I like DCA as amongst the better of methods, if not the best method... except once you start to accumulate more and more BTC, then there may well be some value to engage in more buying on dip practices or lump sum investing practices rather than DCA practices.. s then the questions regarding how much BTC that we might have in compared to other assets that we have as compared to what is our annual salary all likely become relevant in terms of considering where we are at and what kinds of methods that we would like to employ in terms of whether we might still be highly in an accumulation phase or getting more into some kind of a maintenance stage, and further, if we realize that we are looking at 5-10 years down the road for wanting to start spending some of our value, then we might already figure that we are closer down the road as compared with someone who might either not be clear about how many BTC that s/he might need or maybe also whether they  might be considering even longer timelines of 20-30 years down the road... and sure it sounds funny to talk about bitcoin in terms of 15 , 20 or 30 years down the road, when bitcoin is barely just getting into turning 15 years old in January... but maybe even feeling younger than that if we might be considering the extent to which it may have ONLY had monetary value for a bit more than 13 years.
