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?
The thing is that it depends on the rate of people who has known Bitcoin as of now and had bought Bitcoin, that is two things, people may have heard of Bitcoin but yet to invest. Secondly, the more the year progress the more people who hasn't known about Bitcoin get to know of Bitcoin, Thereby increasing the rate of Investors who will want to invest. So back to your question, if we have lesser people get know Bitcoin, then the number of investors will reduce, but in other hands, it won't reduce rather increasese because people are given birth to everyday, whereas some set of people get to their maturity state and began to think about investment opportunities, and the most popular investment of our life time is Bitcoin.
