I don't quit understand the point you are trying to make because it seems you don't understand much about the use of DCA because from your Statment you seem to presume DCA strategy is only a method that requires huge amount of money before utilizing it because I wonder why you would only use DCA strategy only when your salary is normalized, however I want to inform you that the use of DCA strategy doesn't only involves an investor that has a huge capital but also someone who doesn't have much funds because their is no discrimination in terms of DCA usage.
Perhaps even if you are earning $50 in a monthly basis you can still be consistent on either weekly or monthly accumulation of Bitcoin, for instance since your total monthly funds is $50 you can strategize your accumulation plans to monthly basis using $10 because going above that can easily affect your investment but however if on the process your salary increases or having more other source of income you can then bring it down to a weekly accumulation.
In fact, DCA is very practical and easy for beginners to apply, especially in long-term investments. In DCA we don't need technical analysis because we only execute it when the time comes, for example once a week. If we invest in a year we make bitcoin purchases 48 times a year so we can imagine that we will find the lowest price which may be difficult to do by other means other than DCA. So, if you are determined for the long term, then apply DCA in the investment you make.
I think an income of $50 per month is of course quite a small income, in fact no company pays its employees $50 per month.
My brother there are millions of companies that pay their staffs a monthly salary of $50, $40, $30, $20 in Africa, so when I saw your post about no company can pay it's worker $50 that it's too small, it's possible you are speaking from how things are working in your region.
Most people in Africa are struggling to own bitcoin, taking risks just to own bitcoin, because if you check the living conditions of masses, you will see the main reason why there is many adoption of bitcoin especially by their young citizens is because bitcoin is hope. Bitcoin has become the shinning light they can look up to for a brighter future and better everything around them, and improve their living conditions. People living below $50 monthly salary are still buying bitcoin and hodling for dear life.
