You mean the halving.
If I were you I would stop expecting way too much just like before.
2017 is not the year of the halving it was July 2016 when it happened. So you cannot really connect the halving into when the bitcoin price will pump.
Just buy bitcoin. That is all you have to think about for now.
The cheaper the better. But when will you know when it is cheap? You decide.
Many thought Bitcoin will go to $5000 but $6800 proved to be lowest before current pumping start. There is no low or nobody can say whats the lowest before bitcoin starts an upward moment. Best is to start buying bitcoin at dips and HODL while bitcoin goes up.
