for in my own environment there is no supermarket or mall that receives btc payments directly.
well its not been supported as well from where am I right now, I'm still hoping that bitcoin will be supported by most supermarkets and department stores,
if this happen here then more people will start and adopt this investment, just needed to keep watching and wait for more updates.
I am personally optimistic and I believe that one day we would see more of it. I have seen quite a few around me and I am still seeing few springing up gradually. However, I feel the volatility is one major reasons why most stores or supermarkets do not want to start adopting it yet and luckily, do not know about anyone else, but bitpay has made the whole process easy of auto converting to fiat so that no one would end up being worried about the volatility risk.
Good to know there are few supermarkets around you already accepting Bitcoin. Only time will tell if it will be worthful for supermarkets or not, if so I'm sure more supermarkets around you will adopt it too and spread the word... When a store adopts a good idea the concurrency tends to copy it and do the same thing. The volatility is surely negative for most business, but as you said, they can exchange into fiat anytime... Storing only a part of profit in BTCs is a good strategy especially during the "beta phase" of adoption.
