Today many countries accept bitcoin as a virtual currency, is it because bitcoin is so high that they think bitcoin can change the country's economy, or because the country has many bitcoin users already?
Yes it is possible that it can improve one economy. But if it legalized by the governments is not impossible to happen the fact that bitcoin was continue spreading worldwide and there are lot of users of it in every country. If bitcoin can change one persons life into better then I believe that it can do so in our economy because bitcoin is type of currency which all of us needed to have a better life.
