You are very wrong here, using lump sum to accumulate a huge amount of Bitcoin at once is not a bad strategy and will not affect your financial status except you don't have the financial strength to use the amount you used in accumulating it, there are some set of people they see DCA strategy as stress to them because of there busy schedule so they just buy at once and hold and I see nothing wrong with that, for example someone decides to
use $2millon to $5million or even more to accumulate at once using the lump sum strategy and then hold it for 10 to 20 years, do you think he won't be successful in that his Bitcoin investment.
Some set of people in this thread only believe the best strategy for Bitcoin investment is DCA strategy forgetting that humans are different and that is how there financial strength, time and the rest is different what may go down well with you may not with someone else.
@sotelorene saying in his write up that buying Bitcoin at once may affect your financial status without proper explanation is missing leading, yes DCA strategy is good so also lump sum strategy, what matters is if such strategy will be comfortable for you.
Can you try to be more realistic with your examples?
Do you think that most normal people have $2 to 4 million sitting around to invest?
Try to share more realistic examples, and yeah sure there are some folks that have lump sum amounts available.. either they have the amount that comes to them suddenly, or they can draw the lump sum amounts from other locations (investments that they have).
I would suggest that even someone who might have investments into other things, they are frequently not going to want to cash out of their other investment and put that into bitcoin, even though surely there could be some cases in which they will make that kind of a choice.
Giving more realistic examples will be helpful, even though your overall point about lump sum investing into bitcoin surely is not a bad one, since DCA and lump sum might not even be very different from one another, since many times folks will DCA into bitcoin with as much extra money that they have available.. so they are not necessarily purposefully slowing down their investment into bitcoin, so if a person has a lump sum amount that either comes available or that they can make come available, it may be reasonable for them to buy bitcoin right way with that amount rather than delaying with DCA or even with buying on dip, even though surely someone who has a lump sum come available to them will tend to have more options than a person who is completely relying upon any extra cashflow that they might get from their regular income to buy bitcoin.
