As far as I know, according to history, Bitcoin's halving did not directly increase its price at that time, but roughly a year later. You can check from here
https://cryptoslate.com/comparing-bitcoin-halving-cycles-whens-the-price-top-due-this-time-around/, for example. You can see this. Here is a summary of the approximate timeframes when Bitcoin reached its all-time high (ATH) price after each halving:
- First halving: November 28, 2012
Bitcoin reached its ATH on November 29, 2013, which was approximately 367 days after the halving.
- Second halving: July 9, 2016
Bitcoin reached its ATH on December 17, 2017, which was approximately 527 days after the halving.
- Third halving: May 11, 2020
Bitcoin reached its ATH on November 10, 2021, which was approximately 609 days after the halving.
Uhm, before the bull run, I think there will be a major crash first as a chance for whales to accumulate their bags.
