The dude is not totally wrong neither is the dude totally correct, DCAing weekly will make an investor grow their portfolio faster than someone that is investing monthly but the things is that it depends on the amount these investors are using to invest so if someone is using DCA method for weekly and they are not consistent or they are not using a good amount to invest someone that is investing monthly will grow their portfolio more if they are using a good amount than someone who is investing weekly. But whether investing with good amount or not the most important is to just start.
DCA buying of Bitcoin can be done weekly or monthly, depends on the Cash flow of the investor. There are investors that received salaries pay every weekend while some investors will have to wait until month ending before receiving salary. The time duration here doesn't matter, rather the key thing is for them to be able to figure out a discretional income from their weekly or monthly salary to be able buy Bitcoin weekly or monthly. what you should also understand is that, an investor that is DCAng weekly and an Investor that DCA monthly doesn't have the same accumulation targets,their goals may be the same but their accumulation targets will always differs and cannot be the same.
My points is ,an investor that's accumulating bitcoin consistent monthly may reached his Over-accumulation target faster than an investor that buys bitcoin weekly because of differences in accumulation targets.
Yes I agree to that, an investor practicing DCA buying weekly with little capital because of financial instability may find it difficult to reach his or her accumulation target while the monthly investor with high capital finds it easy to get to his target at last, Both weekly and monthly investment program are very good programs depending on salary scale at the particular point in time the bottom line of all is knowing why this investment programs are practiced. The main reason for practicing the DCA buying program is to accumulate assets over time and can not be done having profit generation as its primary aim of practicing because we may buy when the price is still high.
