☀️ 3D Integrated Trading System | BTC Market Early Bus ——The four hour long position can double in volume, and the signal of upward reversal is strengthening. The current price is around 83K. Last night, the four hour long position suddenly doubled in volume, marking the first sustained increase in buying volume in the past week. This is not a single pulse of short covering, but a proactive attack by bulls. 1. Long and short positions: The bulls have finally taken action. The bullish volume can double, breaking the previous deadlock of "neither falling nor rising". Bulls are actively entering the market. However, there was significant selling pressure near 83K, which briefly surged to 83062 and then fell back to 81678 during trading, indicating that selling still exists above. From the fluctuation curve of long and short positions in the past two months, it can be seen that bulls have taken the initiative. 2. On chain data: The four supporting logics remain unchanged. Medium sized whales (10-10000) have cumulatively increased their holdings of approximately 88987 BTC in the past month, with a total holdings of over 13.69 million BTC, reaching a six-month high. The cost line of the new giant whale is around 77K, and the current price is about 6.7% higher. This group of people still have a floating profit buffer. BlackRock saw a single day inflow of $665 million yesterday, setting a record high since 2026, but only IBIT was buying, while Fidelity and Grayscale were selling out. The BTC reserves on the exchange are continuously decreasing, and there are fewer and fewer chips available for sale. Macro bearish sentiment has repeatedly bombarded, and 80K has never been effectively breached. Whether it should fall or not is already a strong signal. 3. Structural form: 83K is short-term resistance, 80K is bottom line. The BTC price has reached the end of the daily decline triangle, doubling in volume in four hours, and the window for change is opening. BTC oscillates within the range of 81.6K-83.5K. Above 83K-83.5K is short-term resistance, and after breaking through, it looks high to around 88K. Xiaolong's core judgment: The four hour increase in volume is the most important change today. The four logics of Whale's fundraising, BlackRock's inflow, the decrease in exchange reserves, and the inability to break through 80K all point in the same direction: the probability of an upward trend is increasing. If rejected, continue grinding at 81K-83K. Don't chase too much, wait for the confirmation signal of the 83K volume increase. The change is brewing, and once it goes up, the target is around 84K-84.5K, or even 88K. Choose a low point and get in BTC!
