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.
Given the daily volatility of bitcoin I argue that daily is likely to be more beneficial.
I would agree. Daily buying will get you closer to the overall average price of bitcoin than weekly buying will. If you assume bitcoin is going to continue on a overall upward trend, then over enough time daily will work out more profitable all other things being equal. However, as I mentioned in my first reply, the fees will not necessarily be equal and could result in significant differences.
