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?.
DCA has been in existence before bitcoin was created, and it is used by people to achieve something that they cannot afford to buy once because it is very expensive. However, I haven't practiced it personally on investment but I have used such method to acquire a land. I was saving a certain amount whenever I get paid at work for two years and when the funds got the the amount that I needed, I looked for a land and purchased it.
My sister also set up her business and expand it with DCA. She was able to have 40% of the money that she needed to set up her business, and she told me she will start the business then I told her how will she go about the other part of the money, and she explained to me that she would buy the important items needed for starting the business, and when she gets paid, every month she will be buying more items to the shop in order to continue increasing the items till she will buy everything she needs completely. It worked for her and now she has a big shop.
DCA on bitcoin is good because, it doesn't keep you waiting but gives you the opportunity to buy right away continuosly either weekly or monthly for you to continue growing and building your bitcoin investment portfolio overtime. Many people are used to saving some percentage of their income in banks for more than 4 years without touching a dime, such people can DCA on bitcoin consistently and persistently for long periods of time. Why I love DCA is that it has the power of making steady little gathering into something very big beyond your expectations.
