I will blame their poor knowledge here. In such a process temptation works. A person waits for a specified time or price to make a lump sum purchase despite having enough money. Many times they fail to buy. There is nothing wrong with waiting to buy a dip or a single buy, but it is not very efficient to grow your portfolio. There is a saying, "Slow but study, is a key of success". The DCA method fully conforms to this sentence. Not guaranteeing success in DCO but DCA method is most effective to grow your portfolio.
I see more about the level of consistency in buying from everyone who likes to buy Bitcoin every month because apart from being considered a clear investment step, it can also increase their portfolio more clearly and more real. Because people who take too long in terms of waiting for a certain price will also be very detrimental to them because time also needs to be used very well by everyone who still wants to buy and increase the amount of their portfolio more in the amount of time they want themselves. And from what you said it is also not wrong because those who like to wait for a certain price will not be bad enough, but they must also be aware that waiting too long to buy will also harm themselves.
