If a person has lump sum available, such as $1k to get started, and maybe he has an income in which he can buy $100 per week in bitcoin, then with the extra $1k, he does not need to invest through DCA, he could buy right away and/or he could buy at the dip (if the dip happens), so he has choices of the three different styles, and DCA is not always better if you already have a lump sum of cash come available to you. One of the reasons that so many people use DCA is because it is much easier to tailor some kind of a buying amount that goes along with their regular income coming in and their expenses, and so DCA also will allow an adjustment every week or whatever period that a person chooses to buy bitcoin under that kind of an approach/practice.
I like to think that DCA is the best method or strategy in almost every situation, even if a person has lump sum it just depends how disciplined and aggressive the person is with his DCA. If a person has $1K and he decides to DCA $200 for five weeks and another with the same amount just lump sums immediately, you’ll find out in the end that the one who DCAed was able to accumulate more than the lump sum even if it’s a bit.
I think lump sum is most beneficial in times of dip, I think that’s the only moment when lump sum is better.
Assuming the $1K didn’t come available at a time of dip, would it be better to wait ? How long would one have to wait losing valuable time and opportunities he could have accumulated more. And sometimes while waiting for a dip and price moves to an ATH even if there’s a correction after, there’s a possibility the dip might still be high compared to the time you had the sum available and decided to wait.
Look at the chart below ⬇️

Assuming he had the $1K at $100k price value and he was waiting for a dip and price shoots up, you see that the price never comes down again below $100k and now at whatever time he chooses to buy is now high compared to when he first had the money… that’s a huge missed opportunity.
