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.
The DCA method is not just for a declined market rather it can be use when the market is also high, investor who uses the DCA method doesn't wait for decline or..., Though accumulating when the market declined gives investors some advantage and for your information investors who enter during decline market are buy Dip and lump sum investors. To me I see waiting for the market decline before one can or will invest as a waste of time because it is possible that any opportunity one missed now can never be seen again.
