This is really a good way to learn, thanks to the team behind this, but truthfully this is my first halving that I will be aware of.
When I heard of bitcoin halvening, I heard a lot of people saying the price will increase we should buy and hodl. Even then my thought was that the price will become doubled when the halvenng is done. My own expectation was getting around $15000 or more because the hype was much. Later when I got to read about it from Forbes, that was when I realized the hype was not all true.
The only thing that I just got to know is that after halving, the rate at which bitcoin is mined will reduce and as such law of demand that says

the lower the the supply the higher the demand and the higher the demand the higher the price.
