Awesome!
On the price feed:
You can define a whitelist of accounts providing a feed, then e.g. write a script that merely copies bitCNY/bitbtc feed.. As long as Gdex BTC is not trustless or sufficiently decentralized having gcny as a committee owned bitasset makes no sense and would carry wring notion of trust (i.e. committee should not be made owner, please not that committee can't give it back and would to disable it). Bottom line is some more thought and preparation is necessary beforehand imo, and starting it centralized is most reasonable
you are not member of committee, how can you say that committee would to disable it?
right, GDEX.BTC is UIA, is centralized asset, gdex team guarantee that GDEX.BTC=BTC.
just in order to try to make GCNY more decentralized, I'd like to consider to introduce committee here, committee can play the role of administrator of GCNY. with no other responsibilities.
