I think years back the DCA strategy was not effective because the price was kinda affordable compare to now and i believe most investors back then where lump summing, I mean back then one can get some numbers of Bitcoin with $5k but right now it's entirely a different case,
That's not true and DCA is not something that just come out suddenly it has always been here right from the day one of Bitcoin, I don't no how you are seeing it because DCA is not like a physical entity that can be developed like that, so is like a theory that has already been on existence, so it was only left for people to know it and those who knows it then was also making a good use of it just like the way we are currently doing right now, secondly don't think that it was because of how low the price of Bitcoin is then that made people to disregard it, excluding the existence of DCA then is like saying that there was no investment when Bitcoin started, perhaps you are thinking that as you are learning about it now means that is not long it was introduced, however how would you no that Lump sum came on existence before DCA?.
Dollar Cost Averaging (DCA) is an investment strategy that plays an important role in Bitcoin. (DCA) plays an important role in investing in Bitcoin, because it can be said that (BTC) is considered the best method for a long-term chapter (DCA). The goal of dollar cost averaging is to apply value investing principles to regular investments.
The term DCA is said to have been first coined by Benjamin Graham in his 1949 book The Intelligent Investor. Graham writes that dollar cost averaging is something that practitioners will typically invest the same number of dollars in a stock each week or month or quarter.
From this we can say (DCA) is not something that came from nowhere. A review of history shows its rise long before the advent of Bitcoin.
