One of many other exchanges from China that you might be interested in if this exchange is not to your liking is BTCTrade.im.
As no other fiat currency than CNY is permitted, and no other cryptos than Ripple can be traded here, the exchange is not really available to US investors.Don’t be too sad though, there are many other venues that offer the type of trading this exchange does but with a bigger selection of traded cryptocurrencies and accepted fiat currencies.
