I think if they are still in the early stages of accumulation I think they are better off focusing on buying more routinely, collecting satoshi by satoshi to reach their target.
But what you said might be better if they have reached the 80% accumulation stage of their planning so that investors can wait for a decline even though it is not a good decision compared to the best way to continue buying DCA.
Corrections always happen because the market continues to move every day even if they continue to buy with DCA they also get the opportunity to buy at a cheap price.
On the other hand, to strengthen their portfolio, one thing that is better to apply is to continue to accumulate bitcoin every week.
Do you know, out of the many investors, they could make mistakes because of carelessness in making decisions, be it budget adjustments or their mental unpreparedness. So in this case I am more convinced that an investor must prioritize discipline in carrying out the investments they make.
Everyone who already has a plan and also has the intention to realize their plan will definitely do the things they need first before heading to the end goal of their own plan. Because people who know how to run a plan will never be afraid and hesitate to keep moving, whether it is moving to buy Bitcoin or moving to get more money to be able to buy Bitcoin again even though at this time the price of Bitcoin has returned to more than $87K. But that will never be a big problem for people who like to invest because as long as the goal is still worth running, then they will never stop buying Bitcoin. And your suggestion is also a good suggestion because DCA is still worthy of being relied on by many people who still want to accumulate by buying Bitcoin gradually at different times.
