Right after the first halving in 2012, the Bitcoin price rose from $12 to $140. Weeks after the second halving in 2016, Bitcoin started a rally that propelled its price from $582 to $20,000.
the problem is :
in 2012 and 2016 halving, people still put a lot of doubts in bitcoin saying bitcoin will have zero value, majority did not believe that bitcoin will be worthy in the future and then the price skyrocketed, proven they all wrong.
nowadays majority so over confident about the upcoming bitcoin halving making speculation it will worth 5 to 20times from the current price , guess what should happen? the price fall down , prove the majority wrong?
a little bit confusing , i just don't want to act over confidently , it was never safe for your health

The price has no mind of its own and it doesn't want to do anything or prove anyone wrong. People see the halving as a catalyst for growth because of math.
If the reward gets halved the value of new coins will have to double.
Even if the price of the existing coins will not miners won't sell new coins for 8k USD but will want to make some money mining them and wait until the price is at least 16k. This will create a shortage of supply and those who decide to buy will have to buy from holders not from miners.
