Bitcoin's current price is experiencing a strong upward trend around 89,200. From the 4-hour timeframe, the moving average system has formed a typical bullish alignment—EMA5 is at 88,186, EMA10 is close behind at 87,954, EMA20 is at 87,738, and EMA120 is at 87,572. This setup indicates that the short-term moving averages are fully diverging upwards, with the price consistently staying above all major moving averages, suggesting a fairly stable upward trend.

The MACD indicator is currently in a strong golden cross state, with the DIF value reaching 100.3, far above DEA's -19.2. The green histogram bars continue to expand to 240, indicating very strong and accelerating upward momentum. Regarding Bollinger Bands, the price has broken above the upper band (88808), moving within a strong upward channel. The widening of the bands shows increasing volatility.

The RSI data also supports this judgment. RSI1 has entered the overbought zone at 81, while RSI2 and RSI3 are at 67 and 57 respectively, indicating overall bullish strength. The K and J values in the KDJ indicator are 71 and 90, respectively. Although these suggest overbought conditions, the D value is relatively low at 61, and the three lines diverging upwards provide room for further gains.

Based on these signals, the main strategy is to go long. You can choose to build positions gradually around 88,000-87,700 in the 4-hour middle band during pullbacks, or wait for a breakout above the previous high of 89,368 for a lighter follow-up. For targets, the first phase focuses on 90,100 ( corresponding to the EMA200 level ), and the second phase can aim for 91,400 ( EMA250 level ).
