Cumulative BTC held — the staircase. Each step is a disclosed purchase; the step height is the size of the buy.
Purchase bubbles — one per buy. Bubble size is the BTC count; vertical position is the per-BTC cost basis. Small-and-high is a small buy at a high price; big-and-low is a big buy made cheap.
Share price — the secondary line on the right axis. Did the company stack faster when its equity ran hot?
Regression fit — the best of a Richards and a Gompertz saturation curve, chosen by log-R². It has to flatten: there are only 21 million Bitcoin.
Controls — Linear/Log switches the BTC axis. Play animates the curve forward through disclosure time. ‹ › steps through the cohort by holdings.
