Sure but the rich Chinese in HK and Singapore dont need BTCC. They already have access to international markets. BTCC gives access to the middle class (dont get me wrong - there is no shortage of whales on there but I do wonder how many of the whales are actually Westerners in disguise).
This is a good point. But my point is that the money between China and these trading zones can be quite porous. But you're right, middle class access will be hammered, which is why I think BTCs in China will eventually trade at a premium relative to ROW.
