There investors that may not want to go in all at once, they may decide to keep some percentage of there discretionary income and them use the remaining percentage for buying the dip. As per being a low coiner ,it also depends on ones cash flow for someone with a good cash flow management that may have a good amount of discretionary income after sorting out all there expenses may decide not to put all there discretion into buying bitcoin at once they can decide to use some percentage to DCA and the remaining percentage for buying the dips.
I think that waiting for a fall is not the right decision. Because the market is very volatile, you can never tell when it will happen. If the fall you are waiting for does not happen in the market, how will you buy? You will miss many buying opportunities. If you have money, invest it. It would be best. Because
Suppose you are saving money to invest. If the Bitcoin market does not fall in the last 1 year and the price of Bitcoin reaches 150 thousand dollars, and if the Bitcoin market falls after 1 year and the price of Bitcoin falls from 150 thousand to 140 thousand dollars, then you have missed many buying opportunities. For example, the current price of Bitcoin is 112 thousand dollars. You did not buy from 112 thousand to 139 thousand dollars, you have missed these buying and buying opportunities. If you had continued to buy using the DCA method, you would not have missed the buying opportunity. So never wait for a fall and continue to buy continuously.
