The 150 days interval used by the OP does not allow the effect of the halving in 2012, 2016 and 2020 to be seen, he could have added the peak attained after the halving of each year for the effect to be well appreciated. Nonetheless, halving is a good tradition of Bitcoin and perhaps a time for BTC lovers to make money, but many are overrating this.
I've read some people claiming that 2024 halving would make BTC reach $100-150K, while some even go as high as $240K due to a cycle theory that might not see the light of the day.
As for me, the 2024 halving will surely help BTC to fly higher, but I predict that nothing higher than $100K would be witnessed. Precisely, BTC should not go above $87K due to the halving.
There is really no exact date, nobody could find that exact date because there is none. The reality is that, one thing is a big fact that we can't deny at all, and that fact is "after a certain time passed over halving, the price starts to go up", we do not know how long needs to pass, or how high it will get, none of them is known.
What we know is that it is going to be some time after the halving, and we know that it is going to be something that will be higher than what it entered the halving as. This is why it is a smart decision to buy a bit before halving, and sell a while later, that way you could profit, better would be buying now and selling after 3-4 halvings later.
