I believe there is going to be increased demand for decentralized exchanges after September 30 when China bans chinese exchanges.
I also believe that bitshare exchange will be a beneficiary of huge portion of this inflo into decentralized exchanges followed by openledger and then etherdalta for Erc20 tokens.
This may impact on the price of bitshare positively. Ethereum is already on the run.
Have you checked the volume of the BITCNY/BTS pair on the Bitshares Asset Exchange? I'd say you're right about China's move giving Bitshares a good bump in activity. :)
