From the 4-hour chart, Bitcoin has been continuously declining since the previous high point, with a very clear downtrend. The candlesticks are mostly bearish, with occasional long lower shadows, but these are just short-term buying attempts and do not change the overall bearish pattern. In the early morning, Bitcoin faced obvious resistance at 68,500. During the rebound, trading volume was lacking, and the momentum was weak, with significant resistance above. The subsequent strategy is to stay cautious on the short side!
