How often is Bitcoin at each level?

How Bitcoin spends its time

Bitcoin spends 56% of all trading days below its trend line. Being under 1.00x is the norm, not the exception.

Volatility decay by cycle

Days per year in each price zone, by halving era. The distribution compresses toward fair value each cycle.

Collapsing volatility

The lines tell the story: Bitcoin's swings around the power law trend are getting smaller every cycle. The distribution's scale has dropped from σ = 0.39 (2010–2014) to σ = 0.15 (2023–2026) — a 2.6× compression. The wild early days of 0.20x and 15x are structurally behind us. Today's range is tighter, the trend more reliable, and being at 0.72x carries more signal than it ever has.

The simple rule

Below 1.00 = Bitcoin is cheaper than its long-term growth line. The lower the number, the bigger the discount. Right now at 0.72x, a return to trend alone means a +39% move — and the trend keeps growing every day.
