I guess I am trying to say get started and learn along the way, and maybe after accumulating BTC for a year or two, there might be some justification to start to adjust the strategy based on how much BTC you have been able to accumulate and based on your other financial matters, and so in some sense, it can be difficult to come straight into an investment (something like BTC) and not take a bit of time to establish a position, and since Wind_FURY was referring to poor people, so for poor people in particular there might not even need to be too many adjustments along the way, just keep buying as aggressively as you are able to without overdoing it... but the thing, even for poor people, there might be some recognition that after a year or two of accumulating BTC, the BTC stash might be starting to get relatively large as compared to other investments (or savings) that might have had previously been done.. .. yet also it could be that the amount put in is still less than the value of the stash, so there could be some variations in regards to how to consider and look at the stash depending on how much had been put in and the extent to which the stash may or may not be in profits... although some folks might get distracted by merely being in profits, so some learning might need to happen in regards to how large of a stash might be considered to be a large enough size in order to start to consider some possibilities of changing strategies that go beyond just continued, ongoing persistent and consistent buying of BTC (perhaps weekly).
IMO, if an investor choses a buying strategy for his stash and cannot or couldn't eventually meet up with the buying due to his financial status then a little gap could be added in the time-interval he uses for buying for example
If it was initially a week it could be set to two weeks , if two weeks a month could be chosen.
I will suggest a max- of one month interval
While this is done learning could also be taken along with it
