Yeah I believe it will at least reach to 50K point before next January. Because according to Fib Retracement it is more predictable that bitcoin will go 3X of last cycle's high which is 20K. And also their are many trading theories that assure the moving pattern of bitcoin to its next high. Best things is to wait and see what's gonna happen but don't get late to get in to the train before its too late.
I do not think bitcoin will achieve this price. The current market I see is pretty bleak. So in 2018 the highest price of bitcoin can be achieved is 15k.
With the way things are presently, it is indeed hard to predict. Last year was a bull year and we cannot expect every year to keep on that way forever. It is normal to always have huge fluctuations and that is what makes a market. However, in the future, we sure know this is likely but for this year, that is one long way to achieve and the possibility of that is close to none. At least the likelihood of $15k is still more realistic.
