On the flipside, how many Chinese can actually afford these miners?
Are you joking? Don't you watch any financial news? The Chinese economy is off the hook. They 
Their great trade surplus doesn't mean their people are well off. The majority work for pennies on the dollar when manufacturing stuff for the rest of the world.
Check out Shanghai or Beijing sometime. Or just google downtown of anyone of these two, and repeat that again. And note that while they are two cities, there's tens of millions of people in each. Not to mention Hong Kong, Shen Zhen, or other big tier two cities.
Trust me, while the majority might be working for pennies on the dollar (in tier three cities mind you), there is absolutely no shortages of rich people in China.
(Edit: Though I just checked, its closer to 6k for a Nov Jupiter for China KNC due to tax and whatnot. However the hype machine is even crazier there)
