The bolded part of your narrative can be very misleading considering the fact that newbies can as well access this thread, since you will not be buying a whole Bitcoin the current price doesn't make it high or expensive for any investors to make purchases of Bitcoin, with dca strategy fractions of Satoshi can be bought with as little as you can afford either weekly or monthly irrespective of the price point at different intervals, there is no certainty or guarantee to backed up your claims that there will more drop, why even waiting for a drop before accumulating Bitcoin? It can be a total waste of time as you may not be able to see your expected dip, but with dca you are already in the market on time without any form of timing the market .
The price of bitcoin is not high for any investor who intend to purchase Bicoin, it's important to consider that buying bitcoin doesn't require purchasing a whole coin. Waiting for the price to drop before buying bitcoin might not always be the be best approach especially if you want to keep growing your bitcoin stash. The question is dip might occur but does it suit your desired level?, Using a DCA strategy is an approach that eliminate the need to wait for a specific price drops that may never come, ensuring you're consistently in the market without the stress of market timing. With a DCA you can acquire Bitcoin at various price points regardless the market situation. This way, you can invest consistently and avoid missing out on potential opportunities that align with your investment goals. DCA allows you to purchase Bitcoin at both high and low prices, ensuring you stay on track with your investment strategy.
Of course, there is no rule or compulsion to buy a whole bitcoin, or I mean 1 whole bitcoin, it is too expensive for most people and also in my opinion not very effective to do unless you really have a lot of money, because most investors especially those who have a medium or below average financial situation always accumulate slowly where they already know that over time they benefit from the increase in price that occurs.
Buying when the price is decreasing or when it is correcting is indeed a good idea to execute, but yes I agree with you that it is not always an effective idea to do when one wants to have a larger amount of accumulation in a faster time. The problem in this case is that when we are too focused on waiting for the moment of decline to buy then surely it takes time to wait, while we do not know for sure about when bitcoin will experience a decline and to what level the decline will occur, meaning that although the idea is good but it can create delays in the accumulation of bitcoin that we have planned. So far DCA remains the best solution approach to bitcoin accumulation that can maintain consistency in terms of allocation, minimize the possibility of delays in allocation, and the following can also minimize the sense of worry.
