Bitcoin and Ethereum Evening Trading Suggestions and Future Trend Analysis: 12/30 Currently, the market is in a typical range-bound pattern, with prices oscillating between key support at 84,408.6 and resistance at 90,000. Momentum is weakening, and market sentiment is becoming more balanced. Technical indicators show that short-term moving averages are trending upward, providing some support signals, but the entanglement of moving averages and insufficient trading volume limit the possibility of trend development. Meanwhile, the bullish engulfing signals appearing in the candlestick patterns have some reference value, but their significance is moderate and not enough to change the current oscillation pattern. Given the current market is in a range-bound state, there is a high-probability opportunity to sell near the strong resistance at 90,000, and the limited trading volume restricts the possibility of a breakout. Therefore, shorting near resistance is a reasonable choice aligned with the current market condition. Xiao Ma's evening trading suggestion is mainly to go short at high levels.
