I believe that we are in a bearish trend and it will probably last till level 50% of the wave from 2015-12 to 2020-08 which is near the support line of the main pitchfork (the black one, something around 1560$) and after that, I would expect we'll enter a bullish trend to meet the median line of the main pitchfork. There is a possibility that the decline continues to touch the trigger line of the main pitchfork and also the median line of the second pitchfork (The red one, something around 1347) which I believe the probability of that is not considerable.
