BTC is again encountering resistance near 69,000 within the 12-hour downtrend channel. The upper channel boundary exerts significant resistance, and the overall bearish structure has not changed. The main trend still maintains the core strategy of "rebound and short." Focus on resistance levels around 67,800-68,000 during the day. If the price rebounds to this area and faces resistance then falls back, consider short positions with short-term support around 66,200. If broken, look further down to 64,700. Strict stop-loss settings are required for operations. Until the rebound can effectively break through resistance, avoid blindly chasing longs.
