On the daily timeframe, price has already broken through the key support level of 74,000, currently trading below the middle band of the Bollinger Bands, and has formed a typical "dark cloud cover" pattern, which is a strong bearish reversal signal. Meanwhile, the MACD indicator has also turned into a death cross, clearly indicating that bullish momentum is nearly exhausted, and the market trend may face further corrections.

Shifting focus to the four-hour timeframe, after piercing the important psychological level of 70,000, price is exhibiting weak consolidation near 69,000. Observing the moving average system, we can see that the moving averages are in bearish alignment, which further confirms that bearish forces have gained the upper hand in the market. Based on the above analysis, the recommendation is to trade rallies with short positions as the primary strategy.
