To build a good Bitcoin portfolio, in addition to buying regularly, it may be a good idea to buy a little more aggressively when the market is in dip.
While this sounds good it also comes with or requires certain level of preparation reasonably and good enough to accommodate it, else it will end up leading you in to risking your investment by using money meant for your basic needs to buy Bitcoin, this issues about buying the dip even in our ongoing Dcaing has been addressed over and over again. Undoubtedly, while the dip offers buying Bitcoin at a discounted price or cheaper price compared to buying from it's previous highs, getting overly excited about it can be very problematic because you will end up buying more than you should have and that is reason why preparations must be made for it if not forget about it, for our own good and best of interest focusing on the DCA is also a good way of building a good portfolio it will only takes time which is better than being carried away by the dip and put our investment in a risky corner by investing more than we should have there by struggling to sort out our basic needs. But if the appropriate preparation has been made it like having a separate fund, it is also good since it wasn't a primary strategy but a secondary in your accumulation process.
Buying aggressively during DIPs surely requires preparations like making available amounts for buying when the price DIPs but there is a statement you made which i am not comfortable with and that is saying if one gets overly excited buying at cheaper prices that they can end up buying much more than they needed to, but to me there's nothing wrong if you over accumulate due to the fact that you bought more bitcoins when the price was cheaper. Our objective of investing in bitcoin is to own more bitcoins as we can so even if we acquire more than enough it will still be of advantage. Focusing on the DCA don't mean you should not buy more when the price DIPs, you can buy and still continue with your DCA accumulation so buying aggressively during DIPs won't cause any problem to your investment so far as you are doing everything at the disposal of an amount that is available for use.
