I have details that might be used as a comparison for those who want to analyze well;
Halving 1
November 28, 2012
Highest price 2013, November $ 1,127
Halving 2
9 July 2016
2017 high, December $ 19,665
Halving 3
12 May 2020
Highest price (estimated 2021)
now is it true that the third halving will be able to change bitcoin or even decrease, but usually after the halving there will definitely be a change.
