From the 4-hour chart, Bitcoin has completed the bottom rebound pattern. The hourly chart is gradually showing a staircase-like rise, and the current price has held above the lower support line. The key is still to closely monitor whether the lower support area can be maintained— as long as it does not effectively fall below the previous level, the overall direction remains bullish. The short-term target to follow is the price range of 90000-92000.
