Please correct me if I am wrong
Even in today's modern world, except for a few people in Europe-America, the general public of the entire world does not have a proper understanding of Bitcoin.
For starters bitcoins history is all on the internet and accessible to anybody in the world and isn't region locked as you have put it!
Understanding of bitcoin, well lets just a its a gradual process and most of us just scratch the top and don't get too technical with it.

Except European-American, anyone who have a little idea about Bitcoin also have misconceptions. Due to this problem, many people are unable to invest in a great platform like Bitcoin even if they want to.
Why is bitcoin use fixated around Europe-America

This problem may not seem like a big deal to many, but think about third world countries. A sad reality is, in my country 80-90% of the population are not familiar with Bitcoin.
Is there any way to solve this problem?
I actually think bitcoin use is more in these third world countries as its the best alternative to their failing currencies, for example talk about Zimbabwe, Venezuela, Nigeria(during elections) and several other countries which have shown more interest than developed countries who want regulatory frameworks to help protect their investments.
Tbh its all individual interest and not country based.
