Here is Bitcoin DCA calculator
https://dcabtc.com/ that tells how much you will earn if you accumulate Bitcoin in DCA manner for specific period of time. For instance, if we invest 10$ in bitcoin on weekly basis for last one year then after one year we will get
6.52% profit. While investing 10 dollars in bitcoin on weekly basis for last 2 years will give you
-11.15 loss.
Based on this calculations one can figure out how effective DCA can be. May be we can add some other strategy with DCA to lessen the risk involved. DCA will be more effective if you buy during DIP and there is BULL run after you accumulate majority of your Bitcoins.
Actually in this case I don't really like using the DCA Calculator or any instrument to measure the possibility that happens if we invest because in my opinion this will only be an excuse in our limitations and expectations which sometimes backfire on ourselves.
It should be understood that other instruments such as DCA calculators are only a condition where we only roughly calculate what happens if we do DCA from the past but of course we also have to be realistic that calculating things that we certainly cannot grasp will only make your hopes come to naught.
Even though it is not wrong to do that but in the end I think when we want to do DCA with a reflection of the DCA calculator that reflects on the past, it could be a condition where you are only fixated on the past but do not want to welcome the future because there will definitely be a lot of differences that occur from what will be projected by the DCA calculator with the reality faced.
