In 2016 Bitcoin price had a rally BEFORE the halving and reached $779 20 days before halving, then there was correction and local low was $465 one month after the halving. And then 5 months of uptrend with a top at $1140.
If we try to project that to this year's situation, I'm predicting 12k to 14k on halving day (May 13), after that a correction to 10k and then long lasting uptrend with 21k to 24k till end of the year 2020.
