Is Now a Good Time to Buy Bitcoin?

How to read the Fear & Greed Index

The Crypto Fear & Greed Index (by Alternative.me) scores overall market sentiment on a scale of 0–100. It is calculated daily from six inputs: price volatility, market momentum, social media buzz, Bitcoin dominance, Google Trends data, and surveys.

• 0 – 25 — Extreme Fear — Investors are panicking. Historically one of the most reliable long-term buying opportunities. When the crowd is selling in fear, prices are often near a cycle bottom.
• 25 – 45 — Fear — Market sentiment is bearish. Prices are typically discounted in this range — a decent environment to continue dollar-cost averaging without rushing.
• 45 – 55 — Neutral — Sentiment is balanced. No extreme signal. A steady DCA strategy works well in this range.
• 55 – 75 — Greed — Investors are getting excited. Avoid rushing in with large new positions — wait for a pullback before increasing allocation significantly.
• 75 – 100 — Extreme Greed — The market is euphoric. Historically this has preceded corrections. Avoid large new positions — wait for sentiment to cool before adding significantly.

Warren Buffett's rule applies directly: "Be fearful when others are greedy, and greedy when others are fearful." Use the index as a sentiment gauge, not a precise timing tool.

How to read the AHR999 Indicator

AHR999 was designed by a Chinese Bitcoin investor specifically to help dollar-cost averaging (DCA) buyers decide when to increase or reduce their purchases. It multiplies two ratios together: (current price ÷ 200-day geometric mean price) × (current price ÷ power law fair value). The result is a single number that captures both short-term momentum and long-term valuation.

• Below 0.45 — Fire sale. Bitcoin is deeply undervalued on both measures simultaneously. Every time this zone was reached historically, the following 12–24 months delivered exceptional returns.
• 0.45 – 1.2 — DCA zone. Bitcoin is fairly priced relative to its trend. The ideal environment to accumulate steadily without rushing.
• Above 1.2 — Overheated. Bitcoin is trading above its power law fair value. Consider slowing or pausing new purchases until the indicator cools.

The dashed lines on the chart mark the 0.45 and 1.2 thresholds so you can see how often past cycles entered each zone.

How to read the Mayer Multiple

The Mayer Multiple is simply today's Bitcoin price divided by its 200-day moving average (200DMA). The 200DMA is one of the most widely watched trend indicators in finance — when price is above it, the market is bullish; when below, bearish. The Mayer Multiple quantifies exactly how far above or below that line the price currently sits.

• Below 1.0 — Price is under the 200-day average. Long-term holders who bought in this zone have consistently seen strong returns over the following 12–24 months.
• 1.0 – 2.4 — Normal historical range. No extreme signal. Continue your regular DCA plan.
• Above 2.4 — Fewer than 4% of all trading days in Bitcoin's history have been above this level. Each time it was breached, a significant correction followed within months.

Trace Mayer suggested that buying when the multiple is below 2.4 and accumulating aggressively below 1.0 is a reasonable long-term strategy. The blue and red dashed lines on the chart mark those key thresholds.

How to read the 200-Week MA

The 200-week moving average (200WMA) is the average Bitcoin closing price over the last ~1,400 days — roughly 3.8 years. It moves very slowly and represents Bitcoin's deepest long-term trend. This indicator shows how far, in percentage terms, the current price sits above that baseline.

Why it matters: Bitcoin has never closed a weekly candle below the 200WMA and gone on to new cycle lows without eventually recovering decisively. Every time the price approached or touched this line, it marked a generational accumulation opportunity. Conversely, the further price extends above the 200WMA, the closer a cycle top historically becomes.

• Below 0% — Price is under the 200WMA. Has only happened a handful of times. Always recovered.
• 0% – 100% — DCA Zone. Price is near its long-term anchor. The ideal zone to dollar-cost average steadily without rushing.
• 100% – 300% — Mid-Late Cycle. Depending on other indicators: continue DCA, hold steady, or consider reducing exposure.
• Above 300% — Euphoria Zone. Price can still go higher, but every prior cycle that reached this zone corrected significantly. Consider taking some profits.

How to read the Rainbow Chart

The Rainbow Chart overlays Bitcoin's price history on a logarithmic regression model fitted to data going back to 2009. On a log scale, Bitcoin's price growth has traced a remarkably straight line over time. The colored bands are fixed multiples of this trend line — they don't shift based on recent price action, which makes them a stable long-term reference.

When price dips into the blue/indigo bands at the bottom, Bitcoin is trading well below its historical growth trend — a zone that has consistently rewarded patient buyers. When price climbs into the orange and red bands at the top, the market is in late-stage euphoria territory, and past cycles have seen sharp corrections follow.

The dashed future extension shows where the bands will be in coming years if Bitcoin's logarithmic growth trend continues — not a price prediction, but a projection of what "fairly valued" would look like over time. Use the timeframe buttons above the chart to zoom into the last 2 or 5 years, or view the entire history.

Important: The Rainbow Chart is a model, and all models have limits. Bitcoin could eventually break its long-term log regression upward or downward. Use it as one signal among several, not as a guarantee of future price behaviour.
