In my own case, I would consider DCA with discretionary funds as the most secure long-term course of action, whereas I would consider dips as an opportunity to be a little more aggressive provided that your financial capabilities permit it. In that manner you would develop progressively without putting aside money that you could require the next day.
Don't rely on the market to be aggressive in investing. Rather, you can be aggressive in investing as soon as you have prudent money depending on your ability. Whether or not to be aggressive in investing depends entirely on you and your financial situation. Being aggressive in investing is not wrong or obligatory. Being aggressive within your ability will take you a little further in your investment journey and will keep you moving towards your goals faster. Be careful that being aggressive does not put you at any financial risk and does not hinder your continuity.
I think both of your opinions are excellent. Being aggressive in buying BTC when the price drops is certainly a good thing if we have idle funds. And of course, buying using the DCA technique and buying BTC without DCA are certainly good steps. So, doing both is certainly better than not doing it at all.
However, your opinion is also correct. It would be better if we didn't consider the price when BTC dropped or not when buying BTC. Of course, accumulating BTC using the DCA technique doesn't consider the price, and that will certainly make someone who accumulates BTC feel comfortable. But of course, when investing in BTC, the most important thing is to use idle funds. Anyway, keep up the good work, to those who use DCA and others.
