We should first focus if bitcoin would really can go beyond the $2000 mark value, because right even if we had seen that the price surge up to $1800 value it went down pretty fast to $1600, but it stop to the $1700 right now, the price is very unpredictable right now and I think we should focus on the reality basis of speculating the real price that bitcoin might pursue.
Yes and $4000 is simply not possible to achieve in this year as its very high and also an unrealistic value to think of in this quick time so our first target should be to touch the price of $2000 which seems to possible in the end of the year.
