I've read some other comments in the thread and what your saying seems quite contradictory, I don't think the dip is the only time we should accumulate bitcoin since we are using the DCA method that involves buying at intervals and helps reduce the impact of market volatility on our portfolio, besides those who buy only at dips would miss out on all other times to buy.
yeah you're right, when using DCA one should not be bothered with checking Market always when accumulating, because that is all system of using DCA we can't predict market movement to know the best time to buy , instead we use DCA to buy at any price interval either we buying when there's decrease or increase in price. But one is tend to be more aggressive (with his DCAing) when there's a dip in price after using he or her reserved funds to purchase the dip . To have more chances to have alot of quantities of Bitcoin stashed in their portfolio, depending on the individual financial capability. But this doesn't mean that one should always have the mindset of waiting for the dip before accumulating, so one can still be aggressive at any price depending on his plans and financial capability expecially those with the mindset of holding their Bitcoin for long-term investment.
This is actually what most investors have failed to understand, that most times the dip they might be waiting for may not come and it will make them to lose so many buying opportunities in the market, while with the DCA method, you can be buying Bitcoin bit by bit regardless of the price, and you can even buy the deeper most part of the deep if you decide to seize the opportunity by buying aggressively during that period, as long as it doesn't affect your emergency fund, and at the end of the day, you will definitely have more Bitcoin in your possession and you will be more profitable as long as you are a long term holder
that is the disadvantages of always waiting for the dip always reduce your chances of accumulating more quantity of bitcoin, most time those that are not financially stable, compare themselves to those who are financially stable ( those are wealthier) in accumulating bitcoin. Those that are financially stable can easily purchase large quantities of bitcoin with lump-summing whenever they have the opportunity to purchase the dip . While those who are not financially stable may not be able to purchase such quantities at once , but instead use DCAing consistently and the other methods of accumulating to accumulate more bitcoin. Without them using or having the mindset to tamper with their emergency funds.
