Yes, there are a lot of people in China but the average income is only a few hundred dollars a month.
Lets hope that the chinese do start to use bitcoin because then the value will skyrocket.
I think BTC is become more popular after the major media had report to it on Wednesday , more and more people will looking into it, Chinese people like new things and will take more risk ,because they natural are gamble. If you see the BTC price had increase those day after big crash on 1 of May. it might explaining that the report of BTC had made some effort.
