If talking about the issue of agreeing or not, of course I would also prefer to make regular purchases without having to make aggressive purchases so that we still feel comfortable with the purchases we make and do not feel burdened by it but in the end if someone really wants to do aggressively then as long as they are able to why not, but that does not mean all have to do that.
The key is back to finance because after all we have to measure the capacity we have in this case especially for investment matters because this is not just a toy to save money but there is hope that with the investments we make now there is hope that we can get optimal results in the future from the results we get from what we sowed before.
In the end, we are not necessarily going to agree how aggressive a person might want to be, and surely the level of aggressiveness is always within the scope of the person to figure out how much he wants to balance his investment into bitcoin versus various other competing places he can put his money in regards to current consumption and/or even other investments and/or having some assurance that if he invests less aggressively, then he would be able to keep more cash in reserves. There is no exact correct answer, yet anyone could end up considering that he is merely being aggressive, and then he ends up overly doing it. No one is going to rescue another person when he has made the mistake of being overly aggressive... so you could be correct that it might be better for some folks to make sure that they are not being overly aggressive and perhaps even having some extra cash cushion available so that they are less likely to end up being overly aggressive.
Otherwise there are some folks who choose to be less aggressive about bitcoin because they are not sufficiently bullish about bitcoin, so they end up erroring on the side of keeping extra cash. These are somewhat individualized choices, yet they likely could have pretty major differences in outcomes for the person who could have had invested $100 per week, yet he chooses $10 per week because he wants to keep extra cash available for other priorities that he has.
True, because everyone has their own views in this matter so that surely in any case including in the method of purchase made everyone has their own stance and it becomes a fairness because everyone must have their own buying scheme so that we cannot assume that agreeing or disagreeing with something becomes a benchmark because in the end this is again just a choice in the end and we cannot assume we are right and others are wrong and vice versa because everyone has their own considerations according to the conditions and circumstances of their financial aspect which includes all aspects of income, expenses, reserve funds, funds for investment etc. But whatever it is actually will not be a problem if we can accept each other including in terms of input and criticism especially if the goal is to perfect our shortcomings then I think all will be a good thing because indeed our goal is to argue with each other here to make our views broader from all aspects in order to make the investment we do run as expected.
There will be a lot of people who are like your example but sometimes people who usually do that try to take a deeper approach like saving about $10/week or even more but their goal is to try to collect more consistently for a long time. This is most likely based on the reason that sometimes they try to do this so that they are less burdened and minimize if in the future they are in a bad financial condition they can still strive for that consistency because $10/week is not too burdensome.
