How to Read These Indicators

A quick explainer on what each indicator measures and how to use it.

The Crypto Fear & Greed Index (by Alternative.me) measures overall market sentiment on a scale of 0–100. It's calculated from volatility, market momentum, social media, surveys, dominance, and trends.

How to use it: Extreme Fear (0–25) historically marks excellent buying opportunities — when everyone is panicking, prices are often at or near a bottom. Extreme Greed (75–100) signals caution — markets tend to correct after euphoric periods. Warren Buffett's famous quote applies: "Be fearful when others are greedy, and greedy when others are fearful."

AHR999 was created by a Chinese Bitcoin investor to help DCA (dollar-cost averaging) investors decide when to buy. It combines two ratios: the current price vs the 200-day geometric mean, and the current price vs the power law "fair value" estimate.

How to read it:

  • Below 0.45 — Fire sale. Bitcoin is significantly undervalued. Historically the strongest accumulation zone.
  • 0.45 – 1.2 — Good to DCA regularly. Bitcoin is fairly priced relative to its trend.
  • Above 1.2 — Overheated. Bitcoin is above its power law fair value. Consider slowing purchases.

The Mayer Multiple (created by Trace Mayer) is simply the current Bitcoin price divided by its 200-day moving average. It gives context to whether Bitcoin is cheap or expensive relative to its recent trend.

Key thresholds: Below 1.0 means price is below the 200-day average — historically a strong buy signal. The 2.4 threshold is the key level to watch: fewer than 4% of all Bitcoin trading days have ever been above 2.4x. When the Mayer Multiple exceeds 2.4, the risk of a correction increases significantly.

The 200-week moving average is the average Bitcoin price over the last ~1400 days (~3.8 years). It's the ultimate long-term trend anchor — moving slowly and rarely deviating far from Bitcoin's growth trajectory.

Why it matters: Bitcoin has never closed a weekly candle below the 200-week MA and gone on to new lows (historically). Every time the price has approached or touched this line, it marked a generational buying opportunity. The further the price gets above it, the closer a potential market cycle top.

The Rainbow Chart overlays Bitcoin's price on a logarithmic regression model of its growth since 2009. Each colored band represents a valuation zone, from deep blue (extremely undervalued) to dark red (maximum bubble).

The model is based on the observation that Bitcoin's price, on a log scale, has grown in a straight line over time. The colored bands are multiples of this trend line. When price dips into the blue bands, history suggests it's a good time to accumulate. When price enters the red bands, the market is likely in euphoria.

Important: The Rainbow Chart is a model. Models are always wrong eventually. Use it as one signal among many, not as a certainty.
