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.
Especially in Bitcoin investing, it is more important to have the right amount of cash flow to be aggressive regardless of the price. You should keep yourself motivated to save equally during dips or bullish times. Waiting for a market downturn will reduce the amount of floating cash and this may not be desirable for any investor. Being aggressive during a downturn is good if you are able to truly understand that it is indeed a recession. It may be that the price will go down further. Some investors actually make the mistake of waiting for the price to dip for a lump sum buy instead of continuing to save and regret it when the price drops further. Regular Bitcoin accumulation having a proper management of floating/emergency funds is where an investor wants to develop his mindset without any outside intervention.
