Friedcat: I am sorry for my misunderstanding of your bond.
From a long term point of view, I am also worrying some risks in China. As you plan to install more miners, in China, I am wondering how will some governments or departments treat the equipment and electricity.
That's OK. And the concern of me being in China is also very reasonable. I will try to explain it.
1. From the legislation point of view, the Chinese government doesn't ban virtual currencies and commodities, but they only allow a single-sided circulation. For example, a game company can sell their virtual currencies for fiat, but players could not redeem them back as fiat again. This means that things like Bitcoin exchanges are in a illegal, or at best, grey area, in China. Bitcoin itself is fine, so is Bitcoin mining.
2. In the reality, legislation and laws in China are not as respected as in western countries. Orders and policies from the executive administrations matter more. Laws could be easily changed, and in most of the time, the government does not need legislation support to do evil things. But consider that the Chinese government is as slow and bloated as other fellow post-totalitarian ones in history, brand new inventions like Bitcoin is too tiny, too agile, and too beyond-of-its-imagination for it to identify. It has got too many other "bigger" and "more serious" problems to worry about.
3. In China, there are many things that are both illegal in principle and thriving in practice. Pornography, prostitution and gambling are all good examples. In fact, if you strictly follow all the laws and regulations, you could virtually do nothing at all. Almost all companies and enterprises evade taxes, or they can not survive for even a single day. Almost all stores and restaurants bribe to government officers, or they could never pass the regulation requirements, which are impossible to meet in the first place, to get their business licenses. The bottom line is that "don't make the government feel that you are dangerous for them" and "don't shout too loud to make other people believe you are beyond their regulations".
4. It is indeed possible that Bitcoin finally catches its eyes, and it finally decides that Bitcoin is a threat to it. But in my opinion it wouldn't be soon, and the possibility will not be significant larger than EU or US doing it.
5. Mining is not done publicly on the streets, and the electricity use is also limited. In China electricity costs about 0.1$/kWh, which is not much higher than in the US. If we could luckily expand to 1000GH or more, the mining space and electricity consumption might attract the attention of the local government. But that's quite far away, and could be avoided by scatter the Rigs into different places or even cities.
As a Chinese, I hope I didn't fail too much in describing how things work in China, and I hope the explanations above could answer your question.
