In the end, it seems that amongst the most reasonable and prudent of planners, would not overly lump sum at the top, yet if they were to make such an error, then (absent some rare surprise/emergency exceptions) they should be more than ready, willing and/or able to continue buying BTC if the BTC price drops after the lump sum investment and especially if such dip lasts a long time and/or dips in considerably large kinds of ways. Personally, I don't give much of a pass or have a lot of sympathy for the lump summers who are not ready, willing and able to follow up with further BTC buys.. and if they have blown their whole wadd, then they are likely guilty of gambling rather than investing, which sure they are free to do what they like, but I am also free to not have much sympathy for such an approach to BTC.
In such scenario the best and the right thing to do is to keep buying, even when the price continues to go down , aslong is bitcoin even though it may takes years for it to recover one thing for sure base one his past performance it will surely come back stronger. When one continues to buy is not only increasing his stashes of bitcoin in a nice rate but at same time minimising losses because at that time you will be using DCAing to be purchasing bitcoin at different price interval. And not only that it will also increase the chances of making a bigger and better profit in a long run . And for those with goals as the price continue to drop it will also increase the chances of you getting to your target goal or accumulating goal faster .
Stacking Bitcoin is of course better using the DCA pattern every week. It is true, as JJG said, that some examples of investors are definitely trapped at peak prices because they buy all at once without following up to continue accumulating every week. Yes, it will delay their investment because they do it all at once. To solve this, it would be a good idea to divide the money we have into several parts in DCA accumulation so that we don't get stuck at one price in the investment we make.
Some of them often assume that their entry is the lowest point, but actually they are wrong because the market can change suddenly, so DCA is the best for finding the lowest price in Bitcoin accumulation. With regular purchases we will also be more active in studying Bitcoin and we will also be more active in managing cash flow for our execution every week.
Even though in the pattern we are in the same destination, if DCA is compared with Lumpsum then I prefer DCA because it is easier for us to find the lowest price point in the long-term investment journey.
As Saylor did, he bought at the peak of the price cycle, and bought again when the price fell and he routinely did this so that the average execution price was below the current price. So there is no analysis that he needs but his habit of continuing to buy makes him find the lowest price in long-term investments.
