$BTC From the current market perspective, Bitcoin has formed a long bottoming tail pattern in the 4-hour chart, which is a core signal of a strong bullish counterattack. The short-term market structure has fundamentally reversed! During the pinning process, the buying pressure below is particularly strong; this is not passive stabilization but a clear action of active accumulation by the main funds. After that, the price quickly surged and remained firmly above the key support level, with the K-line body growing larger. This not only shows that the bulls firmly control the market but also indicates that they have seized the trend leadership and have enough momentum to drive the market upward continuously. More critically, this long tail pattern happens to appear in the core support zone of the long-term upward channel, where the lower moving average system has formed multiple supports, and the middle band of the Bollinger Bands has also turned upward. The price shows a healthy upward rhythm of 'slowly rising lows and continuously breaking through highs.' In terms of operation, it is recommended that everyone rely on the key support level, mainly focusing on low buying, with high shorts only as a supplementary measure $ETH .
