sorry but this news does nothing if its a sign of annoucements to come. This exchange isn't BTS or even BTC exclusive. Its doing the natural thing and supporting all major alt-coins. this was overly hyped.
I think the real news here is that traders can arbitrage bitUSD against CCEDKUSD and keep the peg tighter.
Each additional exchange that adds bitAsset:fiat trading will allow an exponential increase in arbitrage opportunities and our headline product bitUSD will trade closer and closer to its fair market value.
The closer to fair market value we get the more customers we can attract.
Who cares if it benefits other coins too. If BitShares isn't good enough to "win" anyway then what good is it?
