Some people questioned the short selling at 956. It is actually a good deal. Calculate the profit and loss ratio yourself. I will not hit the high point of 973. That is, the stop loss is 1700 points. The profit of exchanging the daily line track. Even if the daily line track is 85, there will be 10,000 points of profit. In plain words, 1700 for 10,000. Do you want to take the risk? The essence of trading is position management. The second is the profit and loss ratio. The third is to look at the general direction. Otherwise, the second point is useless. So in general, I will increase my position only if it is feasible. That's all! $BTC
