens up a range of practical applications.
The first and most obvious is censorship-resistant payments of BTC itself. The second is the use of BTC as a resilient digital store of value.
The same way the gold content of jewellery lets people easily carry a reliable amount of monetary value on their person, Bitcoin lets people carry around a store of monetary value in their heads (if they have an incredibly good memory), write it on a piece of paper, get it tattooed on their favourite body part and so on.
And the Bitcoin blockchain itself, which only works if BTC is sufficiently valuable, can also be bent to a wide range of practical applications. Chief among them is the ability to run "side-chains" alongside Bitcoin, borrowing its security for a wide range of practical applications.
The Bitcoin metronome
One example is a system called Factom, which turns the Bitcoin blockchain into an immutable, robotic data management and notary service.
When people use Factom, they're essentially using a machine that takes in data and then uses the immutable heartbeat of the Bitcoin blockchain to automatically timestamp the managed data as it goes. Because it leans on Bitcoin, it provides an almost perfect, near 100% guaranteed tamper-proof way of managing data.
To do this, the Factom network consumes small amounts of Bitcoin with each timestamp.
It's already making its way into the real world. Factom is working with the Department of Homeland Security to use the Bitcoin blockchain to create lifetime records of individual devices, immutably secured against the Bitcoin blockchain. At a time when international cybersecurity is a growing concern, the ability to trustlessly guarantee the immutability of data is uniquely valuable.
This is just one of many examples of systems that rely on the Bitcoin blockchain.
As with gold, there is no practical alternative to Bitcoin for many of the applications that currently use it.
It's true that anyone can "fork" the Bitcoin code and create a technically identical replica, but these replicas don't capture the monetary "culture of value" of BTC, which is exactly what makes the Bitcoin blockchain so useful.
The intrinsic value of gold vs Bitcoin
If something is desired, it will become valuable. With a sufficient stock to flow ratio and enough people who want something, this "culture of desire" spreads more easily than it shrinks, and is well insulated against market shocks.
This has been seen in gold in previous centuries. Where two societies, one which values gold and one which does not, encounter each other, the former spreads its gold appreciation to the latter, rather than the latter spreading its gold indifference to the former. This is because:
- Carrying a lot of monetary value is a practical application in itself, so when more people believe in the value of gold it genuinely becomes more useful and valuable.
- A high stock to flow insulates the value of gold against supply shocks which would otherwise undermine this trend.
This culture of desire is now alive and well in gold. You probably don't remember anyone ever sitting you down and teaching you that gold is valuable. It's just one of those things that's ingrained in almost every culture and passed on as a simple truth. You never had to learn gold is valuable for the same reason you never had to learn the sky is blue.
Today we live in an increasingly digital world. A lot of people are now manually learning that purely digital assets can be valuable, but for the younger and more Internet-oriented, this is just one of those pieces of ingrained knowledge.
Gold mining is a waste, but that waste is far less than the utility of having gold available as a medium of exchange. I think the case will be the same for Bitcoin. The utility of the exchanges made possible by Bitcoin will far exceed the cost of electricity used. Therefore, not having Bitcoin would be the net waste." – Satoshi Nakamoto
There were 2.6 million Internet users in 1990. 10 years later, in the year 2000, this had grown to 500 million. By the time the first Bitcoin block emerged in 2009, the world had almost 2 billion Internet users. Since then it's more than doubled to over 4.5 billion and today more than half the world's population is Internet-connected.
We live in a digital world, so it's only natural that we would invent some kind of digital gold for it.
