The Bitcoin Barometer is a single 0–100 score that synthesizes eight on-chain, technical, and sentiment indicators into one clear market signal. Instead of tracking a dozen separate data points, investors get one number that tells them whether Bitcoin is in a historically cheap accumulation zone or an overheated danger zone.
This post explains how the Barometer works, how to read it, and what past zone changes have looked like in the market.
Why a Single Score?
Most Bitcoin investors know that indicators like MVRV Z-Score, Puell Multiple, and the Fear & Greed Index exist. Few have the time or expertise to monitor all of them simultaneously, weigh conflicting signals, and make a rational decision.
The Barometer solves this. It aggregates eight indicators into a weighted composite score — so the hard work of synthesis is done before you open the app.
The Eight Indicators Inside the Barometer
The Barometer draws from three indicator categories, each weighted for its contribution to Bitcoin's historical price cycle behavior:
On-Chain Indicators (40% weight)
1. MVRV Z-Score
Compares Bitcoin's market cap to its realized cap (the price at which each coin last moved on-chain). A Z-Score above 7 has historically marked market tops; below 0 has marked bottoms.
2. NUPL (Net Unrealized Profit/Loss)
Measures the total proportion of Bitcoin supply that is currently in profit versus loss. Readings below 25% indicate widespread capitulation — historically a strong accumulation signal.
3. Puell Multiple
The ratio of daily miner revenue to the 365-day moving average. Values below 0.5 reflect mining stress and have historically coincided with macro bottoms.
Technical Indicators (40% weight)
4. Mayer Multiple
Compares the current price to the 200-day moving average. Values below 1.0 mean Bitcoin is trading below its long-term trend — statistically rare and historically advantageous for buyers.
5. Monthly RSI
A momentum oscillator on the monthly chart. RSI below 40 indicates oversold conditions; above 80 signals overheating.
6. Pi Cycle Top Indicator
Tracks the convergence of two moving averages (111-day and 2x 350-day) that have historically signaled market tops within days of their crossover.
Sentiment Indicators (20% weight)
7. Fear & Greed Index
A composite of volatility, momentum, social media volume, and surveys. Extreme fear (below 20) has consistently represented the best risk-adjusted entry points in Bitcoin's history.
8. Google Search Trends
Measures relative search interest for "Bitcoin" globally. Low search volumes during price downturns indicate public disinterest — a contrarian signal that often precedes recoveries.
How the Barometer Score Maps to Zones
| Score | Zone | Signal |
|---|---|---|
| 0–25 | CHILL | Deep accumulation territory — historically low-risk entry |
| 26–50 | COOL | Below average valuation — favorable for dollar-cost averaging |
| 51–74 | WARM | Fair value range — neutral, hold or reduce allocation |
| 75–89 | HOT | Elevated valuations — consider reducing exposure |
| 90–100 | FIRE | Extreme overvaluation — historically precedes corrections |
The Barometer does not predict exactly when price will move. It identifies when the historical probability of positive returns over a 12-month horizon is high or low.
Historical Zone Changes and What Happened Next
January 2023: CHILL Zone (Score: 14)
After the FTX collapse in November 2022, the Barometer dropped to 14. MVRV Z-Score was negative, NUPL sat at 12% (deep capitulation), and the Fear & Greed Index registered 22.
Bitcoin's price 12 months later: +155%.
October 2023: COOL Zone (Score: 32)
As Bitcoin consolidated around $26,000–$28,000 before the halving cycle, the Barometer read 32. Multiple indicators showed below-average valuation without the extreme distress seen in 2022.
Bitcoin's price 12 months later: +187%.
March 2024: WARM Zone (Score: 58)
Post-halving momentum pushed the Barometer into Warm territory. The Mayer Multiple crossed 1.8, Puell Multiple moved above 2.0, and social sentiment indicators surged.
Bitcoin's price 6 months later: -18% (temporary correction before resumption).
December 2024: HOT Zone (Score: 82)
The Barometer reached 82 as Bitcoin approached $100,000. The Pi Cycle Top convergence was accelerating, NUPL crossed 70%, and Google Trends hit a 5-year high.
Bitcoin pulled back ~35% in Q1 2025 from that level.
April 2026: CHILL Zone (Score: 18)
The current reading of 18 reflects a confluence of depressed on-chain metrics. MVRV Z-Score is near 0, NUPL sits at 21%, and the Fear & Greed Index reads 19. All three on-chain indicators are simultaneously in historically favorable territory — a pattern that has occurred only four times in Bitcoin's history, each time preceding a significant bull run within 18 months.
How to Use the Barometer as an Investor
The Barometer is not a trade signal — it is a probabilistic framework for allocation decisions.
In CHILL zones: Historical data suggests increasing Bitcoin allocation systematically. Dollar-cost averaging frequency and size can be scaled up. The probability of positive 12-month returns from CHILL readings above 25 occurrences in Bitcoin's history: 96%.
In WARM zones: Maintain existing positions. Avoid adding significant new exposure at elevated valuations. Monitor for a shift into HOT territory.
In HOT/FIRE zones: Consider reducing exposure incrementally. Not a prediction of an imminent crash — but a signal that the margin of safety is thin and the risk/reward ratio has deteriorated.
The key discipline: let the data determine allocation, not price action, news headlines, or social media sentiment.
The Barometer vs. Individual Indicators
Any single indicator can produce false signals. The value of the Barometer is that it requires multiple indicators to align before generating an extreme reading.
For the score to reach CHILL (below 25), multiple independent data sources — on-chain behavior, technical structure, and sentiment — must simultaneously reflect historically depressed conditions. The probability that all eight indicators produce a false signal simultaneously is significantly lower than the probability that any one indicator misfires on its own.
This is why the Barometer's track record across Bitcoin market cycles has been consistent: it is structurally resistant to noise.
