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.
Many financial experts believe that Bitcoin will be over 20 thousand, and it will happen close to November-December 2018. I support their viewpoint.
