I believe that the price per bitcoin is going to be more than that as in the last year the price was $19k ath but if the bitcoin will reach mere &$20k at this year's end then it will contradict the growth of bitcoin which it has been showing from the past years where it grew more than 4 to 5 times each year. So form what I believe the price per bitcoin will be more than $40k by the end of 2018 and for the same i have been preparing from this market fall.
