Here's a simple idea to work around the Chinese restrictions on Bitcoin. The idea is basically to use Chinese investors in foreign property as intermediaries to bootstrap a market for Bitcoin exchange in China. This gives Chinese merchants ready access to their local currency, while using Bitcoin to facilitate international trade.
| <- goods <- | | <- yuan <- | | <- property <- |
foreign goods buyer | | Chinese manufacturer | | Chinese property buyer | | foreign property seller |
| -> bitcoin -> | | -> bitcoin -> | | -> bitcoin -> |
(Obviously this model could be used anywhere. I just used Detroit as an example.)
Ideally you would want to do this somewhere that would enforce a contract denominated in Bitcoin.
