One major thing i took note of about your statement is that everything in life has it's benefits and disadvantages, although the DCA is the best strategy for managing risks in Bitcoin investment but it still has it's own down side which is that someone that's not commited to tasks would find it difficult to invest with it since it's something that should be done consistently according to the period the investor can regenerate their discretionary be it weekly or monthly but in general the DCA is more positive than negative when it comes to Bitcoin investment, one thing i love about the DCA is that it helps an investor to invest consistently regardless of market volatility.
You made some solid good point here. Like I used to say, there isn't any strategy that is bad to invest in Bitcoin. Both buying on dips, DCA and lump sum are all good strategies, but the choice of strategy must align with your investment goals. If it doesn't align with your goals that is where it becomes a wrong strategy that you use.
There are many people that invested using DCA and they are successful, while others used lump sum and occasionally buying on dips yet they are successful. On a normal day the strategy doesn't really matter but how you utilizes these strategies to your own advantage is what truly matter.
