An aspect of DCA is that you can take affordable amounts out of your budget (income) each week or whatever might be your frequency, and so you won't necessarily be overly inconvenienced by the amount that you take up, even though over a long period of time, the amount that you end up investing into biticoin is likely goint to end up being a lot of money - even though each week it might not feel like very much.
From a post I just left a comment on before this one, the OP said that DCA strategy is only designed for people that have large amount or sufficient amount in their account, they don't understand very at all that DCA can be used by anyone just like you have explained, it is chosen by investors depending on how and when they get a paycheck, it can be daily, weekly, monthly pending on how frequent the person wants it to be. I agree with your definition.
