Personally, I think that setting up systems to try to buy BTC every week is important, since I believe that buying BTC should be considered as an important thing - yet I can see that other people might not feel that bitcoin is at that level of importance for them and they might even be spending money for various self-improvement systems and ways to earn more money in the future and other reasons that might improve their lives better than merely buying bitcoin, so they choose a more spread out BTC investment schedule. There are balances with these kinds of matters for sure.
I agree with you, everyone has a different lifestyle and has different thoughts. In the investments that are made, sometimes each other has differences where someone is more active in buying gradually every week, some prefer to buy every month or even in every Quarter.
There are also those who do not want to spend a purchase fee every week because if they routinely buy every week then they will spend a fee 4 times a month but if it is done once a month then they only pay one fee for each purchase made.
However, if his job is a farmer, of course he will make purchases every quarter because farming is harvested once in 3 months since it started. For that you are right, everyone has a different way of investing in bitcoin. I know a farmer on social media, he is so confident in Bitcoin that he has been buying bitcoin for almost 3 years with execution every Quarter. He continues to accumulate bitcoin every time he has money from farming.
So in a different way but everyone has a big target in bitcoin, which is to save it and have a lot of Bitcoin in their wallet. Regardless of the accumulation method, it is still one direction, namely holding it for a long time.
As for fees, it's not a problem, but as you said, sometimes it's really annoying.
