Attention — Bitcoin vs AI
Analysis — does it lead price?
Waiting for the analysis response…
Levels lie. Price and every attention series here are near unit-root; correlating levels manufactures a relationship (Granger–Newbold). Price enters as log returns, sentiment as a difference, log-difference, rolling z-score or deviation from a trailing median, and ADF and KPSS are reported so you can see whether the transform worked.
Alignment. Daily series are joined on the UTC date; the Fear & Greed value stamped at midnight UTC describes the previous day, so contemporaneous tests shift it back one day. Weekly Google Trends points are labelled by the Sunday that starts the week and paired with the Saturday close, six days later; CFTC positions are as of Tuesday and paired with Tuesday's close. The exact rule used is printed above.
Fear & Greed is half price. By alternative.me's own description, volatility (25%) and momentum/volume (25%) are computed from price and volume, dominance from market caps, and the survey component is paused. A test of the index against returns is partly a test of returns against themselves.
Google Trends is renormalised on every pull. Each request is scaled so its own maximum is 100; values are comparable within one pull only. Every refresh re-pulls the whole window and the page always reads the newest complete pull. A ratio of two such indices is a ratio of two arbitrary scales.
Apathy ↔ Hype Index. Each component is first put on a daily calendar: the monthly worldwide Trends values enter on the last day of their month (when the month is complete) and carry forward, with Google's integer 0 read as 0.5; Wikipedia views are a 28-day sum; active addresses, spot volume, the Coinbase rank (negated, so #1 is high) and Fear & Greed are 28-day means. The components that grow with adoption (both searches, Wikipedia views, active addresses, volume) are then detrended: each day a straight line is fitted to the log of the last four years (1,461 days, today included) and the component becomes today's distance above or below that line. Fear & Greed and the rank are bounded, so they are used as they are. Each is then ranked against its own trailing four years; a component joins after two years of history. A pillar is the mean of its components, the index is 100 × the mean of the pillars, published only where at least two pillars exist and smoothed with a trailing 7-day mean. Every step looks backwards only, so a past reading never changes when new data arrive. Why detrend: ranked as raw levels, adoption grew faster than any four-year window can absorb — active addresses rose twentyfold from 2011 to 2015 — so the January 2015 bottom read as hype. Hype beyond price subtracts the trailing four-year percentile of BTC's 90-day log return.
Multiple testing. The lag chart alone runs dozens of correlations; the heat map runs buckets × horizons; Granger runs two directions × several lags. The count is printed above. A single p just under 0.05 among that many is what noise looks like.
