Buying the dip has been a golden opportunity of buying more of a coin with the same amount that would have given a lesser amount of coin from it's previous high although, it shouldn't be seen as a primary strategy for accumulating Bitcoin but it should be a secondary strategy without over doing it.
I agree because it’s not always that the market dips but this is just a good opportunity to accumulate more when this chance is met. But if you already want to invest even in time where it’s not necessarily a dip then I still would urge you to do so.
Especially if you have already missed the dip but do not want to miss on the raging bull run then I suggest to accumulate in other way.
