AI Summary
5 min readIn the fall of 2025, as Bitcoin hovered around $62,000, many market participants declared the four-year cycle dead and called for a breakout to new highs. Matthew Mezinskis, who has tracked Bitcoin’s power law since 2018, was not among them. He watched the price fail to reach the upper quantile bands of his model, warned his stream that the cycle was intact, and then watched Bitcoin drop 53% from its peak. The cycle was not dead. The power law was not broken. And the statistical evidence, he argues, was there all along.
What the power law actually is
Mezinskis distinguishes the power law from the constant-growth models that dominate traditional finance. Constant growth—10% per year in the stock market, or a fixed interest rate on a loan—is exponential. It compounds at a steady percentage. Bitcoin does not behave that way. Its growth rate has been decelerating over time: roughly 1,000% per year in the early years, down to about 40% per year on trend today. That is a power law: the rate of growth is proportional to the system’s size and time in existence, not a fixed annual return.

What you'll learn
- 1 (00:02) **Power Law vs. Exponential Growth** - Matthew defines the core distinction: Bitcoin's growth is a power law (proportional, decelerating) not constant exponential growth.
- 2 (01:42) **Power Law Refresher & The "Broken" Question** - Matthew explains the power law as a proportional, scale-invariant relationship, not a channel or support/resistance line.
- 3 (05:56) **What Would Break the Power Law?** - Matthew defines the specific conditions that would invalidate the power law model.
- 4 (07:20) **Why Stock-to-Flow Failed (and Power Law Didn't)** - Matthew contrasts the power law with the failed stock-to-flow model.
- 5 (13:07) **What Would Break the Power Law? (Detailed)** - Matthew elaborates on the specific conditions for the model to break.
- 6 (17:00) **Why Bitcoin Can't (Currently) Follow Exponential Growth** - Matthew explains why Bitcoin's growth is power law, not exponential, and why that could change.
- 7 (20:07) **Visual Evidence: Exponential vs. Power Curve** - Matthew shows charts demonstrating that the power curve fits Bitcoin's price history far better than an exponential trend.

“I think in ten years, the financial system and the Bitcoin system are going to collide.”
Matthew Mezinskis is a macroeconomic researcher, host of Crypto Voices and one of the leading voices on Bitcoin's power law and global money supply data.
In this episode, we get into whether the Bitcoin power law has finally broken, why the four-year cycle still appears intact, and what the data suggests about the current market and a possible $500,000 Bitcoin in 2029.
We also explore the coming collision between Bitcoin’s slowing power law growth, a financial system built on exponential credit and whether Bitcoin will force that system to change or ultimately be co-opted by it.
