We have had a Halving in 2016. The next Reward-Drop ETA has been assumed to meet the 27 June of 2020. A doubling and halving event are related.
But before next halving there would be big chances for 10X growth because we can expect mass adoption in between times. Within 2017, we can expect bitcoin prices to get at least doubled. Simply my thoughts for bitcoins in 2017 would be price may reach $2000 levels. I am already getting prepared for that.
It is unlikely we are going to reach such levels in such a short time frame, don't get me wrong I will like bitcoin to reach those prices, but at the same time I need to get more bitcoin, so I would like for the price to not skyrocket like that.
