Interesting - for sure.
Also sure (at least to me) is that price feeds need to grow and be taken more seriously as markets mature. Witnesses need to take their responsibility serious and keep up with market price.
We had quite some discussion also with @alt/@bazozi about what a "fair" price for CNY/USD/BTS actually is and I do not think it is possible to come to a *single* price that reflects the BTS price
properly taking into account all the markets and market sentiments in different countries. That is why markets require arbitrators - yet some markets have an offset even on centralized exchanges.
We need to start discussing whether bitCNY is supposed to be worth 1CNY given that it is a digital representative that can be spend easily around the globe, that comes with a 'benefit' over regular fiat CNY (same for USD etc...)
Additionaly, I refrain from acting *quickly* out of markets behaving unexpected. The movements in the last days, shouldn't be take as arguments to modify the smart coin parameters (feeds).
There is a much bigger picture to bitCNY and that is long-term predictability.
Those that sold their BTS on CEX to buy from margin calls on another exchange (DEX) is *business as usual*. Could have well been caused by arbitrators instead of feed producers.
That said, I am not totally against experimentation - but I would rather see small steps and proper discussion before implementation.
Do we understand all the implications of "raising" the price "artificially"?
yesterday is not the first time that we experience such kind of tragedy, and I don't think "sell BTS in CEX and then buy from the margin called positions" can be regarded as "usual business". the point is, the margin call is created by the selling activity in CEX, this is exploitation with clear purpose, not usual arbitration.
from the perspective of Bitshares ecosystem, it is needed to update the rule to remove the chance for such kind of exploitation by shorting, otherwise, Bitshares will never grow up or be able to provide amazing smartcoin services.
does the current BTS price, 0.87 CNY reflect the real value of BTS? I don't think so, it is just the result of one exploitation, if the rules can be optimized to fix the flaw, BTS can stand in another level.
