If I understand it correctly I think the most important part of the process is simply the fact that it's putting some share of your current income into an actual growth investment. DCA in that sense is less about getting a better return on your overall investment, and more about starting to build those long-term investments in a way that has a predictable and minimal impact on your day-to-day household budget. It's not answering the question of "what should invest in" but rather "how do I start investing?". In that sense I guess we should probably be more clear that you can DCA into actual solid long-term investments rather than throwing your money at crypto. Hell it would probably be less destructive on net to take your monthly DCA to the literal casino and put it all on black.
That actually raises an interesting point. I would be curious to see if DCA is actually doing some harm mitigation by giving the truly pilled victims a maximum that they're going to throw to the grifters, compared to how often people set it as a minimum amount of money. If they weren't DCAing would they be investing less by waiting to see what was left at the end of the budget or more by not bothering to seriously plan their expenses at all?
Have any actual courts ruled in favor of this nonsense? Because I thought fair use was tied to things like public benefit and transformation more than a direct number of copies. Like, I'm pretty sure that I'm not allowed to fax a book to myself even if I put the original through a shredder, and that's ignoring the question of how much gets inexorably lost in the process.
