This is the first bearish structure breakdown since the beginning of the bull run. Meanwhile majority is still waiting for 10K. I am not saying you should sell, but would be cautious about buying the dip here, a broader correction can happen now. I still believe that we have to visit at least 6-5K price levels. It is dangerous to short here too though. It can be just a bear trap as well, I think that staying aside is the best option for now.
