DCA is probably better than buy the dip because DCA is more basic in terms of NOT having to attempt to figure out if there is a dip or not.
Sure buy the dip can supplement DCA, but I don't like it as much as a primary BTC accumulating strategy, and sure the more aggressive that a person is with the DCA, then maybe the less funds that would be available for buying the dip, but there should be practical ways to attempt to accomplish both.
Overall, I agree. If you factor the current point in the apparent cycle, however, I think putting stronger emphasis on buying the dip (definitely for the last few months, probably continuing for the next few months?) in addition to your methodical DCA schedule will be more rewarding. If I was accumulating now, I think I'd keep the pressure on BTFD under 100k.
