According to BlockBeats, on September 27, top trader Eugene Ng Ah Sio posted on social media that seasonality is often an important factor in determining animal spirits.

As the end of September approaches, the market has never seen a situation where the market rose in September and closed down in October since the birth of BTC. In the previous 11 years, BTC closed down only twice in October, which had nothing to do with the price action in September.

This data point by itself means nothing, but if enough people interpret it as a buy signal, then the self-fulfilling prophecy can spread quickly.
