Today BigVern @cryptsy announced that the HYC, CNC, CRC, NAN, GIL Markets will be closing on OCT 1st.  This is "Due to inactive developers and low hashrates, this coin will be delisted from the market on Oct 1st, 2013. Wallets will remain open indefinately."

This is the first time to my knowledge that coins are being delisted, since Powercoin (which was 51% attacked).  There have been times when certain coins were removed from trading temporarily due to various problems with those coins.  ChinaCoin (CNC) was the oldest of these coins that will be delisted.

Additionally, WDC and DGC are now in both BTC and LTC markets.  This status was first achieved by GoldCoin in August of 2013.
