In my own opinion, bitcoin will not crash and will hit 20K USD by January 2018. Because of the fork bitcoin is dumping but fork will not last until 2018. After the fork I expect that bitcoin will pump again and will continue pumping until January 2018 so it can hit 20K USD easily. Bitcoin price is very unpredictable on the past weeks. No one expected the price bitcoin has reached. Because of that it make me think and believe more that bitcoin can hit 20K USD by the beginning of 2018. What a nice year if it really happen.
