Kucoin is a very good exchange, very good...that being said. Its pricey, and they are selective. XBY wasnt selected and their mk.cap is 88mm, while BBPs is 1.5mm.
Crypto-bridge works well and is earning respect; its only 1BTC to list. We should aim for that.
We don't need a flashy name IMHO. Just a working, honest exchange would do.
