But because I believe you don’t have enough capital, always wait for a DIP, try to use your capital as efficient as possible.
You are missing the point of DCA. The entire point of DCA is to not try to time to market; pick an amount and a time frame, and invest regardless of what the price is doing at the time. As soon as you try to time the market then you are no longer DCAing. If you want to do that, that's fine, but if you want to do DCA then you should see if you can set up automatic recurring buys so you don't even have to look at the market at the time of your purchases.
I understand. I was merely telling him that DCA might not be for everyone. Capital is limited, plebs can’t simply buy anytime, and not care, especially with an asset as volatile as Bitcoin.
