Same thing was told for 2018 also but it happens to be opposite so i dont think that even till half year of 2019 wont see a spike in bitcoin price. It is like in 2016 -17, when the market was taking long time to break $1000 mark and most of them were just waiting to sell off their coins if it crosses. It took very long time to break and be steady and if i am not wrong most of them sold it when it crosses and went to $2000 to 3000. As most of them expected that their will be correction so they will buy back in low but as everyone knows it did not went down and gone very high up.
So i think this year it is not possible and in 2019 after same type of 2016 the market will test the patience of traders and then it will spike up.
