Is there really a way to tell where the majority of bitcoin holders reside? I don't think so. Bitcoin doesn't know nor care about nationality, country, religion, continent... It is a universal borderless currency. Maybe there are indirect ways to correlate users with countries, but that would be very hard to do accurately.
What do you mean by bitcoin was born in Asia? Because of the name Satoshi Nakamoto or do you have some other argument?
I don't think so that Bitcoin most recognized in Asia. It is a universal trend that has been recognized worldwide. In some countries most in America Bitcoin is not only a lucrative investment, even it has a legit to use for means transaction. In fact, Bitcoin is banned in most states in Asia.
