Bitcoin in Asia is quite popular compared to the western Continents. This is all because of the increased acceptance and the people easily using it an way for getting an additional earning based on its legitimacy. In my thinking bitcoin will be growing high than expected as there is tremendous increase in adoption around the Asian countries.
It's popular in western countries too, usa, canada, brasil, uk, france, germany, spain, russia. In these countries there is also lots of mining activities but these are not like industrial scale mining of assian countries. Assia is more like a capital of cryptocurrency.
