Why Your Money Needs a Better Unit of Account Definition—And Why Bitcoin Might Be It

The Hidden Problem With How We Measure Value

Ever wonder why your paycheck buys less every year? The culprit isn’t just lifestyle creep—it’s a fundamental flaw in how we measure economic value. In macroeconomics, this measurement system is called a unit of account, and it’s broken.

A unit of account is the standard by which we compare the value of goods, services, and assets. It’s the common denominator that lets you understand why a house costs 100x more than a car, or why inflation erodes your savings. Countries use their own units: the euro (EUR), British pound (GBP), or yuan. Globally, the U.S. dollar (USD) dominates international pricing and cross-border transactions.

But here’s the problem: traditional fiat currencies suffer from systematic devaluation through inflation. This makes long-term value comparisons nearly impossible.

What Makes a Unit of Account Actually Work?

For something to function as a unit of account definition that markets accept, it needs three critical properties:

Divisibility is first. A unit of account must break into smaller pieces without losing value. This lets you transact at any scale—whether buying a coffee or a factory.

Fungibility comes second. Each unit must be identical and interchangeable. One dollar equals another dollar; one bitcoin equals another bitcoin. This uniformity makes value calculations consistent and trustworthy.

Stability is the third pillar—and this is where conventional money fails. Inflation destroys this stability by design.

Why Inflation Breaks Your Ability to Plan

Inflation doesn’t just make goods expensive; it makes the unit of account itself unreliable. When prices shift unpredictably, comparing asset values becomes guesswork. Should you invest in property or bonds? Save or spend? Without a stable measurement, macroeconomics becomes dominated by uncertainty, not analysis.

Central banks actively inflate currency supplies to fund spending and stimulate economies. The U.S. dollar, euro, and yuan can all be printed infinitely. This means the yardstick measuring your wealth literally shrinks over time—your savings are worth less, not because you spent more, but because the unit itself was devalued.

Market participants can’t make informed decisions about consumption, investment, and savings when the measurement system itself is unstable.

Bitcoin: A Unit of Account Built for Stability

What if you had a unit of account that couldn’t be inflated away?

Bitcoin has a fixed maximum supply of 21 million coins. No central bank can print more. No government can dilute it. This creates an unprecedented property in monetary history: a scarce, censorship-resistant standard of value that operates globally without institutional gatekeepers.

For businesses and individuals, this changes everything. With Bitcoin’s inelastic supply, you could plan long-term finances with genuine confidence. A contract priced in Bitcoin today holds the same real purchasing power tomorrow, without surprise inflation eating into profits or savings.

If Bitcoin became a global reserve currency, it would eliminate currency exchange costs and reduce the risk of exchange rate fluctuations. International trade becomes cheaper and more efficient. Cross-border transactions lose their friction.

Beyond that, a stable unit of account removes the political temptation to print money for stimulus. Governments would need to drive economic growth through innovation, productivity, and investment—not monetary manipulation.

The Catch: Bitcoin Still Isn’t There Yet

Bitcoin possesses the theoretical properties of an ideal unit of account: divisibility, fungibility, and inflation resistance. It’s also globally accessible and censorship-resistant—genuinely novel in macroeconomics.

But adoption isn’t automatic. Bitcoin is still young and volatile. For it to function reliably as a unit of account definition across business and consumer transactions, it needs broader acceptance, reduced price swings, and regulatory clarity. The technology works. The economics align. What’s missing is time and scale.

The unit of account that emerges as winner will be the one that best protects value over time. Traditional fiat currencies are structurally designed to lose value. Bitcoin is structurally designed to preserve it. That asymmetry matters more than most realize.
