In my opinion bitcoin may improve the sittuation of country when there is a serious deflationary or an inflationary problem.
When there is a serious deflationary issue everything can be used as a money to help the lack of money in a circulation. The more easy it is to be used the better. In times of a serious inflation in a country, where money is worth close to the paper it was printed on, the bitcoin becomes invaluable as a big help and convenience.
Bitcoin providing banking infrastructure to some poor countries is another way how bitcoin can improve the economy of country.
Outside of a poor countries with a big financial issues bitcoin can help the sittuation of a people that are in bad economical sittuation by providing an easier way to earn tips.
