So lets retweet to Ccex guys!
But even... when people have been checking the volume on Bittrex lately, then this say enough. For me Cryptsy is still one of the biggest exchanges. Bittrex was a pretty hype when they added a lot of new coins that Cryptsy didn't add directly, but now with a few ICO mistakes, people have moved away from Bittrex and move back to Cryptsy or other exchange.
When you check the volume of only 400 - 500 BTC then this say enough, and most of the time the volume is run by a few cons, they have something like 20% of all volume.
C-CEX can use a coin like GROW, and GROW can use a exchange like C-CEX. I believe both will win.
