You are absolutely correct and most times what makes some investors to be overly aggressive is because of the market Dip some people use this period to ruin there investment unknowingly because the moment you accumulate or buy more than you are suppose to buy in this period you will definitely see the consequences within a short period of time. Ordinarily Dip is suppose to be an opportunity to increase or double one's portfolio but i don't know why some investors abuse it and sometimes it is been done out of greed or ignorant of the fact of what the outcome will look like.
In addition, buying too aggressively can cause sudden losses, for example if you buy when the price may have dropped and you think it has entered the support point but it turns out there is still a further decline if you buy it too aggressively at the beginning then in the next decline we do not have enough funds to buy more at the lower price so it would be better to buy periodically such as using DCA it will make us more controlled in making long-term investments and we can see the benefits in the existing DCA calculator if the target we have achieved is met.
It would not be right to call it a loss because you might have refrained yourself from buying Bitcoin for trading purposes. If the price of Bitcoin decreases soon, you should have patience because you are not a traders. That is why the Bitcoin market is called volatile but DCA method stabilizes Bitcoin accumulation for investors which is within their means and expectations every week. If you have floating cash funds it would be a best decision to buy aggressively even if the price decreases. Bitcoin can recover its value repeatedly.
Short-term traders are afraid of losing money by buying Bitcoin. Long-term investors do not have the fear of investment due to running Bitcoin accumulation. I myself am a good example of this. I am a very small Bitcoin accumulator regardless of the price I continue to deposit Bitcoin regularly. Long-term Bitcoin investors save safely every week/month from their discretionary income in DCA method.
