Until now, I don't understand why the Chinese are more interested in bitcoin then other people. We need to see more of these mining farms around the world or It will be just a matter of time until we see centralization If we could call it that way. (This is valid for exchanges as well)
There are farms around the world. People just like to fixate on Chinese exchanges for some reason. I guess because they are the biggest. There are also lots in North America and Europe but they get a lot less exposure.
