There is no beed emphasizing too much on the benefits of having a large Bitcoin reserves and it potential profits merging compared to having just few bitcoin, i was DCA with almost 100% of my monthly income before, because have hard free supplied of almost everything and leaved in my parent house, so it was so easy for me to put down all my earning into for my Bitcoin accumulations for some time almost 2 year accumulations with 100%all in funds that speed up my accumulation process, and within that time i have hard series of profits increases in proportion to my total accumulated amount of Bitcoin.
But few months ago i started living in my own apartment, and since then my Bitcoin accumulation has dropped below 30% of my monthly earning,s, and taken records of my profits merging within that space of time, it can't be compared in any way with what I use to earn as profits when I was all in 100% monthly, which is normal considering the amount I am investing in Bitcoin at the current stage.
But all the same, the DCA approach has become one of the most useful Bitcoin accumulation tools that have helped many investors to be able to accumulate Bitcoin all the way down while taking chances in the various discounted prices presented by Bitcoin from time to time.
I can get the mental picture of what you are saying and sometimes trying to increase your DCA level always ended up into wants or needs since you didn't spare some money or reserved some of it to back it for the next month expense before your monthly salaries comes in always put you in a tension. Do I say had ones experienced this as well but, that doesn't stops you from DCA'ing since you are yet to be in a family mood like some of us here who have kids that are really on our neck trying to make us got distracted with our DCA percentages.
That is why to always keep your DCA amount increase or a regular basis looking for additional cash could also help to retain that percentages you were having before ( That is to say, instead of dropping from 100 percent as previous alternative work could had been more better) although it's not a compulsion but just trying maintain your previous standard until you got to your desired point of accumulation.
