Bitcoin after a Fed rate hike

DISCOVERED   Discovered — found in a sweep, not yet validated

Hypothesis and result

Across 21 hike days from 2015 to 2026 (Fed target rate steps up), Bitcoin was up only 35 % of the time 5 and 20 trading days later against a 56–58 % baseline, median −1.7 % and −1.9 % against +0.7 % and +1.3 %. The half-split holds on both horizons. Equities and gold after a hike sit inside noise. n = 20 from two hiking cycles, p ≈ 0.07 — not family-wise significant.

A hike is not a headwind for equities; it may be one for Bitcoin. Recorded as discovered, graded forward on the next five hikes.
