Does the uptrend or downtrend with the number $BNB matter?

In my opinion, it does, but for myself, how the market is doing is not as important as whether my account is increasing or decreasing, and how the profits/losses are? After nearly 2 months of watching each chart closely during the uptrend, now I open my eyes to see a sea of red...

Should I continue to buy or just lie still and hold on...
