Looking at this K-line chart trend, I will analyze the recent market logic.

**Bitcoin's Rebound Story**

The price bottomed out at a low of 89268.0 and has started to rebound. It has now risen to around 91349.9. During this process, multiple technical indicator lines have turned upward simultaneously, clearly indicating that the bulls are dominating in the short term. The previous sustained downtrend has been broken, with consecutive red candles and a breakthrough of key indicator lines, showing that the buying momentum is gradually being released.

However, it is important to note that during the rebound, there will likely be pullbacks for confirmation. After a sharp rise, some consolidation is a normal rhythm. Whether it can truly stabilize in the medium term still requires further observation, especially whether it can break through those critical resistance levels.

**Analysis of Another Cryptocurrency's Trend**

A similar logic applies to another coin. The price quickly rebounded from a new low of 3052.48 and has now risen to around 3141.05, forming a long red candle. Indicators are also rising in sync, temporarily easing the bearish pressure, and the bullish oversold rebound has begun.

The downward momentum from earlier has basically been exhausted at the low point. The rebound also broke through the key resistance line at 3119.7, indicating that the bulls' counterattack is not weak. But for this to develop into a sustainable upward trend, it still depends on whether it can hold steady at critical levels after the rebound.

**Specific Support and Resistance Levels**

For this coin, the first support is at $3080 (the consolidation platform during the recent rebound), with a strong support at $3050 (an important stabilization point after the low). If it falls below 3050, the rebound trend may quickly reverse, and a reassessment of the market will be needed.

On the resistance side, the first resistance is at $3140 (current price + previous consolidation resistance zone), with a strong resistance at $3180 (indicator line suppression + previous rebound high during the decline). If it can break through 3160, the upward space for the rebound may extend toward 3180.

**Reasonable Trading Strategies**

The short-term approach is quite clear: focus on buying during pullbacks. Specifically, if the price falls back to the $3080-$3060 range and stabilizes, consider entering long positions with a stop loss below $3040. This setup helps to better control risk.

Conversely, if the rebound encounters resistance between $3141-$3180 and volume candles show a bearish engulfing pattern, you can try a small short position, with a stop loss above $3185, targeting around $3100. This strategy is suitable for traders with some experience, as it requires quick judgment and reaction.

The trading approach for Bitcoin is similar. Short-term, buying on pullbacks is the main rhythm. If the price falls back to the support zone of $91000-$90099.1 and stabilizes, consider entering long positions with a stop loss below $90000. If the rebound faces resistance between $91600-$92300, you can try a small short position, with a stop loss above $93000, targeting around $90500.

Overall, the current market signals are quite clear. The key is to respect support and resistance levels, implement good risk management, and avoid overtrading.
