Hi, I can answer your question. I was JUST in China.

The Answer: Chinese money is risky

The chinese government has been propping up the yuan for a while. They are dealing with a few issues. Wages are going up, exports are getting harder, and real estate prices have skyrocketed. Their stock market has almost crashed a few times and the only reason it didn't is the government, again, intervened to shore it up.

The wealthy Chinese KNOW that eventually there is going to be a huge drop, so they are trying to move their wealth outside of china. This is hard to do because the government (again) controls how the currency flows. So wealthy Chinese are looking for pretty much any option they can to hedge their bets.

There are a few answers they have found:

1. Invest in foreign companies in industries the government allows.
2. Invest in foreign real estate.
3. Bitcoin

And probably others I'm not aware of. But this is why they want bitcoin: It allows them to move money to the "ether" where it's mostly out of view of the chinese government and nationalized so that IF (when) things crash, they have an exit strategy.

Most wealthy chinese are doing all 3

Not only does this further spread risk, but the combination becomes a perfect escape plan.

1. Shareholder in a foreign company = easy visa
2. Own real-estate = place to go
3. Hold foreign currency (including bitcoin) = can pay for things even if the yuan crashes.

Expect this to continue for a while, especially since China is busy pushing around their neighbors in the south china sea. While the risk of war is low, it's there, and the Chinese know it.
