As can be seen in the chart, BTC has shown a downward trend, and the price is close to the Vegas support level and the important support line, so the size of BTC breakthrough energy is very important. The strength of short energy can be seen from MACD, and the line segment is about to break through the central axis. In the short term, I think there will be a small rebound in prices and then continue the short-selling trend. The profit margin is huge, and now it is a good shorting position.
