It seems you are reasoning like me, I'm so curious these days in preparing for the 2024 drama. Nonetheless, my advice for you is to learn how to study your Bitcoin chart very well, all the answers you need are there. I recommend you use both weekly and monthly charts for effective studies.
Still, let me try to answer your questions:
No one yet knows the exact date of the 2024 halving or promises the same reaction, but judging by what happened in the last one, the pump started in April (a month before the halving). I guess it was due to FOMO, but was never significant like what started in October of the same year. There are months that ended bearish before the October pump that lasted till 2021.
This calls for wisdom, one should have started buying as early as April or even March and leave it for at least 9 months.
I would guess that April or may will be the month, there is no "exact" but that is as good as it gets. It means that we have about a year left, and you could start buying right now, since we do not need the exact date and hour when that will happen, we could start buying right now, that should not really be an issue.
I hope that people would realize before it's too late that they could invest into bitcoin without a worry, and they could make a profit next year after the halving as well, all they have to do is buy right now and hold until next year and maybe a bit more after that if they want more profit, but that's about it. I think it is important that people keep forgetting about how they could make a profit, and they keep questioning when they should get in, it's today, you should get in today.
