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)
The Chinese pretty much have all the supplies so it's a lot cheaper for them to produce or purchase huge amounts of miners since the middelmen is cut out. An European/American business has to either buy the inventory of a retailer or find connections in China to do so. Not to mention the electricity costs and shipping. Adding up tot that bitcoin is still brand new and extremely volatile, an entire business mining bitcoin could potentially go bankrupt if bitcoin were to crash for 6 months.
