Orange Law
Power Law
Bitcoin is not a corporation racing toward saturation and death; it is a city spreading like an epidemic, where users cube with time, value squares with users, and price is simply the network's age raised to the sixth power.

Bands are log-normal quantiles around the fitted law (σ = 0.302 dex). Cycle swings of about ±1σ are typical; a print more than 3σ below the fit would falsify the floor.

The network
Users cube with time. Price grows with those users. Same slope through every boom and crash — the curve doesn’t care.

Your stack
Enter how many bitcoin you own and a date. Each quantile is the model price that day, the matching stack value, and the annualized return versus today.

Self-custody
The power law only helps if you still hold the coins. A hardware wallet keeps the keys offline — Trezor built the first one, and it still only signs what you confirm on the screen.

200-week moving average
Bitcoin’s 200-week moving average (200WMA) is the average of weekly closing prices over nearly four years and functions as a slowly rising long-term cost basis and historical cycle floor. When the market price trades near or below that line, Bitcoin has historically been considered cheap and in an accumulation zone at cycle bottoms; when price trades at large multiples above the 200WMA, it has typically been regarded as expensive and late-cycle. Today is 1.19× — closes below the 200WMA occur 8.3% of days.

Scale-free nature
Same log-log plane as Bitcoin. Each line is y = A xβ with the exponent from the source paper — slope is the law. Zipf, city rank-size, and Bitcoin’s on-chain wealth tail sit near β = −1. Kleiber rises; Pareto and Gutenberg–Richter decay at other slopes.

The $1 trillion club
Clock starts at founding — Genesis for Bitcoin. Bitcoin is daily price times circulating supply. The others are quarterly market cap from the IPO through the first $1 trillion print. Bitcoin is the orange used above.
Equities
The power law is a diminishing-return curve: the same exponent on a larger age each year, so the implied one-year gain shrinks. Today that path still prices a 36.7% year. On a phone the orange line is only that smoothed curve, so it stays readable. The S&P line is still the actual trailing return through today, then 10% dashed.On the chart, both lines are actual trailing one-year returns through today. After today bitcoin follows the power law and the S&P follows 10%, both dashed. Drag either chart. Tap a name to isolate the line.

Solid lines are trailing one-year returns through today. The faint orange line is the smoothed power-law one-year return, also through today. Dashed bitcoin continues that power law. Dashed S&P is a 10% assumption.

The law
Santostasi and Perrenod show the exponent is not a free fit. Address growth scales as t3.05 (epidemic spread on a scale-free network) and price scales as N1.84 (generalised Metcalfe). Their product is the observed β.
Fit on daily closes from 17 July 2010 (day 560 after Genesis) through February 2026. Floor is the −2σ quantile; a year below −3σ is the published falsification test. Fiat units other than USD (CAD, EUR, TRY, and the rest) convert each day’s dollar close by that day’s FX — the path moves with the currency, it is not a frozen multiplier. GOLD is not a dollar conversion: it is Giovanni’s Gold/BTC power law (β = 5.41, σ = 0.330 dex) in ounces per bitcoin, using each day’s gold price. Native CAD, gold, and live FX still feed the day-over-day change. Compare overlays use Yahoo Finance adjusted closes (S&P 500 total return, XIC.TO for the TSX, CNQ.TO, NVDA, AAPL, COST) converted into the selected unit the same way bitcoin is, then indexed to bitcoin's price at the left edge of the view so each line is the growth of the same starting dollar.
