I want to correct one impression that you are making here that many people are utilizing the DCA method because it is easy to use. No that's not the case, rather many people are making use of DCA strategy because it is more effective way of investing in bitcoin as it reduces the impact on the capital invested should there be a sudden drop in the market. The DCA method makes the capital outlaw not to reduce drastically when there is a sudden decline in the bitcoin market. This is the more reason why many people are comfortable with using the DCA method of bitcoin investment, not because it is easy. Also the DCA method makes it easier for people to buy bitcoin at their own pace according to their financial level. The truth is there is no method of bitcoin investment that's difficult to use.
You are literally contradicting your own explanation. How about I tell you that I prefer to use the DCA strategy because it is easy to use?. At least, I don't have to monitor Bitcoin price for an entire 24 hours, to observe when there is a dip(for those who only buy the dip). Bitcoin investments, especially to those who are new to it, shouldn't be explained with too many terminologies and complexity, but rather as smooth and easy as possible. Just as you've pointed out, "the DCA method makes it easier for investors to buy Bitcoin", which depends on their financial capabilities (source of income). It's always a continuous process, that doesn't need too many grammer or math solving to explain.
