Damn, I never expected to not see countries that are very pro bitcoin in this list specially El Salvador. It seems like the people of El Salvador really aren't that curious with bitcoin and may have been just forced to adapt because of the government. With this, we can easily understand that mass adoption cannot be forced. Only when bitcoin and the other altcoins don't get talked crap about by influential people will we see a genuine increase on the number of mass adoption around the world. And only in such conditions should governments try to slowly legalize bitcoin and not as fast as El Salvador which has caused a failure.
I don't believe the people of El Salvador were forced to adopt Bitcoin. They have the option to use their local Fiat as they do with Bitcoin and if you say they they are continually making research to understand Bitcoin more which leads to what is presented in the chat, I'd agree and as for Nigeria, we do know that the Government has not been able to provide the enabling economy for the ever-growing youths to thrive hence the surge into cryptocurrency so no surprise there to see Nigerian on the top of that list.
