Great new about bittrex!
What's the reasoning behind the people voting to concentrate on increasing volume rather than adding new exchanges?
I am not sure I understand your question...
Voting is for C-Cex so CBX gets listed there;
increasing volume is just to make sure we build a habit of using Bittrex some of the time and give them some business once CBX is listed there.
I believe snatchmonkey meant the poll at the top of this topic.
