On the day, the 4-hour Bitcoin K-line showed a continuous downward trend, with the price breaking below the trend line and falling to the integer level of $85000, followed by a slight rebound forming a long lower shadow. Previously, $87786 had become a key resistance level. Currently, it is overall in a downward trend, and there are no obvious signs of divergence to stop the decline, still in the process of a wave of downward movement at the 4-hour level.
