In what specific countries in Asia bitcoin is illegal? As far as I know only China did prohibited those ICOs but bitcoin isn't ban there. I don't know on what country is OP is preferring to. Asia is a continent and not a country and it's compose of many countries and has a lot of parts, Middle East Asia, South East Asia, etc.
I think you are generalizing all Asian countries just because China banned ICOs and other exchange and trading sites. You need to study a little about geography because Japan and South Korea are dominating the btc trading in the cryptocurrency market.
That's what I think too, he's generalizing Asia.
