Every countries knows dollar and USD is the basis of economic growth of one country specially in third world country. It exist since the money created and comparing to bitcoin it's popularity my answer is no. It because there are many countries didn't know bitcoin.
It is normal if the other countries or most of the countries doesn't know bitcoin because it is common for a new currency since it is just starting to build itself towards the internet and the market so if bitcoin will completely makes something true like if it is already built its reputation and itself then that is the only thing where countries will start to take actions to get into bitcoin.
