It is impossible for bitcoin to go below 6000USD and then you talk about 2000USD. Bitcoin is a well developed currency and we cant match any other currency with this because it is far better from all of them. The demand of bitcoin is rising day by day so I think this will greatly increase its price rather than decreasing it. I think the future of bitcoin is bright and its price will increase in future, not to be decreases.
Bitcoin goes to $7000 and comes back to $6000. Bitcoin $1800 by end of 2018 looks coming....
