The halving was a major event that attracted many new investors to bitcoins, some started investing seriously some months to the halving just so to make some profit from it.The halving was what attracted them, but now that the halving has come and gone, do you think that the number of new investors will reduce for the now until the next halving is close again?
If they just entered to make the one-time reap then the numbers will go down but I don't think once they tasted the profits it will be too difficult to give away that and wait too long, the urge to buy before the next halving will make them to stay. And it also won't affect the long term users either, cause they know bitcoin is going to rise no matter what, only people who entered at $70K might be thinking about cashing out and never come back.
