I like the idea of either lump summing and/or front loading DCA in the beginning in order to attempt to get a higher stake into BTC right from the start, and then thereafter have money for DCA and buying on dips, and sure, maybe you don't really need to buy on dips as long as you are mostly DCAing.
Otherwise, surely there can be some differences in finances, and some beginners will neither have funds available to lump sum and their finances might be in worse shape in the very beginning so they are not able to front load (meaning doing BIGGER) DCAs in the beginning... so surely each person should be attempting to take the approach to BTC that best works for them, and it may also be the case that they should look at charts in order to help to inform them how aggressive that they might be, but it is not necessarily going to tell you a lot which way the BTC price might go, even if you do look at some charts and try to figure out where we are at, where we had been and what does that mean in terms of where we might be going. Beginners might have more difficulties with these kinds of matters, even though even longer term bitcoiners are not good at it, and even though I have been staring at bitcoin charts for nearly 10 years, I still don't like to make proclamations that are much beyond 50/50 in terms of where we might be going in the short term.
In this stage, initial purchases and subsequent stages can be adjusted to their level of financial strength. In general, beginners don't quite understand how to analyze charts and of course I felt that way when I first got to know Bitcoin. However, every initial purchase will always be a beautiful moment for them in the future and many of them invest larger amounts at the initial purchase stage. However, for me, if they don't act aggressively in the initial purchase and balance it with the appropriate amount at each stage, it would certainly be better, but it all depends on how they invest.
Sometimes they can include larger amounts of money in their investment planning either at the beginning or at the end or when prices fall. But chasing the price down is certainly not a good option because if the price continues to rise then those who are waiting are a little frustrated with this, which could result in them making an instant purchase. But if they do it with DCA of course they can buy at any price without waiting time to find a cheaper price.
