Bitcoin is showing a generally oscillating upward trend, starting to rebound from a low of around 89,866 in the early morning, with intra-day fluctuations and a steady climb, reaching a high of 91,597. The rebound is steady and orderly. Ethereum's movement is highly correlated with Bitcoin, starting its upward trend from a low of 3,096, rising to a high of around 3,160, displaying a clear pattern of following the rally throughout, with strong market linkage.

The daily chart's upward channel continues to extend, and after experiencing a prior weak pullback and completing sufficient accumulation and bottoming, the market has successfully shifted to a steady oscillating upward rhythm. Bullish momentum is being released in an orderly manner, simultaneously driving the moving average system to resonate upward, indicating that the market trend has clearly returned to a bullish dominance, with this trend showing strong sustainability and structural stability. The four-hour chart continues its strong upward trend, with prices steadily climbing along the upper boundary of the channel, presenting a one-sided strong upward technical pattern, further solidifying the foundation for the daily trend. From the current market rhythm, bullish forces are still accumulating, and short-term pullbacks are not signs of trend reversal but typical consolidation actions aimed at digesting profit-taking and clearing out weak hands, thus accumulating energy for further upward movement. The early trading strategy continues to focus on pullback-based long positions, aligning with the current bullish market pattern.

Specific trading suggestions: Pay attention to the support levels at the two zones of 89,500-90,300 and 88,800-88,150. If support holds, consider attempting low positions accordingly, with potential upside of 500-5,500 points.
