2 Bitcoins.
Chinese Bitcoin vs Gavin Bitcoin
Actually it would be just like everything on the internet
Google vs Baidu
Facebook vs ****
Youtube vs **** (bunch of copy and paste)
Well you know how those went
I guess its safe to say Internet vs China-net
The block solving does not need a lot of bandwidth. Chinese is powerful because their hashing power. Suppose that someone in China controlling a quantum miner, he can solve a block in 5 seconds, no matter where he is located, as long as he managed to get block-solving hash work from a pool that is located on internet backbone, and deliver the solved result back to the pool, that pool will broadcast the finished block to the whole network
Of course if they could control the pool inside main land China, that will give them some convenience, but it is not a must
And I think bitcoin's growth in China provide a good diversification. In western, the bank rules, if banks refuse to open business accounts for bitcoin companies (which is the case today), then bitcoin will not go anywhere(even the merchant accept them will have to convert them to fiat money). However in China it is more complicated, because Chinese banks are controlled by the government officers, and government officers may have different interest. When a government officer decided to go with bitcoin, the banks that he controls will ignore the warning from the central bank (Which had happened in China already, otherwise all those Chinese exchanges would be shutdown already)
