Mr. Coin in the crypto world: 2.23 Bitcoin (BTC)) market analysis reference. The short-term trend of Bitcoin remains weak and oscillating. Yesterday’s gains have begun to slowly retreat, but as long as the short-term key support at 66,000 has not been broken, the oscillation pattern will not change. Therefore, Mr. Coin recommends mainly short positions on rebounds. The 4-hour chart shows consecutive bearish candles breaking below the EMA7 moving average (67983→67642), indicating weakening short-term bullish momentum; simultaneously, the 4-hour MACD indicator’s DIF (92.2) crosses below DEA (49.6), with decreasing histogram volume, further confirming short-term weakness. However, support below remains clear: on the daily chart, a long lower shadow was formed on February 20 (66280→68318), indicating significant buying interest around the 67,500 area, and the current price is testing the critical support near the 4-hour EMA30 (67000). Although the daily MACD still shows a death cross, the green histogram has narrowed, and the bulls and bears are entering a critical phase of contention. It is expected that the oscillation and consolidation will continue for some time. Traders can wait for a breakout of the 66,000-69,000 correction zone for clearer market direction. Short-term reference for 2.23 Bitcoin: short at 68,500-69,500, with a stop loss at 71,500 and a 500-point loss limit, targeting below 67,500; long at 66,500-65,500, with a target above 77,500 and a 500-point stop loss.
