Could not agree more.  Since GAW have taken over at Coinswap I transfer any BTC out following any trades, I am also uncomfortable leaving any quantity of CSD at the exchange.

There has also been several occasions over the past few days when I have not been able to access coinswap.

I also asked Bittrex to add CSD and have seen KryptoKash in IRC ask several times too.  I wonder if the lack of a block explorer is preventing Trex from adding CSD, perhaps block explorer should become a priority?
