Sounds like you understand the idea, so it is a matter of putting theory to practice and trying to have fun with it, even though it can take a long time to play out, it can be fun too.

Think of the guy who invested $7.9k between 2018 and 2020 (investing $50 per week), he might have had felt kind of bad during 2018 and even into 2019 and even during parts of early 2020 he felt pretty bad during the March 2020 crash..

So by the end of 2020 he had accumulated a whole BTC, and he started to feel really great during 2021, but maybe not so great during 2022, but during 2023 and into early 2024 he is feeling pretty damned good again, and even if he continued to invest at the same $50 per week rate during the whole time and maybe in the second 3 years he only accumulated 1/3 of a bitcoin but he is currently at 1.34175 BTC with nearly $16k invested, so he is feeling pretty good about all of it, and sure maybe he was not consistently $50 per week, so if his specific performance had varied from what he could have had gotten in employing a DCA strategy, then maybe he needs to reconsider if he should change his strategy - however at the same time, if he feels that he is on a good path, he might just keep with $50 per week or maybe he might feel that he is doing well enough in his investment he might want to increase his weekly amount to $100 per week or some higher amount, even though he probably would have had been better to increase earlier on, but sometimes people will kind of just get caught in a pattern and even some people use automatic weekly buys rather than doing them manually, and either way has its advantages and disadvantages, my personal preference is manually in order to engage with and to monitor my investment more, but some people don't want to (or can't) have that much involvement with their investments..
