The floor is the lowest price Bitcoin has ever traded at relative to its power law trend (0.432x, 15+ years unbroken). Option A (floor-safe) uses only floor prices — the most conservative assumption. For purchases, it sells at floor price and checks the remaining stack's floor growth covers 95% of expenses. For lifestyle upgrades, floor growth must cover the higher expenses outright. Option B tests trend multiples (1.0x, 1.2x, 1.5x) and shows the earliest year the goal becomes achievable if Bitcoin stays near its historical trend. The 5% gap is bridged by loans or other income during storm years.

Model: Giovanni Santostasi's power law (2024). Parameters: logA = -16.493, beta = 5.688, genesis = January 3, 2009. Floor multiplier = 0.432x trend (C3-C4 rolling average P1). Full methodology at btcpowerlaw.nl.
