That is true, I think one of the most efficient way of buying bitcoin should be on a weekly basis, which is why I try every possible means to figure out my cashflow and try to adjust to my weekly expenses and to ensure that I’m able to buy and and maintain my consistency of buying on a weekly basis, and also I think focusing on regular buying of bitcoin is just more efficient instead of waiting for an unprecedented dip that would make us mix out on opportunities.
Yeah DCA strategy is the most suitable and convenient strategy to accumulate and invest in Bitcoin but what I don't agree with is when you're saying Buying on a weekly basis is the most suitable DCA investment method. I don't think it really matter whether you buy weekly, daily or monthly what really matters is buying at your own convenience and sticking to your plan to achieve your goal. One of the major reasons of DCA strategy is to try and reduce the effect of market flunctuations so whether weekly, daily or monthly your will achieve the same purpose.
Also we all have different paydays so you will set your DCA plan to the one that suits your payment time to avoid inconvenience which may affect your plan.
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.
