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)
First of all, such facility is a major business / investment, probably made by some business man agreed by the government. Those guys are employees. Don't compare with a guy next door having a couple of miners in the garage.
Second, China does as many investments as possible to get anything possible that holds value. The labor is cheap and somehow they try to get more than their local currency.
This makes gold, dollar, western companies, shares, properties all over the world, cryptocurrencies (and many other things I didn't think of) a target to store their wealth.
