waiting can actually be a strategy too and never a bad thing. For instance, someone using a combine DCA with buying the dip can continue buying through the DCA with the amount budgeted for that while setting aside the amount for buying the dip and wait for the dip to actually happen, knowing that it will surely happen because price does not continue in one direction forever.
Of course each and everyone has the strategy that works for them so actually I agree with you that waiting could also be regarded as a strategy because there are people or rather investors who uses different methods of accumulation such as DCA and also waiting for the price to dip so that they will take advantage of the opportunity, though for those that has a good source of income the strategy Will be very useful for them in other to enhance there accumulating process, one good thing about the strategy is that your accumulation will not be dependent to only buying at dip but instead you already have a budget that allows you to be doing your normal DCA while you wait for the decline in price of Bitcoin to buy.
