Oh okay, im not exactly follow the theory on the book or in wikipedia

Im DCA=ing the dip, because just like the meme you never know where the bottom of the dip.
Offcourse you feel free to DCA as in wikipedia or theory on the book, if you feel that you should do that

You are free to do whatever you want with you money, really

The point was not that you should do DCA. It's up to you.
The point was to not call DCA something that's not DCA, since what you do now is confusing anybody reading and trying to understand
