Bitcoin tested the 105800 line yesterday and was once again pressured to drop, hitting a low around 100700. On the daily chart, the candlestick shows consecutive bearish patterns with a significant decline, and after this sharp drop, there has not been a quick rebound. The same is true on the four-hour chart; after a night of market digestion, although there was a halt in the decline, the downward trend has been established. The overall structure remains weak, so in the short term, we will focus on short positions, with attention on the 104200~103500 range above.
