I am surprised that the countries in Asia only included Singapore on where BTC was googled the most. What happened to China and their support?
Check my previous post and you will find more countries, the one OP shared was only the top 10. Regarding the China missing on the least, reason is simple: Google is banned in China.
That list could soon be expended with the Central African Republic as the country has become the world's second nation that has adopted Bitcoin as legal tender. The only problem is that very few people have electricity there, let alone mobile phones and internet. Judging by
some stats I found, around 11% of the population has access to the Internet. That's a bit more than 550.000 citizens. 14% of the total population have electricity in their homes.
As a matter of fact, Central African Republic is the 2nd on the list with the 95 score meaning bitcoin term was almost as popular as in El Salvador. The reason why it's missing on the list in the first post is because Google excludes countries with low search volume and as you pointed out that only 11% of the population has access to the Internet no wonder that their search volume is low.
