Bitcoin tested the 76,000 resistance level in the morning without success and then experienced a pullback. From the four-hour chart, the KDJ crossover is moving downward, and the MACD bullish momentum is decreasing. On the one-hour chart, a sharp top pattern has already formed, and the current price has broken below the middle support of the Bollinger Bands. At present, the Bollinger Band midline has completed a small-scale support and resistance line reversal. In the afternoon, focus on the 73,800 range. If it breaks below earlier, subsequent pullbacks will be more smooth.
