You can still buy dips without necessarily waiting, I believe DCA and dip buying can co-exist without stopping your regular buys. You can always share your DCA amount into 5 parts and maintain your consistency with 4 parts and continue saving the 1 party consistently until your desired dip surfaces and you lump sum on the dip with already accumulated funds for it and if the desired dip doesn't come by, you buy up with the saved funds or use it to increase your aggressiveness for a while.
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.
