Maybe if indeed when we enter the total monthly investment expenses plus our needs for 1 month it will seem to be misleading but in this case I personally distinguish the calculation notes to make it easier for myself to manage the finances that I do.
For example, this month I have an income of around $300 a month and I spend $200 for personal needs and around $50 to buy bitcoin. I will make different notes for investments where indeed in the ledger the financial records will definitely remain $250 as this month's expenses but when talking about bitcoin we definitely need another record where there must be a record in the expenses we make for the purchase of bitcoin so that we know how much we have spent on bitcoin while we are here and that in my opinion is important as a consideration and as a belief that in the end being in bitcoin is profitable so that we don't not know how much of our money we spend on bitcoin and how much profit we can take.
But indeed in the end maybe this depends on what we are comfortable doing because the most important thing in this case is that we don't mess around with the way we manage money regardless of the different ways that are done and the mention of something in the end the goal remains the same, namely bitcoin investment.
In your example, if a guy is buying bitcoin with 25% of his expenses (50/200), then after about 4 years, the guy would have invested a whole year's worth of his expenses into bitcoin.. .So that would not be a bad place to be in terms of building a BTC holdings that has greater chances of getting him to fuck you status or some kind of a status in which he can start to employ sustainable withdrawal.
I wonder how important your ideas about profit taking is? Sure we want to be in profits or even presume ourselves to be in profits with the passage of time, yet if the guy in your example continues with his practice of investing 25% of his expenses into bitcoin per year for 12 years, he has therefore invested 3 years worth of his expenses into bitcoin at the 12 year mark. So then maybe the other question might be how bitcoin ended up performing over that time in order to allow the amount invested to grow at least with the cost of living increases and perhaps more than that. ... even though there are no guarantees...
So I am not necessarily going to presume regarding how much profits the guy might be in, yet I would suggest that the value of his holdings may well help to guide him in regards to whether he needs to continue to invest/accumulate bitcoin or if he might bd ready to start to employ some other strategies that might either be just maintenance or perhaps getting into various kinds of withdrawal practices, whether that would be
time-based withdrawals and/or
raking kinds of strategies.
Surely we make our own assessments regarding where we are at and how we might want to replace and/or supplement our income with bitcoin withdrawals if we happen to get ourselves into such a position.
okay indirectly you are saying that maybe in this case the accumulation is too big but as long as we are able then why not because after all this is not about our own ability in the end right? say indeed it is 25 percent of total income if indeed they can cover it then I think it is not a problem because after all when we are in something (including in bitcoin) then indeed we must be able to consider for some period of time ahead and again in this case I prefer to divide it periodically so for 12 years it is too long for me so 5 years is enough and when you consider the performance of bitcoin during that period (I want to take 5 years) as the timeframe I'm using right now and with the economy getting tougher in the end it's also predictable and we're also not likely to just stay at $300 for personal income because when the economy goes up then in this case the salary in our job usually follows in order to be balanced and that's been happening in the last few years so in the end when we can afford to make 25 percent of the initial budget then it's not a problem as long as we're willing to accept the risk.
In addition, returning to the initial discussion about capital in the end this is also important because investment can also be a business and we must know how much we spend on accumulating bitcoins that we buy from the beginning to a certain extent consistently and how much profit we get after we invest in that period of time. It becomes an important part because after all we are in bitcoin is for profit and financial freedom so the profit factor even though it is only a figurative expression because the bitcoin remains the same only the value is different must still be considered.
