Many of us here already knows the importance of using the DCA strategy to invest into Bitcoin. With DCA, investors get to buy Bitcoin at different prices (in decreasing or increasing order) so that they don't miss out the opportunity to buy at a certain low, for example if the price is falling, most investors might not just want to put in all their money to buy but would rather invest bit by bit while watching for the price to dip more. Some people too invest using DCA strategy because of how their income is paid, if they receive monthly salary, they can only invest after they get paid.
The reason for using the DCA method to invest bitcoin is not just about the price of bitcoin ( increase or decrease), the main aim for DCA method is for investors to be able to invest bitcoin easily without trying to save some money to buy bitcoin because this is even waste of time but the essence for DCA method is for investors to invest with the money they can afford. Some people do think to invest bitcoin you have to get some fine amount of money to invest but the DCA method have proved it wrong that people don't have to get plenty of money first before investing in Bitcoin.
I totally agree with you on this one and in addition to what you said, DCA method can also make an investor to consistently accumulate bitcoin without timing the market or waiting for a DIP. If an investor can stick to the DCA method believe me he or she we accumulate a good portion of bitcoin to hold for the long run for 4 to 10 years, instead of waiting for DIP.
