Honestly, those sets of people that always want to buy the dip, I view them as short-term holders, which I see as traders. They always have the intention of selling in a short period of time. But for anyone that is ready to hold their Bitcoin for a very long period of time, I don't think they should have that type of mindset. This type of mindset can hold someone back from investing in Bitcoin. It has happened to many people, all just because they wanted to buy Bitcoin at a cheaper rate. They are still waiting for the Bitcoin price to drop to $20k. They saw it and refused to buy at that time because of the mindset of always waiting for a dip. In fact, many have even wasted the money in other ways.
Technically you are not right at this because there are investors which may have gotten to their maintenance level in their bitcoin accumulation journey that can also decide to be only be practicing buying the dip because they don't need mush of buying frequently anymore using the DCA, but can as well make use of reserve funds and buy the dip only. However, those that still have a long way to go in their accumulation journey do not need to time the market but rather focus on maximize every opportunities to fill their bags and if possibly being aggressive without overly doing it after considering how much of their disposal income/discretional, they should take advantage of every buying opportunities especially if the money for invest is readily available.
