ELI5: Why do plastic bottles have pointed bottoms? Also, how come others like Gatorade completely ignore this and don't have it?

The pointed bottom helps provide structure to the bottle. If it didn't have this, the bottle would crumple a lot. Gatorade bottles are made of a harder plastic than most plastic bottles, so they don't need the shape to keep their form.
