below pics shows the BTC price in China offsite market and poloniex at the same time.
in China the price is about 8593 CNY/BTC, in polo the price is about 1190
8593/1190 = 7.22
the goverment announced USD/CNY rate is about 6.92, however the real market rate today is about 7.15, even so there space for arbitrage trading.
I hope we can build a channel to the fiat USD world with the help of bitUSD and USDT, suppose that let non-USD world always provide more than 2000 bitUSD offer to buy USDT at 0.98-1 bitUSD, and USD world always offer more than 2000 USDT to sell at 1-1.02 bitUSD.
I can play the role to offer bitUSD, anyone would like to play the role to offer USDT?
