It is amount of dark marketplaces and lack of stores that accepts them. I know only 2 local stores in my town that accepts them, and my town is pretty large so 2 is not enough for sure
You are lucky you have 2! It's my dream any store in my town accepts Bitcoin and my town is the capital of the largest country in Europe (Ukraine, yeah it's funny, just learned this yesterday
). Zero stores accepting Bitcoins is not enough for sure.
