BTC is experiencing severe fluctuations, and chasing after highs and lows in wide oscillations can easily lead to losses. The long positions set in the 90000-91000 range previously need to be monitored for confirmation of the midnight closing: if it effectively breaks below 90000 key support, it is recommended to exit long positions, and subsequently watch for rebound opportunities in the 86000-88000 range to replenish positions; if the price stabilizes above 90000 again, one can participate in the trend, with the upper target resistance level looking towards 94000 nearby. #BTC走势分析
