Arbing Chinese exchanges is very difficult (particularly from BTCE) -- hence why there is a persistent spread between the exchanges. Removing large amounts of CNY into USD and outside of Chinese banks is difficult. One way to take advantage of this spread is to analyze the range of (BTCCNY/USDCNY)-BTCUSD. When at range lows ($4-6 under spread), buy BTCCNY, transfer out and sell for USD. When at range highs ($4-6 above spread), buy BTCUSD, transfer out and sell for CNY.
But when your accounts become heavily outside of equilibrium (i.e. you cannot buy either BTCCNY or BTCUSD), you are stuck until the spread reverts to the mean and you can transfer out without losing profits.
Sorry Jesus, Im trying to understand what are you explaining but it's hard.
1- How can I analyze the range? theorically is BTCCNY/BTCUSD, no?
2- When you talk about range talking in USD means that BTCCNY is at
240 USD and BTCUSD is at
230 USD?, then buy BTCUSD and
transfer where? you mean withdraw the USD to CNY BANK account and viceversa???
Can I do the same with BTCEUR?
Please can you explain that stuff a little bit more detailed? Thanks Jesus!
