Actually, if you routinely buy $100 per week for 5 years, the total value invested is $24k. I don't know why the site adds up to $26k in total invested value for 5 years.

Previously, Mr. JJG has provided a table about the DCA strategy in 5 years, but yes, every year where the investor increases the value of his investment to levels, for example, $100 is purchased routinely every week until it reaches 1 year. And in the following year the investor increases the execution per week and so on.

Sometimes it takes accurate planning to reach a more aggressive level than the previous year. I think it's very easy to do if we get increased income in the following year.

Every year the price of btc will be different, it could be that early next year it will be $100k but our investment does not increase, of course that is a factor that must be considered early, if you are able to allocate more, of course that is better.

The 5-year period is the ideal target to apply in investing in bitcoin.  We can consider many new programs in the next investment, for example, large profits will make us set a more aggressive strategy in the next 5 years with an increase in purchases that can reach $150 per week. That is the ladder to reach a wise level in dividing 10 years into two choices with more varied purchase levels.
