At time zero, acquiring dollars, gold, or bitcoin achieves a share of that monetary system. As time passes two of these three monetary systems reduce your share - and this reduction is structural, not incidental.
Fiat Currency
US Dollar
~6.5% annual supply growth
M2 money supply has grown about 6.5% a year on average over the past 50 years. Expansion rate is discretionary - there is no upper bound.
Commodity Money
Gold
~1.7% annual supply growth
New mining adds about 1.7% to the above-ground gold supply each year, enough to double it in about 41 years. No one is stealing from you - but the supply expands regardless, quietly shrinking your share of the total forever.
Bitcoin Network
Bitcoin
0% annual supply growth - terminal at 21 million
95% of all Bitcoin has already been mined. The protocol enforces a hard cap of 21 million. No authority can change this. Your share is fixed at the moment of acquisition.

Gold’s figure. The World Gold Council puts the gold above ground at 219,891 tonnes at the end of 2025, and 2025’s mine output at a record 3,672 tonnes (Metals Focus data). Mining therefore added about 1.7% to the stock in the year, a pace that doubles it in about 41 years. The “2%” often quoted rounds this up. Recycled gold is left out, because it is already part of the stock. The rate barely moves even when the price does: record output in a year of record prices still added only 1.7%, because each year’s mining is small beside everything mined before it. Source: World Gold Council, “Are we running out of gold?” (March 2026).

A note on terminal supply. Bitcoin's block subsidy halves roughly every four years and converges to zero around 2140. (The block subsidy is the deterministic, protocol-enforced portion of the block reward - the transaction fee component is variable and expected to grow in economic value over time.) Today, approximately 95% of all bitcoin have already been mined. For this analysis we use the terminal 21 million as the denominator - making the point unambiguous: no matter when you acquire your position, your share of the network's terminal supply is fixed at that moment, and cannot be diluted by any actor, protocol-change, or political decision.

In gold, supply grows benignly - but it grows.
In fiat, it grows by design - and without limit.
In Bitcoin, it doesn't grow. At all. Ever.

This isn't a policy preference. It's a protocol guarantee enforced by cryptographic proof-of-work and economic consensus across a distributed network that no single entity controls. Your 1/21M is 1/21M. Forever.

The Thesis

A fixed share of a growing network may represent an ever-larger fraction of global economic value.

If you accept that Bitcoin's supply is fixed, the next question is: what does that fixed share represent over time? The hypothesis - backed by 15 years of price history - is that monetary energy is migrating from fiat-denominated systems into the Bitcoin network. Any share of the Bitcoin network you hold today - fixed forever, as we established in Part I - could represent a growing fraction of global economic value as that migration continues.

No 4-year holding period has ever produced a negative return.

Bitcoin has experienced multiple 80%+ drawdowns. Yet over any complete 4-year window - through bear markets, exchange collapses, regulatory crackdowns, and mining bans - the 4-year compounded return has been positive without exception. This is not a guarantee of the future. It is an observation about the past.

Historical 4-Year Rolling Compound Annual Growth Rate (CAGR)

Annualized return for every 4-year holding window in Bitcoin's history (approximate, using January prices)
All 4-year windows positive. The trend is declining as Bitcoin matures - consistent with a maturing asset of growing market cap.

These are annualized figures - meaning a 40% CAGR over 4 years doesn't mean 160% total. It means 40% compounded each year, which produces a ~284% total return over the period. The power of annual compounding is precisely what makes these numbers significant.

Your Fixed Share - of the Growing Monetary Network

If your share of the network is fixed, what might it represent - if Bitcoin becomes the dominant, global monetary network, replacing fiat? Explore the thesis with your own assumptions.

This is illustrative only. Past CAGR is not a predictor of future performance. Bitcoin's realized return has declined with each cycle as the asset matures and market cap grows - this is expected and mathematically inevitable. The historical 4-year CAGR average is approximately 65%, declining toward a long-run figure closer to 20–30% over the next decade. The 40% default is a deliberately conservative scenario. This is a thesis - not financial advice.

The certainty is your Bitcoin fixed share.
The thesis is the value of what that share may represent.

Part I of this page is structural - it requires no assumptions. Part II requires you to form a view on the trajectory of the Bitcoin network. The evidence supports the thesis. The conclusion is yours to draw.
