I think its very posibble to happen, now that its only 1st month of the year and too early to become hopeless. I bet before the year 2018 overs, The price of bitcoin will smoothly reach the $20K before the year ends.
Indeed, be optimistic bitcoin will touch 20,000$ again or even more before this year 2018 end. Bitcoin was so fluctuative hence, it is not possible for it to happen. Yet, day by day cryptocommunity is become larger and this means that the demand will rise same on its value. Always remember that don't panic and be wise on our decision because it might lead to our loss plus, have a trust on it.
The year 2018 is still very long and the chances of a much higher rise are still very open. I also have a high sense of optimism to believe that the Bitcoin price increase could exceed the 20,000USD rate. Increasing trust in Bitcoin and also increasingly using Bitcoin in all financial transactions that we do then it can make Bitcoin prices increasing. This can not be denied because the increasing demand will give positive value to the development of Bitcoin.
