BTC has experienced a pullback, with the 4-hour level showing weakness and consolidation after breaking through the 70,000 level, while the daily level has shown signals such as a dark cloud cover. Although short-term bearish momentum appears dominant, the trading volume has not expanded significantly during this pullback, suggesting it's a technical adjustment rather than a trend reversal.

Currently, there's a tug-of-war between bulls and bears around the 70,000 key level. The outcome at this position will determine the subsequent direction. In the short term, watch closely if it recovers above 71,500, which could ease current downward pressure. If it fails to break through, it may further test the 67,000 - 68,000 range.
