How is Bitcoin market sentiment calculated?

Bitcoin market sentiment is calculated using a proprietary NLP model analyzing over 1,000 sources, including social media, news outlets, regulatory filings, and developer activity, scaling from 0 (Extreme Fear) to 100 (Extreme Greed).

What does a high Bitcoin Fear and Greed Index indicate?

A high Fear and Greed Index (above 70) indicates Greed or Extreme Greed: positive, euphoric coverage dominates the conversation. A low index (below 30) indicates Fear or Extreme Fear: negative coverage dominates. The reading describes the tone of coverage on that day.

How often is the market sentiment data updated?

The sentiment metrics are updated in real-time, aggregated daily, and compiled monthly to provide clean historical sentiment trends for digital asset traders and researchers.

How far back does the Bitcoin sentiment data go?

Daily sentiment data is available from February 2018. The index has been computed live since January 2023; values for earlier dates are calculated from Perception's archived article corpus using the same formula. Source volume grows over time, from roughly 40-90 scored articles per day in 2018 to 1,500+ per day today, and each day's article count is published alongside its score.
