The trading volume in Chinese exchanges so large is because they provided FREE TRADE. actually, it is not so many trades. And in my view, 99% Chinese "investors" is speculating in short-term trades. And in China, it is no use of bitcoin except speculating. Of course, it is caused by gov banned business to accept btc.
I'm just trying to understand the Chinese situation, for instance, are mainland Chinese citizens allowed to visit Hong Kong and participate in that economy as a tourist? Do the same restrictions apply in the Shanghai trade zone?
When you trade on a Chinese exchange for speculation, are you actually allowed to withdrawal in BTC? Are there underground street-level bitcoin/Yaun traders?
Also, what is feel for if/when the Chinese government will ease up on currency restrictions?
