I think that's from big countries with open-minded citizens who have the ability to understand/ use the Internet and actually have the right knowledge about Bitcoin. In the smaller countries, where Bitcoin has been going with the scams, people wouldn't believe it. Try some country in the ASIA, there were lots of scam with Bitcoin involved. There was so much that every time they think or hear about Bitcoin, they immediately say no and run away. They are not educated about Bitcoin enough to actually believe it.
