method · ratio = BTC-USD close ÷ COMEX gold front-month close (yahoo GC=F), on days both print. fair value = month-end ratios; main read = median and 25th–75th percentile of the last 60 completed months, context = the same over all months since Sep 2014 (first BTC-USD month on yahoo); percentile = share of those months with a lower ratio. chart band = rolling: each month uses the prior 60 completed months. verdict rule: percentile 40–60 = fair; otherwise ratio below the 60m median = btc is the value side, above = gold is the value side. momentum = each leg's % change from the last common close on or before the base date (YTD base = last close of the prior year).
