Short selling still requires weak ETH. Yesterday, it was mentioned that if it wants to rise, it must break through the 1820 level. Yesterday, it surged to 1838 and then fell significantly without any upward momentum. However, for safety reasons, I waited until today to open a short order because I am not sure if it is a horizontal substitution for a downward trend. If so, opening a short order can easily be washed out, causing back and forth losses and wear on the principal. Before the drop, if you were short on ETH, you should go long on strong coins. Of course, you should go short on weak ones. Now, looking at the position of chasing short, the support for 4 hours below is still around 1680. I will consider going short tonight.
