This coming Q1 of 2019 Bitcoin will hit 5k or even 6k. Let's be positive on this kind of market. The year of capitulation is almost done. But then price will change when mass adoption happen. So I guess in the 2nd week of January bitcoin will pump.
Any information why you said that we will hit at least $5k? As far as I'm concern we are still in the bear market so its going to be difficult to see a reversal to $5k-$6k.
Anyways, all we can do is be optimistic that 2018 will be much different and let this bear market end and see a new cycle comes in. I don't like though the massive spike again, would rather see the price trading sideways or gaining slowly as months passes by.
