I call $1200 after Segwit2X resolution November.  If there is a fork it goes even lower. 

• China will be selling until all the exchanges close, this will take a bit 
• China won't be buying, so obviously you lose a ton of buyers
• Prolonged uncertainty, HODL meme sheep will start capitulating
• Will take a bit for people to get money out their trezors, etc 
• Veteran buyers will be wary, new buyers will be scared off - Bitcoin headlines
• Downward pressure miners who need to sell and lack of buyers, whales selling

Maybe a shorter period bear market than last time (months) before a more healthy slow build up.
