Investors doesn't need to "exceed their regular amount for buying Bitcoin in their DCA strategy before they could be seen as investors who are buying aggressively. If you are consistent and persistent in accumulating Bitcoin and even if you don't exceed your regular amount for buying Bitcoin in your DCA strategy, you are accumulating Bitcoin aggressively because you are always active in accumulating Bitcoin, and you can never be compared to investors who aren't consistent and persistent in accumulating Bitcoin. The concept of aggressive buy in Bitcoin investment is all about accumulating Bitcoin consistently and persistent, so if you are accumulating Bitcoin with $5 every week, you are aggressively investing in Bitcoin because that is your own level of aggressively. It's when you increase your regular $5 for buying Bitcoin to $10; that's when you are being over aggressive, and it will take you out of the game if you don't stop it early.
Maybe what you said is true. But I think the level of aggressiveness of someone investing in bitcoin cannot be equated with buying with the DCA method. Because the DCA method is periodic purchases, which means not buying large amounts at one time. While the aggressive purchase of bitcoin is buying bitcoin with a large enough nominal at one time or at an unspecified time.
Your points are not disputed, but think about it this way, someone who accumulates Bitcoin consistently using the DCA strategy, buying at least up to 5-10% of his income from his discretionary funds, and someone who waits only for dips and buys aggressively from his income using up to 50%, who buys aggressively and who would acquire more Bitcoin in the long run?
Secondly, you know that what Mr A might call aggressive buying can be what Mr B would use as little fraction for accumulating Bitcoin using the DCA. It all depends on the income supply and discretionary income made available by the investor as income differs. So my investment using DCA through discretionary might be someone elses Aggressive buying. So we can't not really say that the level of aggressiveness of someone investing in Bitcoin cannot be equated with buying with the DCA just as you stated above. A consistent DCA Bitcoin accumulator can in a LONG RUN outbuy an investor that only operates in the Dip.
