Bitcoin shows a pattern of oscillating consolidation with a slight upward trend. It started to rebound from a low around $90,245 early today, testing the high near $91,191 during the oscillation and climbing, currently trading around $90,945, up 0.33% for the day. Ethereum's movement remains highly correlated with Bitcoin, simultaneously beginning a recovery from lows, demonstrating a steady upward trend throughout, with the market showing continued signs of synchronized movement.

On the daily chart, the price remains within the upward channel formed since December 24, supported effectively at the psychological level of $90,000. Although bullish momentum has weakened compared to earlier, the moving average system has not yet shown signs of reversal, and the short-term trend still favors the bulls. The four-hour chart continues to show a oscillating but slightly bullish pattern, with a bullish candle with a lower shadow exceeding half of the body appearing early this morning, indicating strong buying support at the support level. The price has steadily risen along the lower boundary of the channel, further solidifying the short-term bullish foundation. The current market rhythm suggests that although bullish power has not continued to expand, support levels have been tested multiple times and quickly recovered, with short-term pullbacks not indicating trend reversals but typical consolidation actions to build momentum for a subsequent breakout above the resistance at $93,161. Today's trading strategy remains focused on retracement-based long positions, paying close attention to the effectiveness of the $90,000 support level. If it falls below $89,500, caution is advised for a potential trend reversal.

Specific trading suggestions: Monitor the support levels at $90,500-$89,800 and $89,300, $88,000. If these hold, consider attempting a long position with a target of 500-6000 points higher. If the $90,000 level breaks downward, watch for further support at $89,300; if that breaks, look toward $88,000. Overall, the decision should be based on the trend breakout situation.
