Bitcoin maintained a volatile rhythm today, and the price rebounded quickly after stepping back on key support in the morning. Entering the European session, the price momentum has weakened, and the market sentiment has gradually turned cautious. In the evening, the price fell under pressure after hitting a high level, and we synchronously prompted the short order layout to accurately capture the callback band again. On the whole, the long and short rhythm switching is smooth, the intraday trading opportunities are clear, and the breakthrough and retracement of key points have verified the effectiveness of the technical side.

From the current market observation, Bitcoin's short-term upward momentum has been weak, and the 1-hour level has continuously closed a number of long upper shadow K-lines, indicating that the upper selling pressure is gradually increasing. Despite several attempts by bulls to the upside during the day, the price has not been able to gain a foothold in the key pressure zone, instead forming a local top structure after repeated tests. In addition, the volume is showing signs of contraction, and the market's willingness to follow up is insufficient, further suggesting short-term adjustment demand. It is expected that from midnight to the early morning of the next day, the market is likely to continue the pullback trend, and the operation can wait for the price to rebound to the pressure area near the layout of short orders in batches, and the target is to look at the lower support band. It is necessary to be wary of sudden intraday rebounds, and it is recommended to strictly control positions and set reasonable stop losses. If the volume falls below the support during the pullback, it may open up a deeper downside. The short-term market is still dominated by shock repair, and high-altitude participation needs to remain flexible and lock in profits in a timely manner.

Short-term trading suggestions:
Bitcoin is short around 85500, with a target focus around 83000; Ethereum is short around 1640, with a target focus around 1580.
