Of course, it is good to assign a fixed amount from our discretionary income into regular buying of bitcoin through DCA weekly or monthly but sometimes this might not be possible because it is not of our own control but based on our expenses that arises in different weeks. If you observe sometimes we might spend more than what we budget for the week due to increase in our needs for that week and sometimes we might spend less due to decrease in our weekly expenses.
In such scenarios the investor might choose to invest $50 weekly but when the expenses of his needs increases, he can cut down his DCA amount to $40 for that week and if his expenses on another week decreases, he might increase his DCA amount to $60. The most important thing is that the investor did not stop buying but continues buying no matter how small he could buy in a week.
Also an investor might have an increament in his monthly income, or has an additional means of income along the line of his bitcoin accumulation journey, he will increase the amount that he is using to DCA in order for him to buy bitcoin more aggressively as long as he did not over do it.
There can also be a case where an investor did not have any discretionary income on that week because of too much responsibility for the week and his discretionary income was exhausted, such investor don't need to worry that he did not buy bitcoin for that week and he will just hodli and buy the next week. Another scenario is if the investor loses his job at that moment, he is to pause his bitcoin accumulation until he gets a new job while he feeds with his emergency funds and reserve for the main time till he gets a new job and continue accumulating. If you have the funds to keep on buying don't stop just keep on buying.
I've always had my reservations with cutting down fat to maintain a process and I'm always of the opinion that you mut not harm your lifestyle in order to contain a new profitable activity, you can do more to make more money and dedicate the extra funds to the new process and in this case investing in bitcoin.
for example, if you are a person who hates working overtime at your work place and you are living fine with it and then you decide to start your DCA journey, you can do it without harming your living standards, you can do as little as taking the overtime duration of work and dedicate the funds solely to your accumulation journey, that way you are able to separate concerns and being very specific with your investment funds and also your accumulation journey would be smooth while you maintain your living standards.
In the case of no overtime jobs, you could even take up a side hustle and dedicate two or three hours a day to it for your periodic accumulation of bitcoin. You should thrive to make more money to cushion a new responsibility so as not to contain the mentality of always having to discomfort yourself in order to entertain every new responsibility that comes your way as a person. The side effects of always discomforting yourself is that you can get fed-up with always being the victim and disengage yourself with everything that brings about much discomfort to you, but when you are always crafty and making more money, you have a lot of fun on the way, sort out yourself easily and your individual effective adaptation quality increases.
