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?
If a country accepted bitcoin as one of their legal currency and being used by its people in any kind of transactions, there is big chance that the cryptocurrency might also boost their economy. In japan, bitcoin is already legal and many of their merchants have started to accept bitcoins as one of their mode of payment. Mass adoption of bitcoin into mainstream will eventually contributes to the economic growth.
