Gu Jingci: Bitcoin/Ethereum traded sideways on August 17th; a rally is likely to be followed by a pullback.

Bitcoin/Ethereum broke through 63500 and 1900 in the early morning but has remained in a sideways consolidation, with multiple attempts to break higher failing and showing significant resistance. Previous highs of 1920-1930 and the area around 64000 still present resistance; without a significant breakout at these levels, the trend is likely to continue its downward correction. The four-hour chart shows multiple long upper shadows and repeated attempts to break higher followed by pullbacks, suggesting a continued bias towards shorting on rallies. The weekly chart shows the middle Bollinger Band forming a significant short-term resistance level, which has been repeatedly tested but failed to hold. Evening trading suggestions: Bitcoin: Short at 63600-64000, target 61000-62000; Ethereum: Short at 1905-1920, target 1800-1840, with further targets at 64500 and 1940.
