Just remember that folks.
The Bitcoin market was bullish before the two previous halvings (hence no clear correlation in my humble opinion). But if you believe there is a correlation then it's important to consider other indicators, and not the halving alone.
How much my memory serves me, and according to the official data from CMC price of 1 BTC on January 1, 2016 was around $400, and it stay like that next 5 months until halving. I wouldn't call it bullish, and therefore OP assumption looks like another worthless speculation.
Price growth is realistic to expect after halving, especially in the last quarter of this year, but the new ATH not before 2021.
