You actually sound confused and at the same time missing up ideas and it shows that you don't really know what you are saying, one can still be aggressively and consistently investing with the DCA within their own level of finance and discretionary income without over doing things, meaning that the DCA allows investors to buy regardless of the market conditions whether in high or low, from what you are kinda saying suggesting that people should not buy when the price is high which is wrong, you can buy any time provided that you have your investment money readily available, an investor doesn't look or consider the fraction they are buying before buying what is most important thing is that they are buying and within their own level of discretionary income, and given priority to buying Bitcoin aggressively when the market is in dip can result many in to being carried away and using money not meant for investment to invest.
It is good to be aggressive in a market downturn but there is no reason to be aggressive when you see a decline. If we have regular cash flow we can increase and decrease expenses and buy aggressively. It is good to be as aggressive as possible but that does not mean that we are overworking and doing things that we cannot afford. Anyone who tries to be aggressive will buy regularly and consistently and will not use his aggressiveness until he has established both cash flow management and all emergency funds and reserve funds.
I really don't see too much aggressive buying as a problem here, as long as you are doing it from your decretionary income, then their is no cause for alarm, where over aggressiveness is a major problem and a serious concern is if you haven't properly taken care of yourself and your basic needs, that's where the problem lies, because in such a scenario you might later tempered with your Bitcoin holdings just to address some financial needs that was not properly taken care of due to the fact that you got carried away by buying aggressively.
So what am trying to say is that if you want to accumulate Bitcoin aggressively during the dip, it's not a bad idea, but make sure that it's being done from your discretional income, because that way, you wouldn't have to fall back to your investment because every other things has been properly taken care of.
