We shouldn't only accumulate Bitcoin when it is dip for it is important we accumulate all season though the dip is just an opportunity for an investor to accumulate enough Bitcoin and HODL but if the goal is only to accumulate when it is dip it will really delay our Bitcoin investment journey. So I think the goal should be keeping on accumulating more Bitcoin and HODL weather the price of Bitcoin is dip or not the importance thing there is how much Bitcoin you were able to accumulate and how long you were able to hodl.
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.
I don't think we have to argue about which method is the best because what might be the best for you may not be suitable for the other base on their personality or schedule. Therefore, the existence of various methods of bitcoin accumulation is to create some varieties to so that individuals can chose which is best for them. Inasmuch as we know that the DCA method is a great method, there are people that cannot just use that method for example, people who are involved in regular traveling due to their work or business schedule, instead of using the DCA method, they will go with lump sum buy. This does not mean they are doing it correctly, it simply means they are constrained by their work or business.
Provided the intention is to invest and HODL, then whichever method that is adopted is fine. However, for people who have the time and patience to wait their DCA schedule and for the dip to occur, a combination of both methods can be a great arsenal at their disposal.
