Market Sentiment Scores

The following are independent scores representing the strength of each tendency observed in the chat on the target date, on a scale of 0 to 100. They are not probabilities, composition ratios, or deviations from historical averages, and they do not have to sum 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 the sentiment tendencies observed from the entire chat. Each item is independent and does not sum to 100.

Asset-Specific Signals

BTC

• Chat-based directional hypothesis: upward

• Observations supporting the judgment: There was a remark indicating upward movement, 'BTC HH!!' / Bullish-leaning reactions were seen, such as 'Bitcoin feels like it's not much at this level' / 'Alright! Nice, nice! Looking forward to seeing how far it goes up' shared expectations for further gains / There was caution about FOMO, but overall expectations for upside were dominant
• Observations weakening the judgment: There was a warning statement: 'Beware of FOMO' / Short-term remarks showing a wait-and-see stance and uncertainty were also mixed in / Conversation was dispersed into topics other than BTC, so the directional view was not unanimous

ETH

• Chat-based directional hypothesis: effectively not observed

• Observations supporting the judgment: No clear observations
• Observations weakening the judgment: No clear observations

Market Sentiment

In the chat overall on this day, interest in price movement was high, with a price pressure score of 61 / 100, bullish sentiment score of 58 / 100, and bearish sentiment score of 32 / 100. The panic sentiment score of 12 / 100 was low, and there was no sign of excessive panic. Meanwhile, the overheating/euphoria score was 42 / 100, directional uncertainty was 57 / 100, and chat attention level was 78 / 100, indicating strong interest but divided conviction.

For BTC, the reception pointing to an upward move was dominant. There were remarks such as 'BTC HH!!' and 'Looking forward to seeing how far it goes up,' so the bullish sentiment score is relatively high. However, there was also caution such as 'Beware of FOMO,' so the view was not overly one-directional.

Posting Conditions

There were 441 posts and 18 unique participants. The first post was at 00:06:28 and the last post was at 23:07:39. Posting peaked in the 21:00 hour (103 posts, 23.4%), the 11:00 hour (60 posts, 13.6%), and the 22:00 hour (47 posts, 10.7%), with especially strong concentration in the 21:00 hour. The parsing success rate was 100%.

In terms of activity, casual conversation continued from late night into the morning, then during the day stocks, monetary policy, crypto regulation, and disasters and housing topics were interwoven, before conversation volume increased again at night. Even with a small number of participants, repeated posting was common, and thread-like conversation stood out.

Notable Topics

• BTC: Coexistence of upside expectations and FOMO caution
• FOMC and interest rates: Interest in the meeting and outlook
• Japanese stocks: SoftBank Group, Koei Tecmo, the Nikkei, TOPIX
• Crypto regulation: Interest in yen-denominated spot indices and separate taxation
• Geopolitics, disasters, and housing: Topics spread widely beyond markets

In terms of asset concentration, BTC mentions were the most prominent, but sustained concentration on ETH or other altcoins was difficult to confirm on this day. Rather, the notable feature was that stocks and macro topics outside crypto were running in parallel.

AI Analysis

From the comments of chat participants, this day contained both 'upside expectations for BTC' and 'caution about short-term overheating' at the same time. Rather than leaning into buying with strong conviction, this suggests a state of awareness about upside room while also worrying about external events and short-term pullbacks.

Also, because interest in FOMC, monetary policy, domestic stocks, semiconductors, and regulation was broadening, the community's attention was not on crypto alone but on the wider financial market. Days like this may later turn out to mark a shift in market sentiment, so they are worth validating in the future.

In the short term, interest in BTC is somewhat upward-leaning, but because the center of conversation is dispersed, it is not suitable for a strong trend call. Rather, it is natural to view it as a state where upside expectations remain while waiting for catalysts.

Future Validation Candidates

• Whether posting concentration in the 21:00 hour relates to subsequent volatility
• Whether days when bullish BTC comments coexist with FOMO caution tend to become turning points
• How the share of crypto versus interest-rate and FX topics changes around FOMC
• Whether days with more discussion of stocks and macro than crypto indicate a shift in capital attention
• Whether regulation and tax-related topics move in tandem with BTC attention concentration
