Well I don't know how you came up with that figure
I didn't come up with that figure rather it's the
https://dcacryptocalculator.com/ that give results of investing 100$ per week for last five years starting from Oct 30, 2019.
but I gave you the link provided by JJG some weeks ago but perhaps you chose your own website which I don't know how you get to that figure.
I was not aware of
https://dcacryptocalculator.com/ until Dec 2023 when JJG introduce me to that site along with another one.
... but I do use that DCAbtc.com website on a regular basis, and I have found that I have to perform some of the calculations manually in order to get the correct results. There are some other DCA calculating websites out there too.. such as
https://dcacryptocalculator.com/bitcoin and
https://costavg.com/I have done some R&D on these three sites and here are my findings. You can also check and post your findings whether it's correct or not.
Results from
dcacryptocalculator and
costavg converge and give more detail of DCA then
dcabtc. For instance if you want to calculate DCA results of investing 100 dollars into Bitcoin every week for last 3 years or from Dec 25, 2020 to Dec 25, 2023 then
dcacryptocalculator shows that you have ROI of +44.10% and
costavg shows that you have ROI of +42% while
dcabtc says you have a loss of 20%.
