I'd consider this breaking news, https://www.aex.com/ has added 3 tabs for BitShares based smartcoin markets.
You will be able to trade every altcoin versus bitUSD, bitJPY and bitKRW.
This should give our market pegged assets a huge boost in terms of adoption and liquidity!
SmartCoin markets are not open yet, however, BitShares can be traded for BTC already.
