I don't think if what you said is correct about beginners understanding of the market. As long as the DCA strategy is concerned a beginner doesn't need to understand the market before they can start with DCA strategy. Moreover, they are not timing the market so what's the need of trying to understand the market before they start using DCA strategy. It is those that may want to buy bitcoin using buy the dip strategy, I believe they are the people that needs to understand the market before they can buy since this strategy requires timing the market.
What I mean by understanding the market is related to beginner psychology. A volatile market can influence the psychology of beginners who are trying to apply a buying strategy according to their plan. You can easily do DCA, but what’s your mindset when the market situation might make you panic? Understanding the market is important for staying calm while sticking to your long-term plan, not just buying along and selling when it drops.
Smart investors aim to literally use Bitcoin price volatility correctly.
Do you mean that you should try to make more profit by taking advantage of market fluctuations?
If that is what you mean, then your point is moving towards trading. But if you mean by the quote part that if you buy regularly or do DCA, the market fluctuations will naturally average out or you don't have to worry about market volatility, then that is fine. Because I believe that if an investor focuses on buying regularly, he can cleverly average out the purchase price without stressing about volatility.
DCA method is the mindset where an investor can acquire a large amount of Bitcoin holdings
I don't think so. How much someone can or will accumulate depends on their income, expenses, emergency fund, discretionary income, time frame, and patience. DCA helps them make regular purchases, they don't have to worry about prices, they can buy according to their ability. But it can be quite difficult to say that just by doing DCA they will be able to accumulate a large amount of Bitcoin. Because if you just do DCA without considering your cash flow, financial situation, and think that my savings will be the largest, then you haven't fully understood yet.
