qI agree with you that buying at the dip should be done with some unexpected funds that comes our way which we don't have plan for, and whether they come or not, our regular DCA continues. What I do is that whenever, I am given a bonus at work or traveling allowance, training allowance, or some incentives for motivation at work. I keep such funds without touching it so that if it happens that bitcoin price dips, I can take advantage of the dip and buy more. And if it happens that I don't have any extra funds apart from my monthly income, my regular DCA is what I do and focus on more weekly
When it come to accumulation of Bitcoin, we should always keep our DCAing constant irrespective of the market conditions. Expecially those of us that can't afford to purchase large quantities of bitcoin. Because if one have the mindset of always waiting for the dip before accumulating he or she will only endup missing out or having small quantities of bitcoin in their portfolio.
That's why is better to save some funds (which is known as reserve funds) in case any dip occurs one can purchase the dip with the use of reserved funds, and he or she can choose to spread it out or go all in with the reserve funds like lump-sum purchases.
And there are investors who made buying at the dip as there Bitcoin accumulation strategy and what if the market did not dip will they keep waiting? It will be better they use the DCA strategy and also buying the dip strategy together so that the DCA strategy can help them accumulate more Bitcoin at different price level weekly or monthly and also buy when the market is at dip with the help of their reserve fund. But if the investor is still a low coiner the buying dip strategy alone won't be a good Bitcoin accumulating strategy.
There may be absolutely no need for a brand new investor, and maybe someone in their first few years of buying/acumulating bitcoin to employ buying the dip strategies rather than sticking with straight-forward and regular DCA (which may well not even be sticking with any particular amount of BTC, but instead figuring out how much BTC to buy each week from the amount of disposable income that he has for that particular week, whether that is $100 or $10 or some other amount).
Yet of course, there might be some psychological reasons to hold some money aside for buying the dip, but it may or may not end up paying off because we cannot rely on dips actually happening or even happening to such an extent that it is even going to make much of a meaningful difference in a person's bitcoin journey, especially if the person might be new to investing and ONLY investing around 10% of his/her income so it could take a whole 10 years to have 1 years of income invested into bitcoin.. so it is difficult to understand and/or appreciate what value might have had come from buying the dip rather than just buying regularly and not changing behaviors based on factors that might be difficult to measure the extent to which there might have been any kind of advantage to straight-forward DCA.
On the other hand, any of us might come across periods in which we receive extra money for a variety of reasons. Some people might receive bonuses two or more times a year or there could be other times in which extra money comes available, and surely there could be some thoughts about lump sum, buying the dip or just incorporating that extra money into DCA... and maybe if the extra money just gets used right away for BTC purchases, then that extra money also becomes just a part of the person's DCA system, so I am not even suggesting either choice is more preferable since these are the kinds of discretionary choices that each of us has to make in terms of how aggressive or how whimpy that we want to be in terms of our ongoing bitcoin accumulation -
and there is no correct answer, even though there surely may well end up being a difference between the person who invests $100 per week into bitcoin for 10 years and the person who invests $10 per week into bitcoin for 10 years (because the person who invested $100 per week would have had accumulated 10x more bitcoin than the person who invested $10 per week into bitcoin), but there still is no correct answer regarding what might have been the better choice even though a lot of us may well appreciate having had accumulated 10x more bitcoin, but there may well might have been trade-offs along the way in terms of accumulating 10x more bitcoin, too.. such as maybe the person who invested $10 per week rather than $100 per week ended up having a happier life because he was spending that extra $90 per week on things that ended up contributing to his ongoing current happiness rather than his delayed his happiness.
Each of us has to figure out and make our choices, and surely we could use some DCA charts to see how $10 per week versus how $100 per week would have had played out in terms of the quantity of bitcoin accumulated during the past 10 years, for example.
