I wonder how you are a "Minergate forum admin and moderator, chat moderator.." not supporting the crypto-currencies your pool supports.

hitbtc.com
cryptopia.co.nz

as far as i know these are exchanges currently supporting BCN, if you want to acquire a unique product you shouldn't be following poloniex. No exchange should have the power to determine if a coin like BCN will be successful or not, certainly volume helps in short-medium term.

Any further questions ask
