Was this coin delisted on SouthXchange?
Yes but it was the developers themselves who requested the delisting in order to get rid of autosell pools who were dumping 20k+ crs on the market daily.
Crs has been listed on 2 other exchanges(cfinex and crex24) where it can be traded for btc and also on an exchange where its can be traded vs brazilian real(fxcbit)
