It all depends on the amount of bitcoin the person has accumulate over that interval of one year before you begin to talk about making of profit. If u do not have a sizeable amount of bitcoin in your portfolio you cannot be able to make this profit you are talking about ,especially if you are doing DCA it will take you time to accumulate a reasonable
amount of bitcoin.
The method of collecting Bitcoin to get a larger amount varies from person to person, although the one we see most often now is to use DCA with a certain target time period. Because to achieve a bigger profit target, you definitely have to have a fairly large amount of Bitcoin ownership and that cannot be denied by everyone. That is why most people always pay more attention to their Bitcoin holdings portfolio than others because in Bitcoin everyone can make a profit as long as they have enough patience in collecting it and also have a fairly large amount in their own portfolio.
Basically those are the investors who usually do the DCA in bitcoin to accumulate the bitcoin throughout the bear market. Those are the people who will then sell in the bull market and gain maximum return on Investments.
Also I will like to emphasis that it is not necessary to accumulate a lot of bitcoins as even a person with a moderate income can buy some portion of bitcoins and that would be enough for him to gain good profits with respect to his investment of course.
The point is that you need to first calculate your total portfolio which you are willing to invest in the crypto and in that portfolio 50% of the amount should be in bitcoin.
