I understand what you are saying but I think dips that are pursued on top of your discretionary income can be perilous. Bitcoin can fall and at times fall further and therefore, when you overreach it may probably panic and sell it when you really need the money. The entire power of DCA lies in that it creates consistency and eliminates emotions.
Missing a single dip won't make much difference in the greater scheme of things but losing discipline will be self-destructive in the long run. The consistent ones in the past cycles would always turn out to be profitable even without timing the dips perfectly. Better to strike a balance such that you can still have money left to invest when even greater opportunities present themselves.
It can be more effective when you have a strong backup fund and sufficient cash flow. There is nothing wrong with buying in a falling market, but waiting for a falling market or planning around a falling market can prove you wrong and if you fail to catch it, you can take the wrong steps which can cause you a lot of losses. A market fall is a good opportunity for every investor to stock up. Let it happen naturally, when you try to buy the dip artificially, you can be forced to take the wrong steps. Because you do not know when the dip will happen and how long it will last. Here you are more likely to panic and there is a higher chance of hurting yourself.
If you do not want to go through such a harmful possibility, try to be consistent in the market and continue to buy regularly (DCA). If you have a good knowledge of investment management and risk management and you have taken the steps, then you will get the opportunity to buy the dip naturally and there will be no much chance of loss. Another thing is, do not be unstable in any market situation, but rather be calm and take the right steps.
