So the results for each of the tables is showing what would have had happened if you would have invested according to the data inputted, and it does not show you what is going to happen into the future.
I personally prefer the idea of newbies to invest into BTC weekly rather than monthly, but yeah it is understandable that sometimes it might be difficult for newbies or anyone else to carry out weekly BTC buying based on cashflow uncertainties. .. issues with not knowing exact income versus expenses.
The idea is indeed better to make purchases weekly so that BTC will increase much faster, but the problem is when the cash flow is unstable and they do not have weekly capital to make purchases.
Why this reason can be justified because buying using the DCA pattern against BTC will be much more profitable because this asset will continue to get an increase moment for each period even though it cannot be separated from the correction process.
DCA is not appropriate if the asset purchased does not provide certainty like BTC so that the basic capital will be suppressed with a much lower selling price.
This is the reason why DCA is more suitable for BTC investment in my opinion.
