Why Bitcoin has value

Backed by nothing misunderstands where value comes from

The most common objection to Bitcoin is that it is backed by nothing. It is a fair thing to ask. So ask it of the money already in your pocket.

The US dollar has not been redeemable for gold since 1971, when the last link was cut. No major currency today is backed by a physical commodity. The dollar holds value because it is scarce enough, useful enough, and widely accepted, and because people trust that it will still be worth something tomorrow. That is what backs it. Not a vault of metal, a shared agreement.

Even gold makes the point. Only a fraction of its price comes from industrial use in electronics and jewelry. The rest is monetary premium^{The extra value an asset carries because people use it to store wealth, beyond what its practical use alone would justify.}, the value people assign to it purely because it works as a place to store wealth. Gold is not prized because you can wire a house with it. It holds its worth because it is scarce and hard to fake, and people have agreed on that for thousands of years. Once you see that money gets its value from properties and trust rather than from a thing behind it, the question changes. It stops being does Bitcoin have anything behind it, and becomes does Bitcoin have the qualities that make good money. That second question also sits at the heart of the claim that bitcoin has no intrinsic value.

Scarcity no one can dilute

Start with the property that fiat currency cannot offer at all. Bitcoin has a fixed limit of 21 million, written into the rules from the start. New bitcoin enters circulation on a set schedule, and that schedule only slows. About every four years a halving^{A scheduled event about every four years that cuts the new bitcoin paid to miners in half, steadily slowing issuance toward the 21 million cap.} cuts the rate of new supply in half. Nearly 95 percent of all the bitcoin that will ever exist has already been issued, and the last coin is not due until around the year 2140.

Compare that to a dollar, a euro, or a peso. When a government needs more, a central bank can create it. That is not a flaw in how those currencies are run, it is how they are designed to work. But it means the supply can always grow, and when it grows faster than the economy, each unit you hold buys a little less. That slow leak has a name, debasement^{Reducing a currency’s value by expanding its supply, which quietly erodes the purchasing power of everyone holding it.}. Bitcoin was built so the leak cannot happen. Its price still swings from week to week, sometimes hard, so it is a rough ride over short spans. The claim is narrower and sturdier than being a smooth inflation hedge. No one can inflate the supply out from under you.

The real circulating supply is smaller than 21 million. Some of it is already gone for good, stranded on discarded drives and in wallets whose keys are lost. No one can say exactly how much, though the estimates run into the millions. Either way the effect points one direction. Bitcoin is even scarcer than its own code suggests.

Better than gold at gold’s own job

Scarcity alone does not make good money. There are rare baseball cards and one-off paintings, and nobody prices their groceries in them. A store of value also has to be durable, portable, divisible, and easy to verify. This is where the comparison to gold gets interesting, because Bitcoin takes the qualities that made gold money for millennia and improves on several of them. Gold still wins on a couple of counts, since it needs no electricity and no network to survive. On moving, splitting, and verifying value, though, Bitcoin pulls well ahead.

Gold is durable and scarce, which is why it held the job so long. But it is heavy, hard to move, and hard to check. Try sending an ounce across the world in ten minutes, or splitting it to buy a coffee, or proving on the spot that a bar is not gold-plated tungsten without specialized equipment. Bitcoin travels anywhere there is an internet connection in minutes, divides into 100 million satoshis^{The smallest unit of Bitcoin, one hundred-millionth of a bitcoin (0.00000001 BTC). Named after Bitcoin’s pseudonymous creator.} per coin so you can hold any fraction you like, and can be verified by anyone in seconds without trusting a middleman. It carries gold’s strengths and drops gold’s friction, which is the real case behind the argument that gold is superior to bitcoin. You do not need to buy a whole one to start, a point worth its own look at why you do not need a whole bitcoin.

No issuer, no CEO, no off switch

A fixed supply is worth nothing if someone can quietly raise it. Plenty of projects have promised scarcity and then changed their minds. The reason Bitcoin’s cap can be trusted is that there is no one with the authority to lift it.

Bitcoin has no company, no CEO, and no boardroom. It is open-source software run by a global network, where the rules are enforced by tens of thousands of independent computers called nodes^{Computers running Bitcoin software that each store the full ledger and enforce the rules. Tens of thousands run worldwide, with no central one to shut down.}. Each one checks every transaction and every new coin against the same rules, and rejects anything that breaks them. To raise the 21 million cap, you would have to persuade that entire network to adopt the change, and the people running it are the same people who hold bitcoin and would lose out if it were diluted. The incentive runs the wrong way for an attacker and the right way for everyone else. This is the deeper story of bitcoin decentralization and security, and it is also what lets you hold the asset outright rather than through anyone else, the idea behind how Bitcoin secures your wealth. Value here rests on math and consensus, not on marketing or a policy that can turn on a Tuesday.

Value that compounds as more people use it

Here is the part worth pushing on. Properties do not create value by themselves. A perfectly scarce, perfectly portable asset that nobody wanted would be worth nothing. Value in any money ultimately depends on other people accepting it. That is true of gold, true of the dollar, and true of Bitcoin.

What those qualities do is make Bitcoin worth adopting, and then hold the value in place as adoption grows. Like any network, it becomes more useful as more people join. Each new holder adds liquidity and reach, each merchant adds a place to spend, and each year it keeps working adds to the case that it will keep working, a slow monetization^{The slow process of something becoming money, as more people hold it for its own sake and it takes on a monetary premium.} that has run for over fifteen years. The fixed supply is what makes that flywheel durable. When demand for a normal currency rises, the issuer can print more and capture the gain. When demand for Bitcoin rises, the supply cannot budge, so the value shows up in the coins people already hold. And through the Lightning Network^{A payment layer built on top of Bitcoin that settles small transactions almost instantly and at very low cost.}, the same asset that works as long-term savings also handles fast, low-cost everyday payments.

Common questions

The question of why Bitcoin has value turns out to be the question of what money is. For most of history the answer was chosen for you by whoever controlled the supply, and the choice was rarely in your favor. Bitcoin puts a different option on the table. It offers a money that is scarce by rule rather than by promise, that anyone can hold and verify, and that no authority can quietly water down. Whether a money like that is worth holding is a judgment you get to make for yourself. Not long ago, that option did not exist.
