Isn't the question regarding the extent to which a guy's income and/or expenses have become more complicated based on his life situation rather than trying to presume exactly the effect of being married versus being single?  Of course, there can also be guys engaged in businesses, and some businesses are not very complicated or involved - maybe a couple of times a week the guy goes and sells some products (as a side business or maybe he teaches some skill that he has or works as a private consultant), yet there might be guys who have several employees and a variety of relations with vendors for products and/or services, and the more complicated the situation, then the more back up funds he probably needs to have and we don't even necessarily need to assume that his income is going to be so low that he is not able to invest, even though many businesses will be less profitable (and even fail) in their earlier years, so the point is more likely about complication of his finances and/or relationships rather than something like whether he is married or single.  

I suppose I am not disagreeing with your point about being married bringing more potential complications, yet I am objecting how you described being married versus single in such a presumptive way as if a single person is still not going to have obligations merely because he is single.  I don't necessarily disagree with you in regards to the extent to which some decision making might become more complicated with a spouse to the extent that there either might need to get input or at least at minimum the guy might have extra responsibilities in regards to parts of his income that would either go into the joint relationship and/or to support the wife.. and surely there could be situations in which a spouse brings extra income and/or potentially brings more income so the financial aspect is more of a benefit rather than a burden.  Guys have to account for these matters, and we should not presume too much about them unless maybe describe our presumptions.

So for example I could say that I am going to compare two different guys and they have some aspects that are similar and they have some aspects that are different.

They are each in them is in his mid 20s and each has some technical schooling but not university level, so they work as electricians and do some general labor as well... and so they are in similar kinds of work and maybe even have some similar hobbies.. so they have a similar income.. let's say around $25k per year and they expect that if they work hard they can get promotions and raises and perhaps expect 5% to 25% increases in their income depending on their contributions.

One guy has a spouse and the other doesn't.  Maybe the spouse also works around 15-25 hours per week, and maybe she makes around $200 to $300 per week that largely goes towards her own living expenses and so in that sense she is not really contributing, but she is also not really costing anything extra since the guy still pays for housing that is similar to the single guy and maybe if their housing is extra then maybe it costs a bit more and the extra come from the woman's income.. .. and if they are thinking about building a family, they are thinking that she might be able to keep her job, since it is ONLY a part time job that has a sufficient amount of flexibility..  

So I might not know what level of complexity the wife has and if she is costing extra or not.. since she would bring both costs and benefits, as is the case with any relationship.. and sure we could make assumptions, but we shouldn't make assumptions that the wife is full of costs and without benefits, and sure, maybe we can assume that many early businesses are not very profitable, but just saying that a person owns his own business does not necessarily paint the whole picture since we still have to get back to the questions regarding income versus expenses and the more complicated situations may cause more challenges and may even take away from a guy's ability to invest into bitcoin, like you mentioned, but maybe the guy got married in the first place because he had gotten some promotions and he started to earn enough income so that any extra expenses from being married was not going to take away from his other goals, such as investing into bitcoin.
 

I probably don't need to repeat myself, since I largely already made my points a couple of times, yet you keep repeating the same categories that are not very fit for describing what we might need to take into account... Let me just attempt to spell it out a bit more clearly.

Marital status ==== is a sub category that is a part of what might contribute to complexities in terms of income/expenses and also decision making.. it is not that great of a category to help to frame what a person needs to think about when investing.

age = this is one of the sub-categories of investment timeline - so sure it is important yet it is only one of the factors that might affect how a person might consider his investment timeline.

financial stability - I am not sure what you are trying to get at here since financial stability has a lot of factors in regards to income and expenses and including cashflow management practices, so sure a person first of all has to figure out the extent to which he has discretionary funds in order to invest, so having discretionary funds can get the investment started, yet continuing to invest might have to do with how much confidence the guy has about future income.  I doubt the term captures what needs to be considered since it is likely too broad if a person is merely thinking about the extent to which his finances are stable or not.. He is not required to have stable income to get started, but to continue investing he would be advantaged by having stable finances, even though it is not required that his finances are stable.. he works with what he has in order to make sure he understands that he is investing within his discretionary income and also that he has back up funds in case he might make some mistakes or that some future expenses might exceed his future income.


Amount of savings - this sounds like a sub-category since when a person comes into bitcoin he might have savings and/or investments that he would take into account in terms of how he might invest into bitcoin or how he might manage his back up funds.. so sure, a guy can start at a certain status and then either maintain some of that or build upon it and/or sometimes reallocate some of what he already has into bitcoin.

Where BTC is in the cycle...   I doubt that trying to figure out the price is important as a category, especially for beginners, yet you surely want to emphasize that kind of thing while at the same time you ignore your own history in that regard. .. when you came to the forum in 2016, you were likely busy learning about bitcoin and trying to figure out how to time the market rather than just getting started buying bitcoin..  So then it ended up taking you right around 3-ish years to buy bitcoin and to buy it on the dip.. and you still rationalize yourself as to being smart for doing that.

You could have had gotten started buying bitcoin between $400 and $2.5k for more than a year between mid-2016 and mid 2017, and surely you could have had attempted to frontload your bitcoin investment in order to get towards the lower end of those prices or at least a decent amount of time that bitcoin was below $900 through most of 2016 and really BTC prices did not go above $1k and stay above $1k until about April 2017... so instead you started buying bitcoin in early 2019 in the $4ks and $5ks and considering that you were getting bitcoin at bargain prices, and sure, relatively speaking those folks who got started in bitcoin in early 2019 were also in a good place to front load their bitcoin investment and perhaps have some lump sum buying amounts to get bitcoin at the lower end of the $4,200 to $12k-ish range that lasted for a bit more than a year and a half.

You still did good to buy bitcoin between 2019 and 2020, but you would have had done even better if you had started buying bitcoin in 2016, so waiting tends to be a worse strategy.. and surely there are guys who ended up starting to buy bitcoin in 2021.. so they have to deal with their having had bought at higher prices than those who started buying in 2022 and 2023.... but still there seems to be an ongoing repeated pattern in bitcoin in which people wait and/or they try to time their buys rather than ongoingly buying bitcoin and building their stash for 4 years or more... Of course you don't need to build over the whole 4 years if you front load your investment.. yet surely if there is a guy who might have $30k to buy bitcoin right now, he might want to consider dividing that up into three parts $10k to buy right away, $10k for DCA and $10k for buying on dips... even though the dips may or may not come.
