I personally prefer weekly DCA for newbies in order to encourage active buying of BTC, yet weekly buying still might not work for everyone, and surely someone who has $2k per month extra is going to be in a more flexible position as compared with someone who might only have $500 per month or even $50 per month extra.. yet decisions about whether to actively invest every week or every month is not ONLY based on their cashflow, yet when the amounts get to be really small, there can also be some issues with fees too.
Well, it's quite true and just like i said there's isn't anything actually wrong in buying monthly so far the input is consistent just that I also prefer the weekly compared to the monthly besides I'm also in my accumulation stage and the weekly buying method could improve the efficiency of price entry (though not always but most times it proves it worth) and about the fee I think that could also be put into consideration but taking 4 inputs/per month shouldn't be to much to pull when the need for consolidation arises... though if compared to single input/address its quite preferrable over 4inputs/month but still there will still be a need to consolidate so I think the fee difference shouldn't be too much so far the inputs isn't much.
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.
