I don't really see the purpose for a BCH exchange. BCH only temporarily scales and solves the problem that BTC deals with. It's like putting a bandaid over a leaking pipe, it doesn't really solve the problem not to mention it pivots investors against each other, this whole Team BCH/Team BTC nonsense. Ultimately the chain getting the most investors and seeing the most strength is BTC, and BCH isn't a better payment platform than numerous other more sophisticated payment platforms. BTC as an asset makes the most sense and BCH just doesn't make a lot of sense to me....I guess we'll see in due time.
