DCA does not mean that the average purchase price will always or consistently decrease. If you can buy at a price lower than the previous average price at the time of your purchase, then the average cost will decrease. But if the next few purchases are above the previous average price, the average will increase again. The job of DCA is not always to reduce the average price, but to invest regularly according to your ability and not rely on market timing. Although I agree with you when you said consistency.
Another thing that people make the mistake of DCA does not eliminate the guarantee of loss. Of course, Bitcoin is a strong long-term asset and at the same time it is quite volatile. So if someone sells during a long period of price decline, he can face losses even if he does DCA.
DCA is just an easy way to accumulate Bitcoin without putting pressure on your self most expecially for low income earners because with the DCA strategy they don't need huge amount to invest with as they can gradually be accumulating consistently and persistently using what they have as their discretionary income, using DCA doesn't guarantee profit even holding Bitcoin for long doesn't also guarantee profit as nobody can predict correctly what will happen in a long run, the DCA strategy only help in accumulating Bitcoin regularly without also waiting for a price Dip to accumulate and it's preferably for all investors and those who want to accumulate Bitcoin and hold for a long time.
DCA increases the chances of making a profit. I don't want to be a pessimistic investor because instead of depositing the same amount of Bitcoin every week, you should increase the amount of Bitcoin deposited as your income increases. The average value that the portfolio shows through frequent purchases will have a higher chance of getting a high profit after 10 years.
Some investors are not relaxed about not taking financial pressure because many of the investors may be poor. For them, DCA method is best through discretionary income. There is no guarantee of profit but the possibility of loss is also low but I give more importance to reducing the average price in this long journey because during periods of price decline, increasing the amount of purchases increases the Bitcoin holding and reduces the average price.
The DCA does not prevent the possibility of a loss especially if the asset continues to lose value over time. What the DCA does is to reduce the impact of such loss in an investor so that the investor don’t get to feel it that much since he did not invest everything at a time and also considering that before an investor made such an investment he also might have sorted out his primary financial needs and the money left with him after doing that is what he uses in buying bitcoin gradually with the DCA and HODL.
