I actually suspect that I_Anime does not even have that good of finances in place, .. but I don't know, yet these would be the kinds of considerations that a newer guy into bitcoin would have to attempt to take into account and try to plan around so that he can control the amount that he sells or does not sell and to consider if there might be some price points in which it does not make sense for him to continue to DCA.. and either just to hold those funds or maybe put them into other assets.. which are all trade offs, in which some guys will just continue to accumulate BTC for more than a whole cycle before getting into any ideas of selling any BTC or even discontinuing their DCA... but part of the problem is reality.. and the reality may well be that the job of any newbie is not really paying very high wages as compared to the appreciation of their BTC (at least the appreciation that may not end up being sustainable)
While most people now make money for a living, there are few people who can earn some extra income beyond a job or fixed income. What you suggest is certainly valid, but most people by now think that cash is the only thing that matters to them. That's basically why they convert from all other currencies or from bitcoins to cash. Because of this they cannot implement any kind of plan, because the cash withdrawals are spent on life or livelihood.
Every man needs money for his living so man engages himself in various business jobs so that he can provide his financial support.Whether people have a job or a business, they have a certain plan to set aside or insure some of the money they get at the end of the month. People should understand that if they deposit their remaining money in bitcoins, they can make more profit from bitcoins instead of cash. Bitcoin investment is easiest for those who have an additional income opportunity as they can invest in DCA method if they want. Anyone who invests in Bitcoin this way gives everyone the opportunity to deposit Bitcoins weekly or monthly. People who have a job get paid a fixed amount every month and not everyone spends the full amount of that salary. If they invest that money in bitcoin and if they accept their bitcoin investment as a bank, even if they are able to manage it for a long time, they will be able to succeed one day.
sometimes , depending on a single stream of income most expecially as an average salary earner might not give you the luxury of being consistent with your DCA methord most expecially in most countries where civil servants don't get paid on a regular bases and thier salaries can be withheld for months before paying which could be a serious setback that might possibly hinder the effectiveness of your DCA routine but knowledge and discipline entails that you understand the peculiarity of your Financial circumstances and make proper planning which might involve looking for alternative streams of income that will stand as a support system in times when issues might sprout out regarding how consistent you receive your pay.
