At times DCA feels like someone just trying to have some Bitcoin, to them it feels better to have some Bitcoin rather than none, but for me it is different, because every Bitcoin counts.
Either rich or poor you still need to apply some common sense when using DCA strategy, if you don't know about charts, like stochastic RSI, weekly candles and closes, etc you aren't getting the best benefit of DCA strategy.
If you keep using DCA strategy when there is some corrections in the movement of Bitcoin you will end up with more satoshi, and if you are rich and you can afford 1BTC on your every DCA days you can make an extra 1BTC easily if your entry is always on correction level. My point is it is still dumb to buy Bitcoin when it is skyrocketing, you are simply cutting some SATs off all in the name of you want Bitcoin now.
I do not think investing in Bitcoin should be done casually. Having a plan is important. Just buying Bitcoin without thinking can lead to mistakes. I think if anyone wants to invest wisely so he/she should understand market trends. Wealthy investors can benefit more from smart strategy. Keep in mind that investing in Bitcoin requires thought and understanding not just desire to own it.
I agree with you but want to add one more thing, an investor must know all the information about bitcoin before investing in bitcoin. Because I don't think there is any information that is out of this strategy or negative when investing in Bitcoin. You notice if one invests in Bitcoin following DCA strategy he will definitely succeed but it is through long term accumulation. Because if a person invests in bitcoins for a long time then his money will definitely accumulate and this money will turn into huge money after a long time. Using the DCA method is best for both new and old investors. Because investing in Bitcoin according to the DCA strategy, of course, it is universally correlated with each other and the investment results.
