With limited financial capabilities, it is difficult for small investors to invest a large amount in one purchase, hence DCA comes as a solution for investors to increase the size of their portfolio slowly but steadily. I think it's not only small investors who do this, but big investors also do the same thing, but maybe the difference is that the amount they put in is bigger than what a small investor puts in.
This is the easiest way and the best option, especially for me personally this is a very helpful way. Especially I do this for a very long term, slowly but surely with this strategy I increase the amount of my portfolio every week.
Small investor will face difficult for accumulating in bitcoin one day later when raising to higher price, such as with $10 investment still worth right now by daily accumulating seems difference one day later when bitcoin raise to higher price above $100k. So during get great an opportunity don't waste time for accumulating in bitcoin and keep reinvesting although with small fund due bitcoin price still under $27k and amount with $10 in daily day for accumulating worth for upcoming time when bitcoin will raise to higher price.
Don't think what happen later if have chance for accumulating right now although with small fund due saving fiat have inflation but saving or investing in bitcoin will increase or our amount investment assets in the future.
