Using the DCA approach is still okay because it helps to avoid the overthinking of not buying at a lower price than the current market price when there has been a price reduction at some point. Because of the volatility of the market and the price action that comes with it,
DCA is a safer approach so that you'll have points when you should buy and what will be the amount that you should purchase for those points.
the DCA approach is still the best way to accumulate bitcoin. When there is a drop, you can also use it to accumulate more bitcoin than before. The dip is not certain and cannot be predicted, but you can always accumulate gradually using the DCA approach.
Those that don't have an option but only to DCA can do a lot better unlike those that don't buy at all. But if you're blessed and you'll be able to buy with an entire amount on the spot, honestly I think that's better.
