Maybe you misunderstood it because you only focus on one point. I have given an understanding in that post that DCA is the best so in that case we invest with the DCA pattern and also in conjunction with buying on dips.
Isn't buying on dips the right choice to follow up our accumulation along with routine accumulation every week. You must be able to organize all forms of plans if you are really focused on taking advantage of opportunities when prices fall
Yes, buying and holding will make you comfortable in any situation because your steps are for the long term so holding is an option that must be required.
Investors use the DCA technique in a declining market situation and this is a very common technique used by every investor, they certainly save in a declining situation and continue to buy and choose to survive and wait for the right time and their strong predictions of the success they will get later.
