I don't know if I am right but I feel that only the DCA method can be used to invest in bitcoin and build your bitcoin investment gradually, and at the same time build your emergency funds from the left over of your discretionary income for those new beginners who are not earning much and don't have bulk cash available to use in startingtheir bitcoin investment. This is why I love the DCA strategy but if it can be mixed with buying at the dip when you are prepared, you will get a better result.
The ONLY way that you get better results by mixing buying the dip with DCA is if the BTC price actually dips. If the BTC price does not dip, then you do not get better results. There have been many times in bitcoin's price history that it did not dip further, so person's employing buy the dip in those circumstances may well not have had been better off than strictly employing DCA.
Part of the reason that DCA is so effective is not because it guarantees that you will have better costs per BTC and the fact is that you may well end up with higher costs per BTC by employing DCA - yet at the same time, you are able to figure out ways to be as aggressive as you can with your investment amount into BTC from your discretionary income - which is quite a good thing for no coiners or low coiners to strive to get a stake in bitcoin and not to preoccupy themselves with short term moves in BTC price.
Your explanation is comprehensive jayjuangee, and for me I use disposable income to buy on a dip like let me take an example if am using the DCA to buy every week and a dip comes and my discretionary income is like x3 of my DCA what i do is to buy at the dip then i will pause my DCA till i replace the discretionary amount i used in buying at a dip afterwhich i continue to DCA.
Continuous use of the DCA is just for a beginner who doesn't have enough funds or income if not it is good to buy more when a dip happens then you can still continue with the DCA later on. It is good to understand the market correctly because if you do you are likely to make more profit in the long run when you know when to buy in a dip and when to DCA. The more reason why I like the DCA is for consistent accumulation because if you have a steady income flowing, you are likely to own a huge portfolio because there are people who wants to get huge amount and invest at once but some circumstances might arise and you use up the money but if you are someone that applies the DCA, even if any events happens that will require you to spend some money, you can sort it out without touching your holdings.
