what is the area of economics that dont work without bitcoin ?
I am thinking you mean which country uses bitcoin more, and if this was your question, then you need to know people of many countries uses Bitcoin, more answer to that awaits your on the search or someone would reply here to it.
What I can tell you and I think you -newbie- would be good to know if Bitcoin is legal and used in your own country.
And every economical area rhymes with Bitcoin ones its accepted between the parties.
