The target is always moving, and even our situation is changing.. so how are we going to be able to tell any other member how to manage his BTC allocation in light of his own particular individual circumstances? as those circumstances are evolving. Even in the beginning a guy is likely spending many years accumulating BTC, yet he may also be developing job skills so he can earn income, and there could be questions about whether he buys BTC or if he might spend a certain amount of time and money to build certain life-time job skills, and the answer is not going to be completely clear, and surely the answers might be more clear after the guy has gotten a certain level of education and/or job skills and is applying his job skills to earn an income and to put a certain amount of his pay into bitcoin, so then how many years might he be able to put money into bitcoin, and then once his bitcoin gets to a certain size does he keep putting money in? What if he is not satisfied with his job and he concludes that it might be worth it for him to change job skills and/or even take from his bitcoin to go down that job development path... and I am not going to say that the answer is going to be clear and there may be more than one correct path.
The best thing we can do is to take the time to study ways how to manage our finances since we have decided we want to accumulate Bitcoin. A person might have looked at the current price now, done his research, and concluded this is probably a time when Bitcoin will be much more affordable for him. So if he makes plans to increase his income, perhaps going to study or getting a job. He can still be comfortable investing in what he can afford at that particular time rather than pausing his investment till he achieves the objective. And we all know that there is no certainty if his ambitions will be successful or not. That does not mean the initial plan was all in vain. It could take a year or more to get back on track, but we should understand that before the investor made up his mind to start investing, I believed there was a source of income he had. That source can still be used to buy Bitcoin even if it's a fraction through his DCA method even if he wants to accumulate more but with time he might get a good job that will help him achieve the desired Bitcoin goals.
