This your illustration is entirely not a bad idea, but I think that if you have a reserve funds in place while buying regularly with your dca accumulating strategy, you can easily buy a huge chunk of Bitcoin during the dip with your reserve funds if you have it in place.
The only problem and where i tend to have problem with most Bitcoin investors is that they wait for it and stop their accumulation entirely, which i think will limit them in accumulating or reaching their Bitcoin over accumulation status early.
Some investors really have a misunderstanding concerning that which is why you'll see them wait for the dip to acquire a large chunck of Bitcoin, they don't understand that while doing the DCA you can still acquire a large portion of Bitcoin so far you have the required funds for it intact, you mustn't really wait for Bitcoin to go dipper cause that's a waste of opportunities. The good thing about the DCA is that you can still use that particular strategy and still buy Bitcoin in large portion while on it and a massive dip occurs, Bitcoin investment is not something that's very tough to comprehend.
