A time-based analysis has been conducted on the Bitcoin chart in the four-hour timeframe. In this method, it is expected that the price reacts upon reaching any of the vertical lines drawn on the chart. Specifically, if the price trend before the vertical line is upward, it is likely, with over 70% probability, to shift to a downward trend after touching the vertical line, and vice versa. The method used to draw these time-based lines is innovative, and related educational materials will be provided in the future.
