I also dont have much places in my country where i can convert the bitcoins to local cash. Even 80 percent people here are unaware of what is bitcoin exactly and how it works. So we dont have much spending options locally but we can spend in online stores and get advantages. With the passage of time Bitcoin will become more popular and then everyone will accept bitcoins.
are you sure 20% percent people in your country aware of bitcoin? i may expect the amount could be even lesser. even though if none of store in your country accept bitcoin you can still buy stuff or goods with bitcoin through international online store,but, the fee will be higher than buying in local
