I'm sure bitcoin can help everyone, especially in developing countries. With bitcoin, the citizens can earn income, even bitcoin can provide jobs for unemployment in the country. This is not necessarily the state can provide jobs for all unemployed. Thus per capita income in the country increases, so the state economy increases. The biggest problem of inflation is due to too much money in the country, not because of bitcoin. If only the state was not concerned only with the negative effects of bitcoin, the nations should also think about the positive effects of bitcoin.
