I see this as something that will make an investor not accumulate his Bitcoin comfortably because the investor will be saving the fund that He/she is supposed to use and settle his financial challenges and use it to buy the Bitcoin dip. Instead, an investor can reduce the amount of money he/she wants to use in accumulating Bitcoin through the DCA strategy and save the remainder to use and buy the Bitcoin dip. For instance, if Johnson is supposed to invest $50 every week in Bitcoin, he can invest $40 and save the remaining $10 to use and buy the Bitcoin dip.
The examples and suggestions that you say do look good and make sense, but on the other hand I don't think that Bitcoin investors are so stupid in using their money for several things. Including buying for long-term investment or buying to achieve short-term profits and the like, because from several well-known investors who have invested in Bitcoin very often, we can also take the example that they also often use their money very wisely in any case. So those who sometimes forget to make their Bitcoin accumulation comfortable are novice investors who are so excited to invest in Bitcoin that there are one or two things they accidentally forget.
