^ I bought Bitcoin because i believed in it.
Now, guess why i'm still buying...
I guess that you are still buying because 1) your investment thesis has not fundamentally changed and/or 2) you have not yet reached a point of having enough (or having more than enough), which truly is not an easy place to objectively assess regarding how much is enough (or more than enough).

The correct answer was, however, "Because i'm still believing in Bitcoin".
or its a "i believe in math, therefore i buy bitcoin" kinda thing
