Market Sentiment Scores

The following are independent scores representing the strength of each trend observed in the chat on the target day, on a scale of 0 to 100. They are not probabilities, composition ratios, or deviations from historical averages, and they do not add up to 100.

Bullish and bearish sentiment, uncertainty, and attention can all be high at the same time. Please interpret each item as a separate observation axis.

Community Sentiment Scores

These are sentiment trends observed from the chat as a whole. Each item is independent and does not add up to 100.

Coin-Specific Signals

BTC

• Chat directional hypothesis: Downward

• Observations supporting the judgment: Multiple downward views such as "it will go down infinitely" and "from year-end to March, down" appeared several times / Bearish comments such as "12.2 million is the top" and "will it drop to 4 million?" were seen / Topics about entering from shorts or selling, rather than longs, stood out
• Observations weakening the judgment: There was also one bullish remark such as "Go long!" / Price forecasts may have included jokes and hype, which weakens the directional signal

ETH

• Chat directional hypothesis: Direction unclear

• Observations supporting the judgment: There was a remark saying, "I just bought ETH three days ago"
• Observations weakening the judgment: Almost no directional discussion about ETH was seen / It is difficult to confirm any sustained discussion of coin-specific trading judgments or price forecasts

Concentration of Attention by Coin

BTC attention concentration was high at 63 / 100, while ETH attention concentration was only 18 / 100. Topic composition was centered on cryptocurrency topics, with a fair amount of daily casual chat mixed in. Stocks accounted for 12 / 100, FX for 6 / 100, and macroeconomics for about 4 / 100.

AI Analysis

For BTC, expressions such as "down infinitely," "down from year-end to March," and "top" appeared multiple times in the chat, making a bearish interpretation relatively easy. That said, some of the remarks may have been hype or jokes, so they do not necessarily reflect a definitive view of all participants.

For ETH, only about one individual trading report could be confirmed, and coin-specific discussion was thin, so the direction was not clear. At the community level, rather than strong buying appetite, a stance of waiting for a bounce and mild caution was more dominant.

As for market pressure, the ordering of price pressure score: 42 / 100, bullish trend score: 46 / 100, and bearish trend score: 58 / 100 shows that the picture was not clearly one-sided. At present, the interpretation is that a cautious mood centered on BTC may be leading in the short term, but confidence is not high.

Future Validation Candidates

• The relationship between concentration of posts in the 19:00 hour and subsequent market moves
• Subsequent reactions on days when bearish comments about BTC increased
• The relationship between price action and days when short-biased sentiment intensified
• Changes in market sentiment on days when stock- and lifestyle-related topics are mixed in

These are candidates worth verifying in future comparisons with historical data. In particular, the combination of concentrated mentions of BTC and a bearish tone may be related to subsequent volatility and the mindset of selling into rebounds.
