What is Bitcoin Misery Index?
The Bitcoin Misery Index (BMI) is a contrarian sentiment indicator designed to help Bitcoin investors gauge market sentiment. It ranges from 0 to 100, where lower values signal "misery" and suggest strong buy opportunities, while higher values indicate optimism and potential sell signals. Developed by Tom Lee of Fundstrat Global Advisors in 2018, the index relies on Bitcoin's price action rather than fundamental analysis to determine investor sentiment.
Understanding the BMI can be crucial for your trading strategy, as it helps to identify shifts in market sentiment that may not immediately be apparent from price charts alone. The index updates daily at 6:30 PM EST, providing a timely snapshot of investor feelings regarding Bitcoin's performance.
- Low BMI (below 27) indicates strong buy opportunities.
- Neutral BMI (around 50) suggests balanced sentiment.
- High BMI (above 67) points to potential sell scenarios.
Key Characteristics
The Bitcoin Misery Index is characterized by its unique calculation method, which includes two primary components: win-ratio and upside less downside volatility. The win-ratio measures the percentage of days Bitcoin's price closed higher, while the upside less downside volatility assesses the difference between upward and downward price fluctuations.
The formula for calculating the BMI is straightforward: \( 7 \times (z\text{-score of win-ratio} + z\text{-score of upside less downside volatility}) + 50 \). A score of 50 represents neutral sentiment, indicating neither extreme optimism nor pessimism. This makes the BMI a valuable tool for identifying market extremes.
- Win-ratio: Higher percentages indicate better performance.
- Volatility measurement: Greater differences between upward and downward movements signal stronger sentiment.
- Daily updates: Keeps investors informed with the latest sentiment data.
How It Works
The Bitcoin Misery Index operates by quantifying investor sentiment through its unique components. When the BMI falls below 27, it indicates widespread dissatisfaction among Bitcoin holders, which can often precede significant price rallies. Conversely, when the index rises above 67, it suggests excessive optimism, signaling a potential market correction.
This contrarian approach mirrors traditional market indicators and can help you make informed trading decisions. For instance, understanding when to buy or sell based on BMI readings allows you to capitalize on market inefficiencies.

Examples and Use Cases
Historical data illustrates the effectiveness of the Bitcoin Misery Index. For instance, in December 2013, the BMI hit 100, indicating peak happiness among investors. Shortly after, Bitcoin's price reversed course dramatically. Similarly, following the lows of 2018, the BMI fell below 27, which preceded significant price rallies.
Here are some notable examples of BMI readings and their implications:
- December 2013: BMI at 100, followed by a price drop.
- Post-2018 lows: BMI below 27 led to major upward price movements.
- Contrarian signals: Levels below 27 often mark market bottoms, while those above 67 indicate tops.
Important Considerations
While the Bitcoin Misery Index is a powerful tool, it’s essential to consider its limitations. High volatility in the cryptocurrency market can make BMI signals challenging to interpret, and relying solely on this index may not yield successful trading outcomes. Therefore, it is advisable to use the BMI in conjunction with other analytical tools.
