I am not actually comfortable that Bitcoin mining remains to be dominated by China though I understand that it can because it is a lot cheaper to do it in China compared to other countries. In the past many months, there were many good mining projects locating outside of China and I am hoping this trend can continue so that one day mining will be fairly distributed to as many countries as possible. I hate to think that even Bitcoin is 'Made in China' as the country has a government I don't admire.
