I think for now or at the end of 2018 the price of bitcoin will continue to last around $ 3000 until the beginning of the month of 2019 ... and will rise again in the second or third month of 2019 ... I am very sure Bitcoin will continue to experience significant developments until reach $ 10,000 ... and most importantly, don't panic to sell it now
What strategy that you used? You give the clear numbers to predict bitcoin price in the future. Someone has a difficult to predict it, even they got confused to convince that his predict will come true. But, it never happen for some poeple they just fall to loss again and just can leave it and come back when the price up until the price he bought.
