Sounds like the Chinese just need to utilize Tor OBFS4 and a decentralized exchange like Bitshares.
There's also currencies like XSPEC (SprectreCoin) with Tor OBFS4 support natively built-in to the wallet. Thus preventing national firewalls from restricting its use.
The fact that BTS/CHY is expanding like crazy means that the Chinese already are using BTS.
I imagine once word starts to spread, that will be a commonly used pair.
