Waiting at the desk for this drop. 0.0208 is the line, $ROBO resistance above is very strong, rebound without volume and capital outflow. I didn't fight it head-on; when the signal appeared, I immediately followed the short position strategy and notified to enter.

Now the price has reached 0.01735, the short position has gained room, +798.77% on the books. My approach is to first take 70% profit, leave the remaining position lightly held, and see if there is further continuation; for those holding positions, set a stable stop-loss, don't hold through large fluctuations, don't chase missed positions blindly, wait for my new signals later. $BTC $ETH
