So has DACx created UIAs for US stocks so that Chinese can buy them?
The platform and the initiator of the specific project control the subject matter . The UIA is for sharing the economical gain(lost) of the subject matter .
Through UIA in BitShares , the economical right can be made liquid , unlike the traditional crowd-funding platforms .
Stock is just an example . Other projects like the equity of a start-up company can be traded on the blockchain under this model .
And BTA (BitCNY) will benefit from the trading once the business grows . ( of course ,assuming the wallet will be improved so that normal people can trade easily ) .
It's a trust-based model . In the end , you have to trust DACx and the initiator will back the UIA . Just like you have to trust BTC38,coinbase,BTC-e to back your "balance" .
