After the price bounces off the first support level at night, unfortunately, the rebound lacks strength. Today, pay attention to the top and bottom of the 4-hour horizontal range. Only a breakthrough above the horizontal range top at 84585 will allow for further upward movement. The upper resistance levels to watch are around 85575-86600-87700! If today it breaks below the bottom of the horizontal range at 83535, the market will continue to decline. The lower support levels to watch are around 82515-81115-79900! (If it does not break the top and bottom of the horizontal range, it will continue to consolidate sideways.) #BTC走势分析
