It all depends on the ability when we are ready to do it weekly then it will certainly be very worth it to do but in some cases, especially for those who invest with the income funds that are owned from the salary every month then I don't think it's too imposing also when they don't make efforts to buy weekly and divert to monthly it is also still very worth it.
But when talking about the context of beginners in this case, sometimes the enthusiasm is still very big to try to collect bitcoin as much as they can so that per week it will not be a problem for them because after all they are excited to do it so they don't think too much the most important thing is to buy. This condition is normal especially since we must have felt the same thing where we never thought several times about buying when we were beginners so this kind of enthusiasm is quite good even though in some cases the intensity of purchases has decreased slightly for several reasons, especially as an evaluation but I think when we become a beginner, the excitement and enthusiasm in purchasing is very large indeed.
When a person is managing investments through DCA method, he should be given full freedom to decide whether to do weekly DCA or monthly DCA if he does not seek advice. He can take decisions based on his ability. If he is monthly salaried then he can choose monthly DCA or if he is weekly salaried then he can choose weekly DCA. Again he can decide the time of purchase depending on his decision ignoring the time of salary. He can manage his investment depending on his personal opinion keeping in mind the characteristics of DCA in investment. I urge you to give him full freedom as to how often he buys. But if one plans to make frequent purchases, he should be advised, as frequent purchases will increase the amount of fees. Although I use and love DCA monthly, a person should not buy more than 4 times a month. It is better to buy at most 4 times a month or less. Here you can take decision independently.
